Description

Kentsin, a contraceptive tetrapeptide, is originally extracted from hamster embryos. Kentsin prevents the maturation of Graafian follicles and consequently inhibits ovulation. Kentsin has opiate properties on gastrointestinal motility[1][3][5].—Metabolism-protein/nucleotide metabolism–C21H40N8O6—-[1]Fox DA, et al.
