描述
2,3-didehydroalanine, also known as alpha,beta-dehydroalanine or 2-aminoacrylate, is a member of the class of compounds known as alpha amino acids. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). 2,3-didehydroalanine is soluble (in water) and a moderately acidic compound (based on its pKa). 2,3-didehydroalanine can be found in a number of food items such as dandelion, cherimoya, strawberry, and mango, which makes 2,3-didehydroalanine a potential biomarker for the consumption of these food products. 2,3-didehydroalanine exists in all living species, ranging from bacteria to humans. In humans, 2,3-didehydroalanine is involved in the thyroid hormone synthesis. Dehydroalanine (Cα,β-didehydroalanine, (alpha)-(beta)-di-dehydroalanine, or 2,3-didehydroalanine) is a dehydroamino acid. It is a hypothetic molecule that does not exist except as a residue found as a residue in peptides of microbial origin. It is unusual in having an unsaturated backbone .
