Cyanidin 3-glucoside
Chrysanthemin is an anthocyanin. It is the 3- glucoside of cyanidin. Natural occurrences Chrysanthemin can be found in the roselle plant (''Hibiscus sabdariffa'', Malvaceae), different Japanese angiosperms, '' Rhaponticum'' (Asteraceae), The fruits of the smooth arrowwood (''Viburnum dentatum'', Caprifoliaceae) appear blue. One of the major pigments is cyanidin 3-glucoside, but the total mixture is very complex. In food Chrysanthemin has been detected in blackcurrant pomace, in European elderberry, in red raspberries, in soybean seed coats, in Victoria plum, in peach, lychee and açaí. It is found in red oranges and black rice. It is the major anthocyanin in purple corn (''Zea mays''). Purple corn is approved in Japan and listed in the "Existing Food Additive List" as ''purple corn color''. Biosynthesis The biosynthesis of cyanidin 3-O-glucoside in ''Escherichia coli'' was demonstrated by means of genetic engineering. In '' Arabidopsis thaliana'', a glycosyltran ...

UV Visible Spectrum Cyanidin3G
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact. For h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Victoria Plum
The Victoria plum is a type of English plum. It has a yellow flesh with a red or mottled skin. This plum is a cultivar of the egg plum group (''Prunus domestica'' ssp. ''intermedia''). The fruit is oval or ovate in shape. The ground colour is greenish yellow, mostly covered with purple. The stone is semi-clinging and does not come off completely from the flesh but the skin is easy to pull off. The flesh is quite rough, light yellow and in good development and full maturity is sweet and tasty. Maturation time is mid-to-late September (in some places). It is a good table and household fruit. The tree is quite hardy and grows strongly but is not very large. The bloom is medium-early and self-fertile. It is rarely attacked by diseases, but the fruit is by mold. Flowers must be thinned heavily for the fruits to reach full development. The trees rarely get old due to their high fruit production. The name "Victoria" comes from Queen Victoria (1819–1901). The variety was supposed ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glycosyltransferase
Glycosyltransferases (GTFs, Gtfs) are enzymes (EC 2.4) that establish natural glycosidic linkages. They catalyze the transfer of saccharide moieties from an activated nucleotide sugar (also known as the "glycosyl donor") to a nucleophilic glycosyl acceptor molecule, the nucleophile of which can be oxygen- carbon-, nitrogen-, or sulfur-based. The result of glycosyl transfer can be a carbohydrate, glycoside, oligosaccharide, or a polysaccharide. Some glycosyltransferases catalyse transfer to inorganic phosphate or water. Glycosyl transfer can also occur to protein residues, usually to tyrosine, serine, or threonine to give O-linked glycoproteins, or to asparagine to give N-linked glycoproteins. Mannosyl groups may be transferred to tryptophan to generate C-mannosyl tryptophan, which is relatively abundant in eukaryotes. Transferases may also use lipids as an acceptor, forming glycolipids, and even use lipid-linked sugar phosphate donors, such as dolichol phosphates in eukaryotic ...

Arabidopsis Thaliana
''Arabidopsis thaliana'', the thale cress, mouse-ear cress or arabidopsis, is a small flowering plant native to Eurasia and Africa. ''A. thaliana'' is considered a weed; it is found along the shoulders of roads and in disturbed land. A winter annual with a relatively short lifecycle, ''A. thaliana'' is a popular model organism in plant biology and genetics. For a complex multicellular eukaryote, ''A. thaliana'' has a relatively small genome around 135 megabase pairs. It was the first plant to have its genome sequenced, and is a popular tool for understanding the molecular biology of many plant traits, including flower development and light sensing. Description ''Arabidopsis thaliana'' is an annual (rarely biennial) plant, usually growing to 20–25 cm tall. The leaves form a rosette at the base of the plant, with a few leaves also on the flowering stem. The basal leaves are green to slightly purplish in color, 1.5–5 cm long, and 2–10 mm broad, with ...

