AIPMT-NEET Biology Aspirants, read out the next AIPMT-NEET Biology Study material/ Notes about Vitamins -their major food sources, major functions in human body and what are the diseases related to deficiency of vitamins, important for AIPMT-NEET Biology. Free online notes for AIPMT-NEET.
B-complex Vitamins and Vitamin C are Water-soluble vitamins, while Vitamin A, D, E, K are Fat-soluble vitamins.
|Vitamin||Major Sources||Major Functions in the Body||Deficiency Symptoms/ Diseases|
|Vitamin B1(thiamine)||Legumes, whole grains, potatoes,||Coenzyme in CO2 removal during cellular||Beriberi (fatigue, nerve disorders, anemia), loss of appetite, weakening of heart|
|Vitamin B2 (riboflavin)||Dairy products, meats, enriched, grains, vegetables||Component of coenzymes FAD and FMN||Inflammation and breakdown of skin such as cracks at corners of mouth, eye irritation|
|Vitamin B3 (niacin)||Liver, lean meats, grains, nuts||Component of coenzymes NAD+ and NADP+||Pellagra , inflammation of nerves, mental disorders|
|Vitamin B5 (pantothenic acid)||Liver, eggs, yeast||Part of coenzyme-A, a key connection between carbohydrate and fat metabolism||Loss of coordination; tingling of hands and feet; adrenal problems, reproductive problem|
|Vitamin B6 (pyridoxine)||Cereals, vegetables, meats||Coenzyme used in amino acid metabolism||Irritability, convulsions, muscular twitching, anemia|
|Vitamin B7 (biotin)||Meat, vegetables, legumes||Coenzyme in fat synthesis, glycogen and amino acid metabolism||Loss of hair, Scaly skin inflammation, neuromuscular disorders|
|Vitamin B9 (folic acid)||Green vegetables, oranges, nuts, legumes, whole grains, also synthesized by bacteria in intestine||Coenzyme in nucleic acid and amino acid metabolism||Anemia, birth defects|
|Vitamin B12 (cyanocobalamin)||Red meats, eggs, dairy products, also synthesized by bacteria in intestine||Coenzyme in the production of nucleic acids and in formation of red blood cells||Pernicious anemia, numbness, loss of balance|
|Vitamin C (ascorbic acid)||Citrus fruits, broccoli, tomatoes, cabbage, green peppers||Used in collagen synthesis; antioxidant; improves absorption of iron||Scurvy (degeneration of skin and teeth, breakdown of skin, delayed wound healing|
|Vitamin A (retinol)||Green vegetables, milk products, liver||Component of visual pigments; maintenance of epithelial tissues||Night blindness, flaky skin|
|Vitamin D(calciferol)||Fortified milk, cod liver oil, egg yolk; also synthesized in skin exposed to sunlight||Increases absorption of calcium and promotes bone formation; absorption of phosphorus||Rickets (bone deformities) in children, bone softening in adults|
|Vitamin E (tocopherol)||Whole grains, nuts, seeds||Antioxidant; helps prevent damage to cell membranes; muscle maintenance||Nervous system degeneration|
|Vitamin K (phylloquinone)||Intestinal bacteria, liver, green leafy vegetables||Essential to blood clotting||Blood clotting problems|
