Note:-
- Cobalt is found in Vitamin B12.
- Synthesis of vitamins cannot be done by the cells of body. It is fulfilled by the vitamin containing food.
- However, synthesis of vitamin D and K take place in our body.
- Bleeding gum, falling of teath, Fragile bones and delayed wound healing occur due to deficiency of vitamin C.
- Deficiency of calcium mainly occur in absence of vitamin D.
- Synthesis of vitamin D takes place by the ultra violet rays present in the sunlight through cholesterol (ergosterol) of skin. Vitamin D2 is known as ergocalciferol.
- Vitamin K is synthesized in our colon by the bacteria and from there it is absorbed.
- Vitamin A is mainly stored in liver.
- Use of polished rice in human diet cause Beriberi.
