Amino acid. Structure of a typical L -alpha-amino acid in the "neutral" form. Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. [1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins. [2]
Nervonic acid has 24 carbons, is found in brain glycolipids (Nervon) and sphingomyelin, and is a cis -15-mono-unsaturated fatty acid. C 23 H 45 CO 2 H, IUPAC organization name (Z)-tetracos-15-enoic acid, numerical representation 24:1, n-9, molecular weight 366.62, melting point 42–43 °C. CAS Registry Number 506-37-6.

DNA and RNA codon tables. The standard RNA codon table organized in a wheel. A codon table can be used to translate a genetic code into a sequence of amino acids. [1][2] The standard genetic code is traditionally represented as an RNA codon table, because when proteins are made in a cell by ribosomes, it is messenger RNA (mRNA) that directs ...
Fatty acids are mainly used in the production of soap, both for cosmetic purposes and, in the case of metallic soaps, as lubricants. Fatty acids are also converted, via their methyl esters, to fatty alcohols and fatty amines, which are precursors to surfactants, detergents, and lubricants. [ 17 ]
The systematic IUPAC name is not always the preferred IUPAC name, for example, lactic acid is a common, and also the preferred, name for what systematic rules call 2-hydroxypropanoic acid. This list is ordered by the number of carbon atoms in a carboxylic acid.
Lysine (symbol Lys or K) [2] is an α-amino acid that is a precursor to many proteins.It contains an α-amino group (which is in the protonated −NH + 3 form when dissolved in water), an α-carboxylic acid group (which is in the deprotonated −COO − form when dissolved in water), and a side chain lysyl ((CH 2) 4 NH 2), classifying it as a basic, charged (at physiological pH), aliphatic ...
Histidine (symbol His or H) [2] is an essential amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated –NH 3 + form under biological conditions), a carboxylic acid group (which is in the deprotonated –COO − form under biological conditions), and an imidazole side chain (which is partially protonated), classifying it as a ...
