Chemical Information
FooDB NameL-Homoarginine
DescriptionL-Homoarginine 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). L-Homoarginine is a very strong basic compound (based on its pKa). L-Homoarginine has been detected, but not quantified in, grass pea and milk (cow). This could make L-homoarginine a potential biomarker for the consumption of these foods.
