LIFE SCIENCE

Detailed explanation-1: -Proteins. Proteins are the primary building materials of the body. Your hair, skin, muscles, and organs are composed mostly of proteins.

Detailed explanation-2: -The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).

Detailed explanation-3: -Glucose energy is stored as glycogen, with the majority of it in the muscle and liver. The liver uses its glycogen reserve as a way to keep blood-glucose levels within a narrow range between meal times. Some glucose is also used as building blocks of important macromolecules, such as RNA, DNA, and ATP.

Detailed explanation-4: -Proteins are comprised of amino acids. Proteins serve several functions inside living things: Structure of hair, muscle, nails, cell components, and cell membranes.
