Patent ID: 7671041

Claim:
A hydrolysate of avian cartilage comprising a peptidic fraction and glycosaminoglycans, wherein: a) it comprises: 45% to 70% by weight of hydrolysed type II collagen, 9% to 15% by weight of chondroitin sulphate, 0.5% to 2% by weight of hyaluronic acid; b) said peptidic fraction comprises: 2.7% to 3.3% by weight of valine, 2.0% to 2.4% by weight of isoleucine, 2.2% to 2.6% by weight of phenylalanine, 3.8% to 4.2%, by weight of lysine 0.4% to 0.6% by weight of tryptophane, 5.5% to 8.7% by weight of hydroxyproline, 0.7% to 1 .8% by weight of hydroxylysine, and the molar ratio of hydroxyproline to hydroxylysine is between 5.0 and 8.0; c) the average molecular weight of said peptidic fraction is between 500 and 1000 Daltons.
