What is a vitamin? Are there different kinds of vitamins? Why are vitamins important to a person’s daily intake? Well we are about to find out. I have answers to theses questions and others that we will talk about later.
First, what is a vitamin? A vitamin is an organic substance that a person or organism needs as a nutrient in daily amounts. The term vitamin does not include other essential nutrients such as dietary minerals, essential fatty acids, or essential amino acids, and which these are needed in larger amounts than vitamins. (Wikipedia 2012) In words that make sense to me, everyone needs vitamins for their bodies to function properly.
Second, are there different kinds of vitamins? There are thirteen different kinds of vitamins: A, B1, B2, B3, B5, B6, B7, B9, B12, C, D, E, and K. Some of these are fat-soluble vitamins and some are water-soluble vitamins. There were other types of vitamin such as vitamin B4 (adenine), B8 (adenylic acid), F (essential fatty acid), G (riboflavin), H (biotin), J (catechol, flavin), L1 (anthranilic acid), L2 (adenylthiomethylpentose), M (folic acid), O (carnitine), P (flavonoids), PP (niacin), S (salicylic acid), and U (s-methylmethionine). Five of these were reclassified into different kinds of B vitamins, another five of them are naturally synthesized in the body, and the rest are no longer classified as vitamins at all.
The water-soluble vitamins are: vitamin B1 (thiamine), vitamin B2 (riboflavin), vitamin B3 (niacin), vitamin B5 (pantothenic acid), vitamin B6 (pyridoxine), vitamin B7 (biotin), vitamin B9 (folic acid), vitamin B12 (cobalamins), and vitamin C (ascorbic acid). Water-soluble vitamins are vitamins that dissolve easily in water, but are not stored in the body. Therefore, water-soluble vitamins need a consistent intake or daily intake to obtain a healthy body. Some foods that have water-soluble vitamins in them are meat, fish, fruits, vegetables, and dairy products.
The fat-soluble vitamins are: Vitamin A...
