What is the scientific name of Vitamin A.?

  • A.Retinol
  • B.Thiamine
  • C.Riboflavin
  • D.Niacin

Answer: A

The scientific name of vitamin A is retinol.

Retinol is the fat-soluble alcohol form of vitamin A. Its derivative retinal forms rhodopsin, the visual pigment of the rods, which is why deficiency causes night blindness before it damages the cornea (xerophthalmia).

The other three are water-soluble B vitamins: thiamine is B1 (deficiency causes beriberi), riboflavin is B2, and niacin is B3 (deficiency causes pellagra).
