What are Vitamins, why should we have Vitamins? Vitamins are not same for all organisms. Sometimes the compound is a vitamin for human but not for animals. Many animals can produce vitamins that are necessary for them but humans cannot do that. Vitamins are very much required for every organism. It is an organic compound. An organic compound is a vitamin when it cannot be synthesised. Vitamins are classified by biological and chemical activity but not by structure.
Vitamin A:
Fat and Water Soluble Vitamins:
Fat soluble vitamins are stored in fat tissues of our body. Water soluble vitamins cannot be stored in body for long time.
- Vitamins A, D, E and K are fat soluble.
- Vitamins C and B are water soluble.
Let Us see them in detail:
Vitamin A:
Vitamin A is a group of "Fat Soluble". Vitamin A is also called retinol. Useful for night vision, healthy skin, digestion, and for developing immune system. It also has an important role in bone growth. It also plays as antioxidants that can cure many cancers.
Food source: Liver, Cod Liver Oil, Carrot, Sweet Potato, Butter, Spinach, Pumpkin, Cheese, Egg, Apricot.
Vitamin B:
These are a group of "Water Soluble" that are very important in Cell Metabolism. In very first research it is only B vitamin later researches revealed there are some other in the same category which are known as Vitamin B1, B2, B3, B5, B6, B7, B9, B12.
Food Source: Yeast, Cereal grains, brown rice, Cauliflower, Potatoes, Oranges, Eggs, Fish, Green beans, Cottage cheese, Milk, Yogurt, Meat, Nuts, Dates, Mushrooms, Legumes, Tomatoes, Broccoli, Royal Jelly, Bananas, Bakers Yeast, Poultry.
Vitamin C:
This comes under "Water Soluble Group". Vitamin C is a very essential nutrient for humans. Ascorbate and ascorbic acid both are there in Human body. Many animals and plants can produce Vitamin C by themselves. This Vitamin C is very helpful for humans in wound healing, functioning of immune system, protects blood vessels, lenses in eyes.
Food Source: Fruits and Vegetables, mainly Oranges.
Vitamin D:
Vitamin D is a group of "Fat Soluble". The Human body can also synthesise this vitamin D in skin tissues. This Vitamin D is in five forms D1, D2, D3, D4, D5. Among these only two are useful for human body they are D2 ( ergocalciferol ) and D3 ( cholecalciferol ).
Vitamin D is useful for immune system regulator, working of brain, maintaining health, recover from tuberculosis.
Food Source: Fatty Fish, Egg, Beef Liver, Mushrooms. Apart from food sources Sun Light is also a good source of Vitamin D.
Vitamin E:
Vitamin E is a group of "Fat Soluble". Among all γ-tocopherol is most common in North American food. It works as an antioxidants, effects in gene expression, enzymatic activity regulator, neurological functions, protects lipids.
Food Source: Kiwi Fruit, Almonds, Avocado, Eggs, Milk, Nuts, Leafy Vegetables, unheated vegetable oils, whole grains.
Vitamin K:
Vitamin K is a group of "Fat Soluble". This provides proteins required for blood coagulation and in metabolic pathways in bone and other tissues. Vitamin K1 can be found in plants, Vitamin K2 can be found in animals, Vitamin K3, K4 and K5 show toxicity.
Food Source: Leafy Vegetables, Avocado, Parsely contain lot of Vitamin K.
Vitamin B:
These are a group of "Water Soluble" that are very important in Cell Metabolism. In very first research it is only B vitamin later researches revealed there are some other in the same category which are known as Vitamin B1, B2, B3, B5, B6, B7, B9, B12.
