Chemical Information
FooDB NameL-Glutamic acid hydrochloride
DescriptionDL-Glutamate, also known as E or DL-glutamic acid, belongs to the class of organic compounds known as glutamic acid and derivatives. Glutamic acid and derivatives are compounds containing glutamic acid or a derivative thereof resulting from reaction of glutamic acid at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. DL-Glutamate is a very strong basic compound (based on its pKa). DL-Glutamate exists in all living organisms, ranging from bacteria to humans. DL-Glutamate is found, on average, in the highest concentration in a few different foods, such as red bell peppers, wheats, and oats and in a lower concentration in red beetroots, green beans, and ryes. DL-Glutamate has also been detected, but not quantified in, broccoli. This could make DL-glutamate a potential biomarker for the consumption of these foods.
