The four main classes of organic compounds carbohydrates, lipids, proteins, and nucleic acids that are essential to the proper functioning of all living things are known as polymers or macromolecules. These include proteins, lipids, carbohydrates and nucleic acids. About 30 elements are required by biological systems, including iodine and many metals, though most of these are needed in only trace amounts. The macrominerals na, mg, k, ca, cl, and pare found in large amounts in biological tissues and are present as inorganic compounds, either dissolved or precipitated. Most common elements in living things are carbon, hydrogen, nitrogen, and oxygen. A macromolecule is a very large molecule, such as protein, commonly composed of the polymerization of smaller subunits called monomers. Enzymes are protein molecules that act as biological catalysts. Out of the three macromolecules, the polysaccharides i. Learn vocabulary, terms, and more with flashcards, games, and other study tools.
Chemical elements in biomolecules combining elements into compounds 1. Major elements aside from the big four mentioned above, the next major elements would be phosphorus, sulfur, sodium, chlorine, potassium, calcium and magnesium. Structure and function of macromolecules 1 as we stated in our carbon introduction, the majority of the molecules found in living organisms are based on carbon, along with nitrogen, oxygen and hydrogen in the functional groups. Functional groups commonly found in organic compounds. All compounds can be classified in two broad categories. Pp 3 biomolecules contain the same types of functional groups as do organic. Since macromolecules are generally made up of many smaller molecules and atoms, they are referred to as polymers. This means that they all contain carbon atoms, covalently bonded to the atoms of other elements. The metals in the biological periodic system of the. It presents the latest findings of studies on the molecular structure and properties of proteins, macromolecular carbohydrates, glycoproteins, proteoglycans, lignins. An exception is magnesium, which has a role in rna structure and function.
