Calciferol
Calciferol
Calciferol (pronounced: kal-sif-er-ol), also known as Vitamin D, is a group of fat-soluble secosteroids responsible for increasing intestinal absorption of calcium, magnesium, and phosphate, and multiple other biological effects.
Etymology
The term "Calciferol" is derived from the Latin word 'calcis' meaning lime and the Greek word 'ferol' which means to bear or carry. It was named so due to its role in the absorption and carrying of calcium in the body.
Function
In humans, the most important compounds in this group are Vitamin D3 (also known as cholecalciferol) and Vitamin D2 (ergocalciferol). Calciferol is produced in the skin of vertebrates after exposure to ultraviolet B light from the sun or artificial sources.
Deficiency
A deficiency of Calciferol, or Vitamin D, can lead to Rickets in children or Osteomalacia in adults, diseases that weaken the bones.
