B Vitamins

Here's a list of B vitamins, with their associated names, for my own reference (since I tend to forget these easily). The ones crossed out are no longer considered "true" vitamins. All the B vitamins are water-soluble. The common (accepted) ones are in bold.

"B" Name	Real Name	Purported Purposes
Vitamin B-1	Thiamine	B-1 helps the cells convert carbohydrates into energy. Supposedly also helps keep mosquitoes away, but this is apparently unconfirmed and most likely just urban myth. Is essential for the functioning of the heart and for healthy nerve cells, including those in the brain. Also helps the body cells convert carbohydrates into energy.
Vitamin B-2	Riboflavin	Body growth and red blood cell production. Similar to thiamine, it helps in releasing energy from carbohydrates.
Vitamin B-3	Niacin	Niacin is often prescribed by doctors to help reduce LDL (bad) cholesterol levels. Also helps maintain healthy skin and nerves. It is also important for the conversion of food to energy.
Vitamin B-4	Adenine	???
Vitamin B-5	Pantothenic acid	Metabolism of food, synthesis of hormones and cholesterol. Apparently helps clear up acne, as well.
Vitamin B-6	Pyridoxine	Helps the body use ingested protein, aids in the formation of red blood cells and in the maintenance of normal brain function. It also assists in the synthesizing of antibodies in the immune system.
Vitamin B-7	Biotin	Metabolism of proteins and carbohydrates, synthesis of hormones and cholesterol.
Vitamin B-8	Ergadenylic acid	RNA synthesis, as well as ADP and ATP synthesis. Helps break down food into energy and supports hormone functions.
Vitamin B-9	Folic acid	Synthesis of DNA, production of red blood cells, and prevention of birth defects.
Vitamin B-10	Para-aminobenzoic acid (PABA)	Protects the skin against ultra-violet radiation. Also helps with the breaking down of protein, and maintaining intestinal flora.
Vitamin B-11	Pteryl-hepta-glutamic acid	???
Vitamin B-12	Cyanocobalamin	Important for metabolism, formation of red blood cells, and maintenance of the central nervous system.

Inositol and Choline Bitartrate are also related to the B vitamin family (inositol is sometimes dubbed vitamin B_m). Choline is good for enhancing memory and brain function. Inositol is used for the breakdown of fats and reducing blood cholesterol.
