Vitamin B1 (Thiamine)
Vitamin B1 (thiamine) is the precursor of the coenzyme thiamine pyrophosphate (TPP, or thiamine diphosphate, TDP), which fulfils numerous important functions in the body. Vitamin B1 is found in almost all organs and tissues of the body and has a decisive influence on the central and peripheral nervous system, where it is particularly important for signal transmission between nerves and muscles. Vitamin B1 also contributes to nervous system regeneration.
Vitamin B1 is also involved in the metabolism of some neurotransmitters such as acetylcholine and thus contributes to normal psychological function.
Another important area for vitamin B1 is in the extraction of energy from food. TPP, a coezyme, is crucial in the citrate cycle of the mitochondria, where it plays a key role in the aerobic breakdown of glucose.
