生物活性
Speract 是一种调节精子活力的海胆蛋肽，也刺激精子线粒体代谢。体外研究
Speract is a decapeptide from the outer jelly layer of the Strongylocentrotus purpuratus egg that upon binding to its receptor in the sperm, stimulates sperm motility, respiration and ion fluxes, among other physiological events. Speract increases NADH levels and depolarizes the sea urchin sperm mitochondrion.
