Homocysteine Vitamin B6 Hypothesis...
...Harvard, this thesis also implicates diet, but the villain is protein. Methionine, an amino acid, is broken down by the body into homocysteine, a chemical that promotes atherosclerosis (or the buildup of plaque in the arteries) in lab animals. According to the theory, it is converted by vitamin B6 into an innocuous byproduct, but if there is a deficiency of B6, homocysteine piles up in the blood and causes atherosclerosis. In the view of the theory's proponents, Americans are vulnerable to heart disease because the protective vitamin, which is found in meats, fruits and vegetables is destroyed...
...vitamins are A, D, E, C (ascorbic acid), B1 (thiamine), B2 (riboflavin), Niacin, B6, folic acid, pantothenic acid, and B12. The minerals are calcium, phosphorus, magnesium, iron, iodine and copper...
...four-place Cessna 180 descended toward a landing at Wyoming's Minuteman Missile Site B6. Down and down it went, faster and faster. Too fast. One of the passengers leaned toward veteran Pilot Edgar Van Keuren. The pilot's eyes were open-but sightless. He was dead of a stroke...
...299th try they got a mold that would not grow unless it was fed vitamin B-6 (pyridoxine). The normal mold makes vitamin B-6 for itself. They traced this deficiency to an X-ray-damaged gene that failed to produce the necessary enzyme (organic catalyst) for producing B6. This provided a means of studying genetic changes by corresponding changes in the organism's ability or failure to produce specific chemicals-thus giving genetics a new exactness and turning it into a predominantly chemical science...
