Aleksandr Aleksandrovich Shmuk
Aleksandr Aleksandrovich Shmuk (russian: Александр Александрович Шмук) ( in Moscow – 22 January 1945, Moscow) was a Soviet biochemist and recipient of the Stalin Prize in 1942. In 1913 Shmuk finished his studies at the Moscow Agricultural Academy. Between 1923 and 1937 he worked at the All-Union Institute of Tobacco and Low-Grade Tobacco while simultaneously holding a professorship at the Kuban Institute of Agriculture. He studied the biochemistry of tobacco and won (in 1942) the Stalin Prize for his work deriving nicotine, citric acid, and malic acid from low-grade tobacco (makhorka ''Nicotiana rustica'', commonly known as Aztec tobacco or strong tobacco, is a rainforest plant in the family Solanaceae. It is a very potent variety of tobacco, containing up to nine times more nicotine than common species of ''Nicotiana'' suc ...). He is known primarily for his three volume work ''The Chemistry and Technology of Tobacco'' and for his development of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Moscow
Moscow ( , US chiefly ; rus, links=no, Москва, r=Moskva, p=mɐskˈva, a=Москва.ogg) is the capital and largest city of Russia. The city stands on the Moskva River in Central Russia, with a population estimated at 13.0 million residents within the city limits, over 17 million residents in the urban area, and over 21.5 million residents in the metropolitan area. The city covers an area of , while the urban area covers , and the metropolitan area covers over . Moscow is among the world's largest cities; being the most populous city entirely in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent. First documented in 1147, Moscow grew to become a prosperous and powerful city that served as the capital of the Grand Duchy that bears its name.

State Stalin Prize
The USSR State Prize (russian: links=no, Государственная премия СССР, Gosudarstvennaya premiya SSSR) was the Soviet Union's state honor. It was established on 9 September 1966. After the dissolution of the Soviet Union, the prize was followed up by the State Prize of the Russian Federation. The State Stalin Prize (:ru:Сталинская премия, Государственная Сталинская премия, ''Gosudarstvennaya Stalinskaya premiya''), usually called the Stalin Prize, existed from 1941 to 1954, although some sources give a termination date of 1952. It essentially played the same role; therefore upon the establishment of the USSR State Prize, the diplomas and badges of the recipients of Stalin Prize were changed to that of USSR State Prize. In 1944 and 1945, the last two years of the Second World War, the award ceremonies for the Stalin Prize were not held. Instead, in 1946 the ceremony was held twice: in January for the works creat ...

Kuban
Kuban (Russian and Ukrainian: Кубань; ady, Пшызэ) is a historical and geographical region of Southern Russia surrounding the Kuban River, on the Black Sea between the Don Steppe, the Volga Delta and the Caucasus, and separated from the Crimean Peninsula to the west by the Kerch Strait. Krasnodar Krai is often referred to as ''Kuban'', both officially and unofficially, although the term is not exclusive to the krai and accommodates the republics of Adygea, Karachay-Cherkessia, and parts of Stavropol Krai. Cossack settlement The Cossack settlement of Kuban and of the adjacent Black Sea region occurred gradually for over a century, and was heavily influenced by the outcomes of the conflicts between Russia and Ottoman Empire.Azarenkova et al., pp. 8ff. In the mid-18th century, the area was predominantly settled by the mountainous Adyghe tribes. After the Russo-Turkish War of 1768–1774, the population of the area started to show more pro-Russian tendencies. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Biochemistry
Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism. Over the last decades of the 20th century, biochemistry has become successful at explaining living processes through these three disciplines. Almost all areas of the life sciences are being uncovered and developed through biochemical methodology and research.Voet (2005), p. 3. Biochemistry focuses on understanding the chemical basis which allows biological molecules to give rise to the processes that occur within living cells and between cells, Karp (2009), p. 2. in turn relating greatly to the understanding of tissues and organs, as well as organism structure and function. Miller (2012). p. 62. Biochemistry is closely related to molecular biology, which is the study of the molecular mechanisms of biological phenom ...

Tobacco
Tobacco is the common name of several plants in the genus '' Nicotiana'' of the family Solanaceae, and the general term for any product prepared from the cured leaves of these plants. More than 70 species of tobacco are known, but the chief commercial crop is ''N. tabacum''. The more potent variant ''N. rustica'' is also used in some countries. Dried tobacco leaves are mainly used for smoking in cigarettes and cigars, as well as pipes and shishas. They can also be consumed as snuff, chewing tobacco, dipping tobacco, and snus. Tobacco contains the highly addictive stimulant alkaloid nicotine as well as harmala alkaloids. Tobacco use is a cause or risk factor for many deadly diseases, especially those affecting the heart, liver, and lungs, as well as many cancers. In 2008, the World Health Organization named tobacco use as the world's single greatest preventable cause of death. Etymology The English word ''tobacco'' originates from the Spanish word "tabac ...

