Biological Macromolecules and Their Functions

This video provides a comprehensive review of macromolecules, also known as organic compounds. It covers the four main types: carbohydrates, lipids, proteins, and nucleic acids. Each section details the monomers, structure, elements, and functions of these macromolecules. Carbohydrates are made of simple sugars and provide energy and support. Lipids, composed of fatty acids, store energy and form cell membranes. Proteins, made of amino acids, facilitate chemical reactions and transport. Nucleic acids, consisting of nucleotides, store genetic information and energy.
