All cells consist of four organic macromolecules; protein, lipid, carbohydrate (which includes sugar such as starch and glucose) and nucleus acid. Human and animals both consume all these macromolecules, except nucleus acid, as a part of daily nutrients in their diet.
Carbohydrates provide a great amount of energy to us. The carbohydrates are made up of carbon, hydrogen and oxygen. Proteins help in making enzymes, hormones, and in building and repairing of tissues. These proteins are formed by a chain of amino acids linked together. The proteins are bonded by special covalent bonds called peptide bonds. Lipids consist of fats and oil. Our body uses fats to generate energy. Fats from food break down into fatty acids and are used by the body
