Detailed Description





Fungal Cell Membrane Ergosterol Raw Steroid Powder 57-87-4 High Purity 99%



1. Description

Ergosterol (ergosta-5,7,22-trien-3β-ol) is a sterol found in cell membranes of fungi and protozoa, serving many of the same functions that cholesterol serves in animal cells. Because many fungi and protozoa cannot survive without ergosterol, the enzymes that create it have become important targets for drug discovery. Ergosterol is a provitamin form of vitamin D2; exposure to ultraviolet (UV) light causes a chemical reaction that produces vitamin D2.

2. Function

Ergosterol is an important component of the cell membrane of animalcule, plays an important role in keeping the integrality of cell membrane, activity of membrane desmoenzyme, liquidity of membrane, cell livingness and substance transportation. It is an very important medical raw material and can be used to manufacture cortisone and progesterone hormone. It is able to change to VD2 through the change of molecular structure.
