Biological macromolecules are large molecules essential for life processes. They include carbohydrates, lipids, proteins, and nucleic acids.
These macromolecules consist of sugars and their polymers. They provide energy and structural support to cells.
Lipids are hydrophobic molecules such as fats, oils, and phospholipids. They serve as energy storage molecules and form cell membranes.
Nucleic acids include DNA and RNA. They store genetic information and play crucial roles in protein synthesis and gene expression.
