FooDB Name | 4-Hydroxyproline |
---|
Description | 4-Hydroxyproline, also known as 4HYP, 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. 4-Hydroxyproline is a very strong basic compound (based on its pKa). 4-Hydroxyproline is found, on average, in the highest concentration within a few different foods, such as sausages, hamburgers, and flaxseeds and in a lower concentration in wheats, green bell peppers, and red bell peppers. 4-Hydroxyproline has also been detected, but not quantified in, several different foods, such as other soy products, parsley, baked beans, cow milks, and lasagna. This could make 4-hydroxyproline a potential biomarker for the consumption of these foods. |
