| Description | Leu-Met, also known as L-leu-L-met or leucylmethionine, belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Leu-Met is a very strong basic compound (based on its pKa). (2s)-2-{[(2s)-2-amino-1-hydroxy-4-methylpentylidene]amino}-4-(methylsulfanyl)butanoic acid is found in Trypanosoma brucei. (2s)-2-{[(2s)-2-amino-1-hydroxy-4-methylpentylidene]amino}-4-(methylsulfanyl)butanoic acid was first documented in 2019 (PMID: 31817441). A dipeptide formed from L-leucine and L-methionine residues (PMID: 31398865) (PMID: 31372898) (PMID: 31311944) (PMID: 31266802). |
