Product Description of Cholesterol CAS#57-88-5
Cholesterol is a wax-textured lipophilic substance present inside the cells of every living creature. The human liver carries out its endogenous biosynthesis, and this compound may also be ingested from particular food sources. It is indispensable for regular physiological activities and acts as the synthetic precursor of hormones, vitamin D as well as bile acid compounds. While circulating inside blood, cholesterol binds to carrier-proteins and creates lipoprotein complexes for transportation.

Product Applications Of Cholesterol CAS#57-88-5
It is commonly adopted as experimental raw-material for biochemical investigations covering cephalin-related research, cholesterol flocculation test, vitamin-D and hormone-based studies.
This substance can be processed into biochemical testing reagents and blended into emulsifier recipes.
Besides, it acts as essential feedstock for artificial bezoar and hormonal-medicine synthesis. It also works as an emulsifying additive for pharmaceutical goods and different-scale industrial processing.
