Chemical Information
FooDB NameGalactosyl 4-hydroxyproline
DescriptionGalactosyl 4-hydroxyproline belongs to the class of organic compounds known as alpha-amino acyl ester of carbohydrates. Alpha-amino acyl ester of carbohydrates are compounds containing an amino acid esterified with a carbohydrate. Galactosyl 4-hydroxyproline is a very strong basic compound (based on its pKa). Galactosyl 4-hydroxyproline has been detected, but not quantified in, cereals and cereal products. This could make galactosyl 4-hydroxyproline a potential biomarker for the consumption of these foods.
