  • Vitamins Chemical Names and their Deficiency Diseases:
Vitamins Deficiency Diseases
Retinol Xerophthalmia
Tocopherol muscle weakness
Cyanocobalamin Pernicious anemia
Ergocalciferol Rickets

  • Vitamins and their Chemical Names:
  • Retinol - Vitamin A:
    • Vitamin A is the name of a group of fat-soluble retinoids, including retinol, retinal, and retinyl esters.
    • Vitamin A is involved in immune function, vision, reproduction, and cellular communication.
    • Vitamin A is critical for vision as an essential component of rhodopsin, a protein that absorbs light in the retinal receptors, and because it supports the normal differentiation and functioning of the conjunctival membranes and cornea.
    • Vitamin A also supports cell growth and differentiation, playing a critical role in the normal formation and maintenance of the heart, lungs, kidneys, and other organs.
  • Tocopherol - Vitamin E:
    • Vitamin E is a fat-soluble vitamin with several forms, but alpha-tocopherol is the only one used by the human body.
    • Its main role is to act as an antioxidant, scavenging loose electrons—so-called “free radicals”—that can damage cells.
    • It also enhances immune function and prevents clots from forming in heart arteries.
    • Vitamin E has the ability to protect cells from free radical damage as well as stop the production of free radical cells entirely.
    • However, conflicting study results have dimmed some of the promises of using high dose vitamin E to prevent chronic diseases.
  • Cyanocobalamin - Vitamin B12:
    • Vitamin B12 does a lot of things for your body. 
    • It helps make your DNA and your red blood cells.
    • Since your body doesn't make vitamin B12, you have to get it from animal-based foods or from supplements.
    • Our your body doesn't store vitamin B12 for a long time.
  • Ergocalciferol - Viatmin D2:
    • Vitamin D (ergocalciferol-D2, cholecalciferol-D3, alfacalcidol) is a fat-soluble vitamin that helps your body absorb calcium and phosphorus.
    • Having the right amount of vitamin D, calcium, and phosphorus is important for building and keeping strong bones.
    • Vitamin D is used to treat and prevent bone disorders (such as rickets, osteomalacia).
    • Vitamin D is made by the body when the skin is exposed to sunlight.
    • Sunscreen, protective clothing, limited exposure to sunlight, dark skin, and age may prevent getting enough vitamin D from the sun.
    • Vitamin D with calcium is used to treat or prevent bone loss (osteoporosis).
    • Vitamin D is also used with other medications to treat low levels of calcium or phosphate caused by certain disorders.
