folate
Vitamins function in the body to aid in energy metabolism.
Riboflavin functions as a coenzyme in energy metabolism. It forms the coenzymes FAD and FMN. These are involved in oxidation/reduction reactions such as those in the electron transport chain and the citric acid cycle. Riboflavin is necessary for metabolism of glucose, fatty acids, and the amino acid tryptophan.
NADH and FADH are Coenzymes which act as carriers of electrons, protons, and energy in metabolism.
The B vitamins are essential for the body's production and use of energy.
Coenzymes are small organic non-protein molecules that carry chemical groups between enzymes.[1] Coenzymes are sometimes referred to as cosubstrates. These molecules are substrates for enzymes and do not form a permanent part of the enzymes' structures.
NADH and FADH are Coenzymes which act as carriers of electrons, protons, and energy in metabolism.
Nutrients important to human metabolism include the essential vitamins and minerals as well as a source of energy that is found in calories from sugar and fats.
Metabolism is best defined as biochemical reactions involved in building cell molecules or breaking down molecules for energy.
Some of the better vitamins for an older person in their 50's are fish oil supplements, B-Complex vitamins for food metabolism/energy, and an overall natural and not synthetic form of a multivitamin.
The cardiovascular system in the human body is involved in energy metabolism by pumping blood throughout the body, which in turn burns energy stored in the body, which in turn speeds up a body's metabolism.
The B vitamins generally have a positive role in energy metabolism. Proper levels of B vitamins in your diet is necessary for proper digestion and the utilization of calories consumed.
In a terse manner, Niacin (B3) is used in the human body to form coenzymes NAD and NADP - two very important components that are involved in energy production. Pellagra is the main deficiency of Niacin.
