Cholesterol-18O

Catalog Number ACM59613513-2
CAS 59613-51-3
Structure Structure
Description Cholesterol-18O is the deuterium labeled Cholesterol. Cholesterol is the major sterol in mammals. It is making up 20-25% of
structural component of the plasma membrane. Plasma membranes are highly permeable to water but relatively
impermeable to ions and protons. Cholesterol plays an important role in determining the fluidity and permeability
characteristics of the membrane as well as the function of both the transporters and signaling proteins. Cholesterol is
also an endogenous estrogen-related receptor α (ERRα) agonist.
