Cholesteryl linoleate is a cholesterol ester found in LDL. Cholesteryl linoleate is transferred to the plasma membrane of macrophages and CHO cells expressing 15-lipoxygenase (15-LO) via LDL receptor-related protein (LRP) where it undergoes oxidation to form cholesteryl linoleate hydroperoxides.

Speract TFA is a sea urchin egg peptide that regulates sperm motility, also stimulates sperm mitochondrial metabolism.The stimulation of sperm with speract depolarizes the mitochondrion and increases the levels of NADH.?Surprisingly, these responses are independent of external Ca(2+) and are due to the increase in intracellular pH (pHi) induced by speract.?
