EVERYDAY SCIENCE

Detailed explanation-1: -The essential chemical components of many enzymes are vitamins, e.g., coenzymes nicotinamide adenine dinucleotide (NAD) and NADP contains vitamin nitacin.

Detailed explanation-2: -Vitamins and minerals are micronutrients required by the body to carry out a range of normal functions. However, these micronutrients are not produced in our bodies and must be derived from the food we eat. Vitamins are organic substances that are generally classified as either fat soluble or water soluble.

Detailed explanation-3: -Coenzymes are organic compounds required by many enzymes for catalytic activity. They are often vitamins, or derivatives of vitamins. Sometimes they can act as catalysts in the absence of enzymes, but not so effectively as in conjunction with an enzyme.

Detailed explanation-4: -Important coenzymes These include two additional redox coenzymes of oxidized nicotinamide adenine dinucleotide phosphate (NADP+) and its reduced counterpart of NADPH, as well as other energy coenzymes like adenosine diphosphate (ADP) and adenosine monophosphate (AMP).

Detailed explanation-5: -The main function of vitamin B3 (also known as niacin or nicotinic acid) is to act as a precursor for the synthesis of two important coenzymes: NAD and NADP.
