macromolecules
large and complex molecules that make up living matter
Macromolecules are large, complex molecules that are made up of smaller subunits called monomers. There are four main classes of macromolecules found in living organisms: carbohydrates, proteins, nucleic acids, and lipids.
Carbohydrates are composed of simple sugars, or monosaccharides, that can be linked together to form more complex molecules such as starch and cellulose. They serve as a source of energy and as structural components of cells.
Proteins are made up of amino acids that are linked together to form long chains. They are involved in a wide range of cellular processes, including enzymatic reactions, structural support, and transport of molecules.
Nucleic acids, including DNA and RNA, are made up of nucleotides that contain a sugar, a phosphate group, and a nitrogenous base. They store and transmit genetic information and play a critical role in protein synthesis.
Lipids are diverse molecules that include fats, oils, and waxes. They serve as a source of energy, insulation, and protection for cells, and are important components of cell membranes.
