Lunasin
Lunasin is a peptide found in soy and some cereal grains, which has been the subject of research since 1996 focusing on cancer, cholesterol and cardiovascular disease and inflammation.
==Discovery==
Lunasin is a peptide that can be found in soy, barley, wheat, and rye. It is found both in grains originating in the American continents as well as the old world continents. This polypeptide was originally isolated, purified, and sequenced from soybean seed in 1987. Although uncertain about the peptide’s biological activity, the Japanese team of researchers described it as a 43-amino acid peptide, noting specifically the unusual poly (L-aspartic acid) sequence at the carboxyl terminus. Subsequent research at the laboratory of Prof Ben de Lumen at the University of California-Berkeley, identified the peptide as a subunit of the cotyledon-specific 2S albumin.〔"A novel methionine-rich protein from soybean cotyledon: cloning and characterization of cDNA (Accession No. AF005030)" in 〕 The name of the protein was chosen from the Filipino word ''lunas'', which means "cure".〔(【引用サイトリンク】title=Lunasin: a Cancer Preventive Peptide in Seeds )〕 The authors on the paper describing the discovery of lunasin were Alfredo F. Galvez, Na Chen, Janet Macasieb and Ben O. de Lumen
