生物活性
Speract 是一種調(diào)節(jié)精子活力的海膽蛋肽，也刺激精子線(xiàn)粒體代謝。體外研究
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.
