The chemical name of Vitamin D 3is:
Cholecalciferol
Understanding the Chemical Name of Vitamin D3
Vitamin D is a fat-soluble vitamin that is essential for calcium absorption and bone health. It exists in a few forms, the most important being Vitamin D2 (ergocalciferol) and Vitamin D3 (cholecalciferol).
The question asks for the chemical name of Vitamin D3. Let's look at the options provided:
Analyzing the Options
We need to identify which of the given chemical names corresponds to Vitamin D3.
- Cholecalciferol: This is one of the main forms of Vitamin D, produced in the skin upon exposure to sunlight or consumed in the diet (from animal sources like fatty fish, egg yolks, and fortified foods).
- Phytonadione: This is the chemical name for Vitamin K1, a vitamin crucial for blood clotting and bone metabolism. It is found in green leafy vegetables.
- Cyanocobalamin: This is a common commercial form of Vitamin B12. Vitamin B12 is essential for nerve function and the formation of DNA and red blood cells.
- Ergocalciferol: This is the chemical name for Vitamin D2. Vitamin D2 is found in some plants (like mushrooms) and fortified foods, and it is also used in supplements.
Based on the analysis, the chemical name for Vitamin D3 is Cholecalciferol.
| Vitamin | Chemical Name |
|---|---|
| Vitamin D3 | Cholecalciferol |
| Vitamin D2 | Ergocalciferol |
| Vitamin K1 | Phytonadione |
| Vitamin B12 | Cyanocobalamin |
Therefore, the correct chemical name for Vitamin D3 is Cholecalciferol.
Revision Table: Key Vitamin Chemical Names
| Vitamin Type | Chemical Name | Primary Role |
|---|---|---|
| Vitamin D3 | Cholecalciferol | Calcium absorption, bone health, immune function |
| Vitamin D2 | Ergocalciferol | Similar to D3, but often considered less potent |
| Vitamin K1 | Phytonadione | Blood clotting, bone metabolism |
| Vitamin B12 | Cyanocobalamin | Nerve function, DNA synthesis, red blood cell formation |
Additional Information on Vitamin D3 and Cholecalciferol
Vitamin D3 (Cholecalciferol) is often called the "sunshine vitamin" because our skin produces it when exposed to ultraviolet B (UVB) rays from sunlight. It is then converted in the liver and kidneys into its active form, calcitriol, which helps regulate calcium and phosphate levels in the body. Adequate levels of Vitamin D3 are important for preventing conditions like rickets in children and osteomalacia or osteoporosis in adults.
While sunlight is a major source, dietary sources of Cholecalciferol include fatty fish (like salmon, mackerel, and sardines), fish liver oils, and smaller amounts in egg yolks. Many foods like milk, orange juice, and cereals are also fortified with Vitamin D.

How many hydrogen bonds involving the backbone CO and NH can be observed in an α‐helix consisting of 15 amino acid residues?
In eukaryotic cells, covalently attached lipids help to anchor some water soluble proteins to the plasma membrane. One group of cytosolic proteins are anchored to the cytosolic face of membrane by a fatty acyl group (e.g. myristate or palmitate). These groups are generally covalently attached to which amino acids present at the N‐terminus of the polypeptide chain?
Which disease is caused by the deficiency of Vitamin 'A'?
