B vitamins B: Fuel for life, energy and optimal metabolism
B vitamins are a group of eight water -soluble vitamins that play a key role in cell metabolism. Each vitamin performs a unique function, but they all interact closely, supporting the health of the nervous system, brain, heart and other vital organs. Since they are water -soluble, they do not accumulate in the body and should regularly act with food or additives. The disadvantage of even one vitamin group B can lead to various health problems, so it is important to understand their functions and sources. This article will be examined in detail by each vitamin of group B, its role in the body, signs of deficiency, the best sources and potential advantages of taking additives.
B1 (thiamine): a spark of carbohydrate metabolism
Tiamin, also known as vitamin B1, is necessary for carbohydrate metabolism, turning them into energy that cells can use. It plays a vital role in the function of the nervous system, helping to transmit nervous impulses. In addition, thiamine is involved in the synthesis of ATP (adenosine triphosphate), the main energy currency of the cell.
-
Role in the body:
- Metabolism of carbohydrates: Tiamin is a cofactor for several enzymes involved in carbohydrate metabolism, including pyruvatdehydrogenase and alpha-ketoglutaratratodehydrogenase. These enzymes are critical for the breakdown of glucose and release of energy.
