Explain The Four Macromolecules

The four major macromolecules include carbohydrates, lipids, proteins, and nucleic acids. All four macromolecules are essential for cell structure and function.
Carbohydrates are large molecules that provide energy storage and contribute to cell structure. Carbohydrates can also serve as receptors and aide in cell-to-cell recognition (glycoplids and glycoproteins). This macromolecule is composed of simple sugars called monosaccharides (many sugars = polysaccharides). Examples of carbohydrates include glucose, maltose, and fructose.
Lipids are large molecules that provide energy storage, cell membrane structure, and insulation. This macromolecule is composed of fatty acids. There are two types of fatty acids. Unsaturated fatty acids are double
