Classification of vitamins


These vitamins are water soluble and absorbed by the intestine and carried by the circulatory system into tissues that are used. As the body has no capacity to store the excess of such vitamins that is why it is secreted out from the body in the form of little water drops. Thus, soluble vitamins require daily replacement.

Those vitamins which can be dissolved in water are vitamins B12, B6, folate, niacin, and riboflavin is also known as Vitamin B- Complex and vitamin C. These vitamins are supposed to be watery earlier than the human body could take them up. Vitamins B or C is not utilized by a person's body and does not utilize when it goes

through body scheme on omission.


Fat soluble vitamins are comprised of Vitamin E, K, D, and A that dissolve in fats and are accumulated in human body. Such vitamins require the aid of fats to be absorbed. The body can store a larger amount of vitamins than water soluble (FAO/WHO, 1988).

Spinach contains Vitamin A, K, folate, manganese, iron and magnesium. In addition, it is crammed with vitamins B 6, 1, and 2, vitamin E and calcium (Lonn, et al, 2006).

The chemical structure of vitamins varies in the nature of the characteristics and also differs greatly and cannot be classified by a general method. Vitamins are immediately recognized when it is discovered that some vitamins can be dissolved in water, while others are not water soluble. Scientists have divided vitamins solubility into fat-soluble vitamins, and water-soluble vitamins.

Fat-soluble vitamins mainly include vitamin A, vitamin D, vitamin E and vitamin K.

Water-soluble vitamins are B vitamins and vitamin C. B vitamins including eight kinds of water-soluble vitamins include vitamin B1, vitamin B2, vitamin B3 (pantothenic acid, throughout acid), vitamin B6 (FAO/WHO, 2002). The human body required food sources. The current classification of vitamins is not perfect. It is based on the physical and chemical properties (e.g., solubility) or chemical nature (Lonn, et al, 2006).

Functions, sources and risks

B6 (pyridoxine) helps in protection from skin diseases and inflammation of the lips.

Vitamin B9 (folic acid) stimulates and regulates blood circulation and is involved in metabolism. Vitamin B10 affects hair growth and preservation of their color.

Vitamin B12 is involved in the blood supply.

Vitamin B15 (calcium) used in circulatory disorders (Lonn, et al, 2006).

Vitamin C (ascorbic acid) is involved in collagen synthesis, carbohydrate metabolism, and tissue regeneration.

Vitamin D promotes the absorption of calcium.

Vitamin E is an antioxidant, prevents vascular ...
