LIFE SCIENCE

Detailed explanation-1: -There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions.

Detailed explanation-2: -Common lipid groups include waxes, steroids, triglycerides, and phospholipids. The function of lipids are very diverse. Some lipids are used to store energy.

Detailed explanation-3: -Proteins, carbohydrates, nucleic acids, and lipids are the four major classes of biological macromolecules-large molecules necessary for life that are built from smaller organic molecules. Macromolecules are made up of single units known as monomers that are joined by covalent bonds to form larger polymers.

Detailed explanation-4: -The four classes of biological macromolecules are proteins, lipids, nucleic acids, and carbohydrates. The monomers of proteins are amino acids. Nucleotides are the monomers of nucleic acids. Lipid monomers are fatty acids and glycerol molecules.
