A vitamin is an organic compound and a vital nutrient that an organism requires in limited amounts. An organic chemical compound is called a vitamin when the organism cannot synthesize the compound in sufficient quantities.Carbohydrates are one of the main types of nutrients. They are the most important source of energy for your body. Your digestive system changes carbohydrates into glucose (blood sugar). Your body uses this sugar for energy for your cells, tissues and organs.Proteins are essential nutrients for the human body.They are one of the building blocks of body tissue, and can also serve as a fuel source
Fat is one of the three main macronutrients: fat, and carbohydrates ,proteins Fats are a wide group of compounds whose basis is in long-chain organic acids, calledfatty acids
VITAMINS: Vitamins are complex chemical substances required by the body in very small amounts. They do not yield energy, but act as catalysts in various body processes. As the vitamins cannot be produced in the body in sufficient quantity, they have to be supplemented through the diet. Vitamins are divided into two groups: (i) Fat soluble vitamins e. g. vitamins A, D, E and (ii) Water soluble vitamins, e. g. vitamins of the B group and vitamin C. Each vitamin has a specific function to perform and deficiency of any particular vitamin leads to specific defi­ciency disease.