Escherichia Coli
''Escherichia coli'' (),Wells, J. C. (2000) Longman Pronunciation Dictionary. Harlow ngland Pearson Education Ltd. also known as ''E. coli'' (), is a Gram-negative, facultative anaerobic, rod-shaped, coliform bacterium of the genus '' Escherichia'' that is commonly found in the lower intestine of warm-blooded organisms. Most ''E. coli'' strains are harmless, but some serotypes ( EPEC, ETEC etc.) can cause serious food poisoning in their hosts, and are occasionally responsible for food contamination incidents that prompt product recalls. Most strains do not cause disease in humans and are part of the normal microbiota of the gut; such strains are harmless or even beneficial to humans (although these strains tend to be less studied than the pathogenic ones). For example, some strains of ''E. coli'' benefit their hosts by producing vitamin K2 or by preventing the colonization of the intestine by pathogenic bacteria. These mutually beneficial relationships between ''E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Purple Corn
Purple corn ( es, maíz morado) or purple maize is group of flint maize varieties ( Zea mays indurata) originating in South America, descended from a common ancestral variety termed "k'culli" in Quechua. It is most commonly grown in the Andes of Peru, Bolivia and Ecuador. Uses Common in Peru, purple corn is used in chicha morada, a drink made by boiling ground purple corn kernels with pineapple, cinnamon, clove, and sugar, and in mazamorra, a type of pudding". In Bolivia, purple corn "Kuli" is used in Api, a smoothie served hot. Color chemistry: anthocyanins The pigment giving purple corn its vivid color derives from an exceptional content of a class of polyphenols called anthocyanins. Cyanidin 3-O-glucoside, also called chrysanthemin, is the major anthocyanin in purple corn kernels, comprising about 73% of all anthocyanins present. Other anthocyanins identified are pelargonidin 3-O-β-D-glucoside, peonidin 3-O-β-D-glucoside, cyanidin 3-O-β-D-(6-malonyl-glucoside), pelargon ...

Red Orange
The blood orange is a variety of orange ( ''Citrus'' × ''sinensis'') (also referred to as raspberry orange) with crimson, almost blood-colored flesh. The distinctive dark flesh color is due to the presence of anthocyanins, a family of polyphenol pigments common to many flowers and fruit, but uncommon in citrus fruits. Chrysanthemin (cyanidin 3-''O''-glucoside) is the main compound found in red oranges. The flesh develops its characteristic maroon color when the fruit develops with low temperatures during the night. Sometimes, dark coloring is seen on the exterior of the rind, as well, depending on the variety of blood orange. The skin can be tougher and harder to peel than that of other oranges. Blood oranges have a unique flavor compared to other oranges, being distinctly raspberry-like in addition to the usual citrus notes. The anthocyanin pigments of blood oranges begin accumulating in the vesicles at the edges of the segments, and at the blossom end of the fruit, and con ...

Lychee
Lychee (US: ; UK: ; ''Litchi chinensis''; ) is a monotypic taxon and the sole member in the genus ''Litchi'' in the soapberry family, ''Sapindaceae''. It is a tropical tree native to Southeast and Southwest China (the Guangdong, Fujian, Yunnan and Hainan provinces), Assam, Vietnam, Laos, Myanmar, Thailand, Malaya, Jawa, Borneo, Philippines and New Guinea. The tree is introduced into Cambodia, Andaman Islands, Bangladesh, East Himalaya, India, Mauritius and Réunion. The cultivation in China is documented from the 11th century. China is the main producer of lychees, followed by Vietnam, India, other countries in Southeast Asia, the Indian Subcontinent, Madagascar and South Africa. A tall evergreen tree, the lychee bears small fleshy fruits. The outside of the fruit is pink-red, roughly textured, and inedible, covering sweet flesh eaten in many different dessert dishes. Lychee seeds contain methylene cyclopropyl glycine which can cause hypoglycemia associated with outbreaks ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Peach
The peach (''Prunus persica'') is a deciduous tree first domesticated and cultivated in Zhejiang province of Eastern China. It bears edible juicy fruits with various characteristics, most called peaches and others (the glossy-skinned, non-fuzzy varieties), nectarines. The specific name ''persica'' refers to its widespread cultivation in Persia (modern-day Iran), from where it was transplanted to Europe. It belongs to the genus ''Prunus'', which includes the cherry, apricot, almond, and plum, in the rose family. The peach is classified with the almond in the subgenus '' Amygdalus'', distinguished from the other subgenera by the corrugated seed shell (endocarp). Due to their close relatedness, the kernel of a peach stone tastes remarkably similar to almond, and peach stones are often used to make a cheap version of marzipan, known as persipan. Peaches and nectarines are the same species, though they are regarded commercially as different fruits. The skin of nectarines ...

Seed
A seed is an embryonic plant enclosed in a protective outer covering, along with a food reserve. The formation of the seed is a part of the process of reproduction in seed plants, the spermatophytes, including the gymnosperm and angiosperm plants. Seeds are the product of the ripened ovule, after the embryo sac is fertilized by sperm from pollen, forming a zygote. The embryo within a seed develops from the zygote, and grows within the mother plant to a certain size before growth is halted. The seed coat arises from the integuments of the ovule. Seeds have been an important development in the reproduction and success of vegetable gymnosperm and angiosperm plants, relative to more primitive plants such as ferns, mosses and liverworts, which do not have seeds and use water-dependent means to propagate themselves. Seed plants now dominate biological niches on land, from forests to grasslands both in hot and cold climates Climate is the long-term weather p ...
