BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Proteins are the building blocks of life. Every cell in the human body contains protein. The basic structure of protein is a chain of amino acids. You need protein in your diet to help your body repair cells and make new ones.

Detailed explanation-2: -Some proteins are fibrous and provide cells and tissues with stiffness and rigidity. These proteins include keratin, collagen and elastin, which help form the connective framework of certain structures in your body ( 13 ). Keratin is a structural protein that is found in your skin, hair and nails.

Detailed explanation-3: -Protein is found throughout the body-in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin that carries oxygen in your blood. At least 10, 000 different proteins make you what you are and keep you that way.

Detailed explanation-4: -Along with fats and carbohydrates, protein is one of the macronutrients we need to live. Our bodies use proteins from food to build and repair tissues, as well as make hormones, enzymes, and other things that are vital to our health.

Detailed explanation-5: -Proteins serve many functions in cells. They act as enzymes that catalyze chemical reactions, provide structural support, regulate the passage of substances across the cell membrane, protect against disease, and coordinate cell signaling pathways.
