Saint-Maur-des-Fossés
Saint-Maur-des-Fossés () is a Communes of France, commune in Val-de-Marne, the southeastern suburbs of Paris, suburbs of Paris, France, from the Kilometre Zero, centre of Paris. History Abbey Saint-Maur-des-Fossés owes its name to Saint-Maur Abbey, founded in 638 by Queen Nanthild, regent for her son Clovis II, at a place called ''Fossati'' in Medieval Latin and ''Les Fossés'' in modern French language, French, meaning "the moats". This place, located at the narrow entrance of a loop where the river Marne (river), Marne made its way round a rocky outcrop,"Saint-Maur au fil du temps" was probably named after the moats of an ancient Celts, Celtic oppidum and later a Roman Empire, Roman Castra, castrum; the site was known in medieval documents as ''Castrum Bagaudarum'', at a time when the mar ...

San Diego
San Diego ( , ) is a city on the Pacific coast of Southern California, adjacent to the Mexico–United States border. With a population of over 1.4 million, it is the List of United States cities by population, eighth-most populous city in the United States. San Diego is the county seat, seat of San Diego County. It is known for its mild Mediterranean climate, extensive List of beaches in San Diego County, beaches and List of parks in San Diego, parks, long association with the United States Navy, and recent emergence as a wireless, electronics, List of hospitals in San Diego, healthcare, and biotechnology development center. Historically home to the Kumeyaay people, San Diego has been referred to as the ''Birthplace of California'', as it was the first site visited and settled by Europeans on what is now the West Coast of the United States. In 1542, Juan RodrÃguez Cabrillo claimed the area for Spain, forming the basis for the settlement of Alta California, 200 years later. ...

Monogalactosyldiacylglycerol Synthase
In enzymology, a monogalactosyldiacylglycerol synthase () is an enzyme that catalyzes the chemical reaction :UDP-galactose + 1,2-diacyl-sn-glycerol \rightleftharpoons UDP + 3-beta-D-galactosyl-1,2-diacyl-sn-glycerol Thus, the two substrates of this enzyme are UDP-galactose and 1,2-diacyl-sn-glycerol, whereas its two products are UDP and 3-beta-D-galactosyl-1,2-diacyl-sn-glycerol. This enzyme belongs to the family of glycosyltransferases, specifically the hexosyltransferases. The systematic name A systematic name is a name given in a systematic way to one unique group, organism, object or chemical substance, out of a specific population or collection. Systematic names are usually part of a nomenclature. A semisystematic name or semitrivi ... of this enzyme class is UDP-galactose:1,2-diacyl-sn-glycerol 3-beta-D-galactosyltransferase.

Plastid
A plastid is a membrane-bound organelle found in the Cell (biology), cells of plants, algae, and some other eukaryotic organisms. Plastids are considered to be intracellular endosymbiotic cyanobacteria. Examples of plastids include chloroplasts (used for photosynthesis); chromoplasts (used for synthesis and storage of pigments); leucoplasts (non-pigmented plastids, some of which can cellular differentiation, differentiate); and apicoplasts (non-photosynthetic plastids of apicomplexa derived from secondary endosymbiosis). A permanent primary endosymbiosis event occurred about 1.5 billion years ago in the Archaeplastida cladeEmbryophyte, land plants, red algae, green algae and glaucophytesprobably with a cyanobiont, a symbiotic cyanobacteria related to the genus ''Gloeomargarita lithophora, Gloeomargarita''. Another primary endosymbiosis event occurred later, between 140 and 90 million years ago, in the photosynthetic plastids ''Paulinella'' amoeboids of the cyanobacteria genera '' ...

Protein
Proteins are large biomolecules and macromolecules that comprise one or more long chains of amino acid residue (biochemistry), residues. Proteins perform a vast array of functions within organisms, including Enzyme catalysis, catalysing metabolic reactions, DNA replication, Cell signaling, responding to stimuli, providing Cytoskeleton, structure to cells and Fibrous protein, organisms, and Intracellular transport, transporting molecules from one location to another. Proteins differ from one another primarily in their sequence of amino acids, which is dictated by the Nucleic acid sequence, nucleotide sequence of their genes, and which usually results in protein folding into a specific Protein structure, 3D structure that determines its activity. A linear chain of amino acid residues is called a polypeptide. A protein contains at least one long polypeptide. Short polypeptides, containing less than 20–30 residues, are rarely considered to be proteins and are commonly called pep ...

Lipid
Lipids are a broad group of organic compounds which include fats, waxes, sterols, fat-soluble vitamins (such as vitamins A, D, E and K), monoglycerides, diglycerides, phospholipids, and others. The functions of lipids include storing energy, signaling, and acting as structural components of cell membranes. Lipids have applications in the cosmetic and food industries, and in nanotechnology. Lipids are broadly defined as hydrophobic or amphiphilic small molecules; the amphiphilic nature of some lipids allows them to form structures such as vesicles, multilamellar/ unilamellar liposomes, or membranes in an aqueous environment. Biological lipids originate entirely or in part from two distinct types of biochemical subunits or "building-blocks": ketoacyl and isoprene groups. Using this approach, lipids may be divided into eight categories: fatty acyls, glycerolipids, glycerophospholipids, sphingolipids, saccharolipids, and polyketides (derived from condensatio ...

Monogalactosyldiacylglycerol
Galactolipids are a type of glycolipid whose sugar group is galactose. They differ from glycosphingolipids in that they do not have nitrogen in their composition. They are the main part of plant membrane lipids where they substitute phospholipids to conserve phosphate for other essential processes. These chloroplast membranes contain a high quantity of monogalactosyldiacylglycerol (MGDG) and digalactosyldiacylglycerol (DGDG). They probably also assume a direct role in photosynthesis, as they have been found in the X-ray structures of photosynthetic complexes. Galactolipids are more bioavailable than free fatty acids, and have been shown to exhibit COX mediated anti-inflammatory activity. Bio-guided fractionation of spinach leaves (''Spinacia oleracea'') revealed alpha-linolenic acid galactolipids (18:3, n-3) were responsible for inhibitory effects on tumor promoter-induced Epstein-Barr virus (EBV) activation. Recently, it has been demonstrated that this same galactolipid, 1,2- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phosphatidylethanolamine
Phosphatidylethanolamine (PE) is a class of phospholipids found in biological membranes. They are synthesized by the addition of cytidine diphosphate-ethanolamine to diglycerides, releasing cytidine monophosphate. S-Adenosyl methionine, ''S''-Adenosyl methionine can subsequently Methylation, methylate the amine of phosphatidylethanolamines to yield phosphatidylcholines. Function In cells Phosphatidylethanolamines are found in all living cells, composing 25% of all phospholipids. In human physiology, they are found particularly in nervous tissue such as the white matter of brain, nerves, neural tissue, and in spinal cord, where they make up 45% of all phospholipids. Phosphatidylethanolamines play a role in membrane fusion and in disassembly of the contractile ring during cytokinesis in cell division. Additionally, it is thought that phosphatidylethanolamine regulates membrane curvature. Phosphatidylethanolamine is an important precursor, substrate (biochemistry), substrate, or d ...
