those three amino acids
1amino 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.… …
2Amino acid — This article is about the class of chemicals. For the structures and properties of the standard proteinogenic amino acids, see Proteinogenic amino acid. The generic structure of an alpha amino acid in its unionized form …
3Amino 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… …
4Proteinogenic 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 …
5DNA, RNA and proteins: The three essential macromolecules of life — All living organisms are dependent on three types of very large molecules for essentially all of their biological functions. These molecules are DNA, RNA and proteins, and are classified as biological macromolecules.[1] Without DNA, RNA and… …
6Essential 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… …
7excitatory amino acid — The naturally occurring amino acids L glutamate and L aspartate and their synthetic analogues, notably kainate, quisqualate, and NMDA. They have the properties of excitatory neurotransmitters in the CNS, may be involved in long term potentiation …
8evolution — evolutional, adj. evolutionally, adv. /ev euh looh sheuhn/ or, esp. Brit., /ee veuh /, n. 1. any process of formation or growth; development: the evolution of a language; the evolution of the airplane. 2. a product of such development; something… …
