What is Collagen Hydrolyzed?
Collagen is one of the many types of protein found in skin, bone, muscles and internal organs, and it is necessary for the proper functioning of these tissues. Hydrolyzed collagen is usually made from type I collagen (the most abundant collagen of the human body) by an enzymatic hydrolysis process, and is mainly extracted from the bones and the skin from porcine, bovine and fish origin. The amino-acid content of hydrolyzed collagen is the same as collagen: 20 amino acids, including 8 out of 9 essential amino acids (lacking tryptophan). It is characterized by the predominance of glycine, proline and hydroxyproline, which makes up around half of the total amino-acid content. Glycine and proline concentration is 10 to 20 times higher than in other proteins. Hydrolyzed collagen is the end result of the process of breaking down bone and cartilage into small components that are collectively referred to as gelatin. Bone and cartilage are first crushed or ground, defatted, then the calcium con
