Vitamin C Vitamin C, also known as ascorbic acid or L –3 –Ketothreohexuronic acid, is discovered in 1753 by a Scottish naval surgeon named James Lind. It is one of the most important nutrition to the human live yet least understood of all vitamins. The term vitamin is derived from the words vital and amine. Vitamins are organic (carbon-containing) compounds that are necessary for normal physiological functions and cannot be synthesized in adequate amounts. Therefore vitamins must be obtained in our diet. Vitamins are mainly function as catalysts for reactions within the body. A catalyst is a substance that allows a chemical reaction to occur using less energy and time than it would take under normal conditions. Lacking of catalysts, as in vitamin deficiency, will lead to break down of normal body functions and make a person impressionable to disease. The human body is known to need at least 13 different vitamins: 1. Vitamin A (fat soluble) - Retinol; comes from beta-carotene in plants (When you eat beta-carotene, an enzyme in the stomach turns it into Vitamin A.) 2. Vitamin B (water soluble): a. B1 - Thiamine b. B2 - Riboflavin c. B3 - Niacin d. B6 - Pyridoxine e. B12 - Cyanocobalamin f. Folic acid 3. Vitamin C (water soluble) - Ascorbic acid 4. Vitamin D (fat soluble) - Calciferol 5. Vitamin E (fat soluble) - Tocopherol 6. Vitamin K (fat soluble) - Menaquinone 7. Pantothenic acid (water soluble) 8. Biotin (water soluble) (From: http://www.howstuffworks.com/question129.htm) Vitamins come from three sources: Foods, beverages and our own bodies.
