Sabinsa has been granted its 67th patent, this one on an invention describing selenium containing dipeptides. The US patent (# 8,003,614 B2) deals with the process of manufacturing pharmaceutical and cosmeceutical applications of small peptides incorporating selenium. New products, namely selenodipeptides, based upon the patent will greatly expand the applications of selenium, an essential element for human nutrition and one in which people could be deficient.
L-selenocysteine is the 21st natural amino acid, a selenium containing amino acid, that is a constituent amino acid in several important enzymes including anti-oxidant enzymes such as glutathione peroxidases in the body. The selenium containing nutrients contribute to the biosynthesis of selenoenzymes in the body and selenoamino acids have anti-cancer and other useful properties.
