Product Information
| Description: | 7-Dehydrocholesterol (7-DHC) is a metabolic intermediate in cholesterol synthesis as well as an unsaturated sterol whose conjugated double bond on the sterol's B ring allows 7-DHC to take up free radicals, thereby counteracting the ability of free radicals to trigger lipid oxidation and iron death. |
| Stability and Solubility Advice: | Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide. We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details. |
