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.
In animal tissue, BCKDC catalyzes an irreversible step [2] in the catabolism of the branched-chain amino acids L-isoleucine, L-valine, and L-leucine, acting on their deaminated derivatives (L-alpha-keto-beta-methylvalerate, alpha-ketoisovalerate, and alpha-ketoisocaproate, respectively) and converting them [3] to α-Methylbutyryl-CoA, Isobutyryl-CoA and Isovaleryl-CoA respectively.
The 3 substrates of this enzyme are ATP, L-valine, and tRNA(Val), whereas its 3 products are AMP, diphosphate, and L-valyl-tRNA(Val). This enzyme belongs to the family of ligases, to be specific those forming carbon-oxygen bonds in aminoacyl-tRNA and related compounds. The systematic name of this enzyme class is L-valine:tRNAVal ligase (AMP ...

green marked amino end (L-Valine) and blue marked carboxyl end (L-Alanine) A tripeptide is a peptide derived from three amino acids joined by two or sometimes three peptide bonds. [1] As for proteins, the function of peptides is determined by the constituent amino acids and their sequence.
The C-terminus (also known as the carboxyl-terminus, carboxy-terminus, C-terminal tail, carboxy tail, C-terminal end, or COOH-terminus) is the end of an amino acid chain (protein or polypeptide), terminated by a free carboxyl group (-COOH). When the protein is translated from messenger RNA, it is created from N-terminus to C-terminus. The ...

L Leu Leu is essential for humans, and behaves similarly to isoleucine and valine. Methionine: M Met Met is essential for humans. Always the first amino acid to be incorporated into a protein, it is sometimes removed after translation. Like cysteine, it contains sulfur, but with a methyl group instead of hydrogen. This methyl group can be ...
