Valine (symbol Val or V) [4] is an α-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), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid.
Amino acids with the structure NH + 3 −CXY−CXY−CO − 2, such as β-alanine, a component of carnosine and a few other peptides, are β-amino acids. Ones with the structure NH + 3 −CXY−CXY−CXY−CO − 2 are γ-amino acids, and so on, where X and Y are two substituents (one of which is normally H). [7]
Isovaline is an isomer of the common amino acid valine, with the position of one methyl group shifted slightly (from position 3 to position 2). The structure of isovaline is also somewhat similar to the amino acids GABA and glycine , the chief inhibitory neurotransmitters in the mammalian central nervous system .
R)-2,3-Dihydroxy-isovalerate, also known as α,β-dihydroxyisovalerate, is an important intermediate in the biosynthesis of branched-chain amino acids, particularly valine, leucine, and isoleucine. [1]
Chemical formula: C 9 H 11 N O 2 Molar mass: 165.19 g·mol −1 Systematic name: 2-Amino-3-phenyl-propanoic acid Abbreviations: F, Phe Synonyms: alpha-Amino-beta-phenylpropionic acid (2R)-2-amino-3- phenylpropanoic acid (2S)-2-amino-3-phenylpropanoic acid
Isovaleric acid, also known as 3-methylbutanoic acid or β-methylbutyric acid, is a branched-chain alkyl carboxylic acid with the chemical formula (CH 3) 2 CHCH 2 CO 2 H. It is classified as a short-chain fatty acid. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. The compound occurs naturally and can be found in ...
