https://en.wikipedia.org/wiki/Amino_acidAmino acids are organic compounds that contain amino (−NH+3) and carboxylate −CO−2 functional groups, along with a side chain (R group) specific to each amino acid. The elements present in every amino acid are carbon (C), hydrogen (H), oxygen (O), and nitrogen (N); in addition sulfur (S) is

Essential amino acid - Wikipedia
https://en.wikipedia.org/wiki/Essential_amino_acidAn essential amino acid, or indispensable amino acid, is an amino acid that cannot be synthesized from scratch by the organism fast enough to supply its demand, and must therefore come from the diet. Of the 21 amino acids common to all life forms, the nine amino acids humans cannot synthesize are phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine.

Secondary amino acid - Wikipedia
https://en.wikipedia.org/wiki/Secondary_amino_acidSecondary amino acids are amino acids which do not contain the amino group-NH 2 but is rather a secondary amine.Secondary amino acids can be classified to cyclic acids such as proline and acyclic N-substituted amino acids. In nature, proline, hydroxyproline, pipecolic acid and sarcosine are well-known secondary amino acids. ...

Acide aminé — Wikipédia
https://fr.wikipedia.org/wiki/Acide_aminéUn acide aminé est un acide carboxylique qui possède également un groupe fonctionnel amine. De tels composés organiques ont donc à la fois un groupe carboxyle –COOH et un groupe amine, par exemple une amine primaire –NH2 ou une amine secondaire –NH–. Dans le monde vivant, on connaît environ 500 acides aminés, dont environ 149 ...
Protein - Wikipedia
https://en.wikipedia.org/wiki/ProteinProteins are assembled from amino acids using information encoded in genes. Each protein has its own unique amino acid sequence that is specified by the nucleotide sequence of the gene encoding this protein. The genetic code is a set of three-nucleotide sets called codons and each three-nucleotide combination designates an amino acid, for example AUG …
