L-Hydroxyproline is a nonessential amino acid, which means that it is manufactured from other amino acids in the liver; it does not have to be obtained directly through the diet.
L-Hydroxyproline is necessary for the construction of the bodys major structural protein, collagen.
L-Hydroxyproline can improve the flavor and quality of fruit juice drinks, soft drinks, etc.
L-Hydroxyproline gives strength to the protein collagen in the bones, tendons, cartilage and skin.
Is produced by hydroxylation (adding hydroxil or [OH] groups) of proline, with the help of vitamin C. In vitamin C deficiency, proline cannot be converted to hydroxyproline, so collagen does not have enough strength to maintain skin integrity.
