basic amino acid
1amino acid — ► NOUN ▪ any of a class of about twenty organic compounds which form the basic constituents of proteins and contain both acid and amine groups …
2amino acid — Biochem. any of a class of organic compounds that contains at least one amino group, NH2, and one carboxyl group, COOH: the alpha amino acids, RCH(NH2)COOH, are the building blocks from which proteins are constructed. Cf. essential amino acid.… …
3Amino acid — One of the 20 building blocks of protein. The sequence of amino acids in a protein and, hence, the function of that protein are determined by the genetic code in the DNA. Amino acids are molecules that (in technical terms) contain a basic amino… …
4Amino acid synthesis — For the non biological synthesis of amino acids see: Strecker amino acid synthesis Amino acid synthesis is the set of biochemical processes (metabolic pathways) by which the various amino acids are produced from other compounds. The substrates… …
5amino acid — n. Biochem. any of a group of organic compounds containing both the carboxyl (COOH) and amino (NH2) group, occurring naturally in plant and animal tissues and forming the basic constituents of proteins. Etymology: AMINE + ACID * * * amino acid… …
6amino acid — A compound containing both amino ( NH2) and carboxyl ( COOH) groups. In particular, any of 20 basic building blocks of proteins having the formula NH2 CR COOH, where R is different for each specific amino acid. See: annex 3 …
7Proteinogenic amino acid — Proteinogenic amino acids are those amino acids that can be found in proteins and require cellular machinery coded for in the genetic code [1] of any organism for their isolated production. There are 22 standard amino acids, but only 21 are found …
8Essential amino acid — An essential amino acid or indispensable amino acid is an amino acid that cannot be synthesized de novo by the organism (usually referring to humans), and therefore must be supplied in the diet. Contents 1 Essentiality vs. conditional… …
9amino acid — [ə mi:nəʊ, ə mʌɪnəʊ] noun Biochemistry any of a class of about twenty simple organic compounds which form the basic constituents of proteins and contain both a carboxyl (‒COOH) and an amino (‒NH2) group …
10Basic-helix-loop-helix — A basic helix loop helix (bHLH) is a protein structural motif that characterizes a family of transcription factors. Structure The motif is characterized by two α helices connected by a loop. In general, transcription factors including this domain …
