Introduction Iron is an essential trace mineral required for many vital biochemical functions in the human body. It plays a central role in oxygen transport, energy production, and enzyme function. A deficiency in iron can lead to anemia and other health issues, while excessive iron can be toxic. In this answer, we will explore the
Introduction Enzymes are biological catalysts that speed up chemical reactions in the body. Many enzymes require additional molecules known as cofactors to function properly. Two of the most important cofactors are NAD (Nicotinamide Adenine Dinucleotide) and FAD (Flavin Adenine Dinucleotide). These are involved in oxidation-reduction (redox) reactions and are derived from vitamins. In this answer,
Introduction Phosphorus is a vital mineral that plays many important roles in the human body. It is the second most abundant mineral in the body after calcium, and about 85% of it is found in the bones and teeth. The rest is present in cells and body fluids.
