What are the four types of macromolecules, their bulding blocks, and their main functions?

Carbohydrates: Molecules that provide energy/ fuel and build structures in the body. Example: Sugar. Starch, Cellulose. Building Blocks. Monosaccharides

Lipids:Molecules that store energy and regulate the body's metabolic processes. Building Block: Fatty Acids and Glycerol. Examples: Fats, Steroids, Cholesterol

Proteins: Molecules that provide structural support, cell communication, storage transport, movement, and defense. Building Block: Amino Acids Examples: Enzymes, Structural Components

Nucleic Acids: Molecules that enable living organisms to reproduce genetic information and pass them from one generation to another. Building Blocks: Nucleotides. Examples: DNA and RNA Building Blocks:
