Cory-Macromolecules

Macromolecules are large, complex molecules essential to various biological functions. Proteins, composed of amino acids, play versatile roles, including acting as enzymes to catalyze chemical reactions, forming muscles for movement, transporting substances within the body, and serving as hormones like insulin.
