General description

Calciol is a hydroxy seco-steroid that is (5Z,7E)-9,10-secocholesta-5,7,10(19)-triene in which the pro-S hydrogen at position 3 has been replaced by a hydroxy group. It is the inactive form of vitamin D3, being hydroxylated in the liver to calcidiol (25-hydroxyvitamin D3), which is then further hydroxylated in the kidney to give calcitriol (1,25-dihydroxyvitamin D3), the active hormone. It has a role as a human metabolite. It is a seco-cholestane, a hydroxy seco-steroid, a member of D3 vitamins, a secondary alcohol and a steroid hormone.

Also known as 5,6-trans-Cholecalciferol, this compound is the major photoisomer of the Vitamin D3 analog and acts as a biologically active form of cholecalciferol (vitamin D). Vitamin D3 induces cell differentiation and prevents the proliferation of cancer cells. Additionally, 5,6-trans-Cholecalciferol activates calcium-dependent signaling pathways crucial for bone metabolism and the immune system. It is a versatile molecule with hypoglycemic and anti-inflammatory properties, making it applicable in immunology, oncology, metabolomics, and biochemical research.

Application

5,6-trans-vitamin D3 has been used:
  • to study the effects of different derivatives of vitamin D3 on bone resorption
  • to study the antiproliferative activity of photoisomers

Features and Benefits

  • Can be used in Metabolomics and Biochemical research
  • High-quality compound suitable for multiple research applications
