Description4-Hydroxyproline, also known as Hyp or oxaceprol, 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 exists in all living species, ranging from bacteria to humans. 4-Hydroxyproline is a potentially toxic compound.
