Molecular weight: 384.6377

Level: br

Purity: ≥ 100000 iu/g (microencapsulated powder)

Grade: high purity

Purity: ≥ 38million iu/g (crystal)

Physicochemical Properties: white powder, microcapsule powder is spray powder with oil and emulsifier, starch dextrin, etc., which can only be dispersed in water. Definition: active 7-dehydrocholesterol. It is produced by 7-dehydrocholesterol after ultraviolet irradiation. In fact, it is a kind of prohormone, which is inactive in itself. It needs to be metabolized into 25 hydroxycholecalciferol in the liver first, and then it can be active after further hydroxylation in the kidney

Purpose: biochemical experiment; Scientific research.

Storage: 2 ~ 8 ℃, away from light
