Macromolecules

Macromolecules

Large complex molecules that are essential for life.

Carbohydrates

A group of macromolecules that provide energy and serve as structural components in cells.

Monomer of Carbohydrates

Monosaccharides, such as glucose.

Polymer of Carbohydrates

Polysaccharides, including starch, glycogen, and cellulose.

Function of Carbohydrates

Provide energy; serve as structural components in cells.

Proteins

Macromolecules that catalyze biochemical reactions, provide structural support, and aid in transportation within cells.

Monomer of Proteins

Amino acids.

Polymer of Proteins
