Proline
Proline is an amino acid that, like glycine and hydroxyproline, occurs in high concentrations in cartilage protein. More specifically, collagen in cartilage, tendons, ligaments and bones consists of 12% of the amino acid proline, 30% of the amino acid glycine and 12-14% of the amino acid hydroxyproline. Feeding gelatine or collagen hydrolysate has proven effective in supporting collagen formation.
