Illustrate metabolic processes of vitamin B
In the human and animal metabolism, they form a functional unit, since, as components of the various coenzymes, they are essential members of reaction chains. They play a part in numerous metabolic processes such as cellular respiration, and energy production, carbohydrate conversion and the synthesis and breakdown of fats and amino acids. Because of their role in energetic metabolic processes, the vitamins are essential for the maintenance of vital processes. Because of this close interdependence and the multiplicity of functions, it is readily understood that the absence of one B complex factor will impair the efficacy of the other vitamins. Therefore, the symptoms associated with vitamin B complex deficiency may be manifold. They mainly affect growth, skin and mucous membranes, blood and nervous system.
