Chemical Information
FooDB NameO-Acetylhomoserine
DescriptionAcetylhomoserine, also known as homoserine acetate, belongs to the class of organic compounds known as alpha amino acids. These are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Acetylhomoserine is a very strong basic compound (based on its pKa). Acetylhomoserine exists in all eukaryotes, ranging from yeast to humans. Acetylhomoserine is found, on average, in the highest concentration within common pea. Acetylhomoserine has also been detected, but not quantified in, milk (cow) and pulses. This could make acetylhomoserine a potential biomarker for the consumption of these foods.
