Macromolecules Overview
Macromolecules are large, complex molecules that are essential for life. They are found in all living things and perform a wide variety of functions, including providing structure, energy, and genetic information.
There are four main types of macromolecules: carbohydrates, proteins, lipids, and nucleic acids. Each type of macromolecule has a unique chemical composition and structure, which gives it specific properties and functions.
Types of Macromolecules
Carbohydratesare composed of carbon, hydrogen, and oxygen atoms. They are the body’s main source of energy and are found in foods such as bread, pasta, and rice.
Proteinsare composed of amino acids. They are essential for building and repairing tissues, and they also play a role in metabolism and immunity.
Lipidsare composed of fatty acids and glycerol. They are used for energy storage and insulation, and they also help to form cell membranes.
Nucleic acidsare composed of nucleotides. They store genetic information and are essential for cell division and protein synthesis.
Properties of Macromolecules