Nicotine
Nicotine is a naturally produced alkaloid in the nightshade family of plants (most predominantly in tobacco and '' Duboisia hopwoodii'') and is widely used recreationally as a stimulant and anxiolytic. As a pharmaceutical drug, it is used for smoking cessation to relieve withdrawal symptoms. Nicotine acts as a receptor agonist at most nicotinic acetylcholine receptors (nAChRs), except at two nicotinic receptor subunits ( nAChRα9 and nAChRα10) where it acts as a receptor antagonist. Nicotine constitutes approximately 0.6–3.0% of the dry weight of tobacco. Nicotine is also present at ppb-concentrations in edible plants in the family Solanaceae, including potatoes, tomatoes, and eggplants, though sources disagree on whether this has any biological significance to human consumers. It functions as an antiherbivore toxin; consequently, nicotine was widely used as an insecticide in the past, and neonicotinoids (structurally similar to nicotine), such as imidaclopri ...

Citric Acid
Citric acid is an organic compound with the chemical formula HOC(CO2H)(CH2CO2H)2. It is a colorless weak organic acid. It occurs naturally in citrus fruits. In biochemistry, it is an intermediate in the citric acid cycle, which occurs in the metabolism of all aerobic organisms. More than two million tons of citric acid are manufactured every year. It is used widely as an acidifier, as a flavoring, and a chelating agent. A citrate is a derivative of citric acid; that is, the salts, esters, and the polyatomic anion found in solution. An example of the former, a salt is trisodium citrate; an ester is triethyl citrate. When part of a salt, the formula of the citrate anion is written as or . Natural occurrence and industrial production Citric acid occurs in a variety of fruits and vegetables, most notably citrus fruits. Lemons and limes have particularly high concentrations of the acid; it can constitute as much as 8% of the dry weight of these fruits (about 47&nb ...

Malic Acid
Malic acid is an organic compound with the molecular formula . It is a dicarboxylic acid that is made by all living organisms, contributes to the sour taste of fruits, and is used as a food additive. Malic acid has two stereoisomeric forms (L- and D-enantiomers), though only the L-isomer exists naturally. The salts and esters of malic acid are known as malates. The malate anion is an intermediate in the citric acid cycle. Etymology The word 'malic' is derived from Latin ' mālum', meaning 'apple'. The related Latin word , meaning 'apple tree', is used as the name of the genus ''Malus'', which includes all apples and crabapples; and the origin of other taxonomic classifications such as Maloideae, Malinae, and Maleae. Biochemistry L-Malic acid is the naturally occurring form, whereas a mixture of L- and D-malic acid is produced synthetically. File:L-Äpfelsäure.svg, L-Malic acid File:D-Äpfelsäure.svg, D-Malic acid Malate plays an important role in biochemistry. In th ...

Makhorka
''Nicotiana rustica'', commonly known as Aztec tobacco or strong tobacco, is a rainforest plant in the family Solanaceae. It is a very potent variety of tobacco, containing up to nine times more nicotine than common species of ''Nicotiana'' such as ''Nicotiana tabacum'' (common tobacco). More specifically, ''N. rustica'' leaves have a nicotine content as high as 9%, whereas ''N. tabacum'' leaves contain about 1 to 3%. The high concentration of nicotine in its leaves makes it useful for producing pesticides, and it has a wide variety of uses specific to cultures around the world. However, ''N. rustica'' is no longer cultivated in its native North America, (except in small quantities by certain Native American tribes) as ''N. tabacum'' has replaced it. Uses South America ''Nicotiana rustica'' is called ''mapacho'' in South America. It is often used for entheogenic purposes by South American shamans, because of its high nicotine content and comparatively high levels of beta-car ...

VASKhNIL
VASKhNIL (), the acronym for the Lenin All-Union Academy of Agricultural Sciences or the V.I. Lenin Academy of Agricultural Sciences (), was the Soviet Union's academy dedicated to agricultural sciences, operating from 1929 to the dissolution of the Soviet Union in 1992. Built upon the model of the Academy of Sciences of USSR, VASKhNIL included not only a body of academicians but also a vast network of research institutions scattered all over the Union, with thousands of researchers and plant and cattle breeders. History The Academy operated from 1929 to the dissolution of the Soviet Union in 1992. In the 1930s–40s, meetings of the academy members ('sessions' of VASKhNIL) provided the floor for debates between Lysenkoists and geneticists. After Trofim Lysenko had taken control over the Academy, it became for about thirty years a stronghold of Lysenkoism. The proverbial among Russian biologists (July 31–August 7, 1948) organised under control of the Communist Party (J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...
