Aspartame is a methyl ester of the aspartic acid/phenylalanine dipeptide. Alitame is an aspartic acid-containing dipeptide sweetener. Latter is a dipeptide of phenylalanine and aspartic acid. The most altered compounds were the dipeptide, aspartic acid, and aminobutyric acid. This dipeptide is then condensed with glycine by glutathione synthetase to form glutathione. As a protease it cleaves a glycine-glycine dipeptide at its own C terminus. A dipeptide is an organic compound derived from two amino acids. Synthesis of Z-Fluoro alkene dipeptide isosteres. "N"-Acetylcarnosine (NAC) is a naturally occurring compound chemically related to the dipeptide carnosine. Glycylglycine is the dipeptide of glycine, making it the simplest peptide. The two joined amino acids are called a dipeptide. ACE hydrolyzes peptides by the removal of a dipeptide from the C-terminus. A well known dipeptide is aspartame, an artificial sweetener. E-64 possesses a "trans"-epoxysuccinic acid group coupled to a modified dipeptide. NLRP1 recognizes lethal toxin from "Bacillus anthracis" and muramyl dipeptide.
