Description

L-Proline is used as asymmetric catalysts in organic synthesis and asymmetric aldol cyclization. It is involved in the Michael addition of dimethyl malonate to alfa-beta-unsaturated aldehydes. It is a precursor of hydroxyproline in collagen. It is an active component of collagen and involved in the proper functioning of joints and tendons. It finds uses in pharmaceutical, biotechnological applications due to its osmoprotectant property. Further, it is used with ninhydrin in the chromatography.
