Chemical Information
FooDB NameL-Stachydrine
DescriptionProline betaine, also known as stachydrine or dimethylproline, belongs to the class of organic compounds known as proline and derivatives. Proline and derivatives are compounds containing proline or a derivative thereof resulting from reaction of proline at the amino group or the carboxy group, or from the replacement of any hydrogen of glycine by a heteroatom. Proline betaine is a moderately acidic compound (based on its pKa). Proline betaine exists in all living organisms, ranging from bacteria to humans. Proline betaine is found, on average, in the highest concentration in capers. Proline betaine has also been detected, but not quantified in, several different foods, such as lemons, citrus, pummelo, sweet oranges, and pulses. This could make proline betaine a potential biomarker for the consumption of these foods.
