5,6-trans-Vitamin D2（Cat No.:R056471）is a synthetic analog of Vitamin D2 (ergocalciferol), characterized by a trans configuration at the 5,6 position of its sterol ring structure. This modification influences its biological activity, enhancing its stability and affecting its interaction with Vitamin D receptors. 5,6-trans-Vitamin D2 is studied for its potential therapeutic uses in bone health, calcium regulation, and immune function. It may offer advantages over natural Vitamin D2 by improving absorption, prolonging activity in the body, and potentially minimizing side effects associated with conventional Vitamin D supplementation.
