These essential biomolecules are obtained out of our dietary sources as our body doesn't produce it at all or seldom does, but it's an obligation that we need to provide them in sufficient quantities on a daily basis for smooth homeostatic and metabolic functions. When they are the biomolecules whose presence in our body shouldn't be compromised with anything else. Universally recognized Vitamins:
