Document Summary
Macromolecule- large molecules that are formed by joining smaller organic molecules together, there are macromolecules that are not used in life, hence biological macromolecules . Polymer-molecules made from repeaing units of idenical or nearly idenical compounds called monomers that are linked together by a series of covalent bonds. Polymers are macromolecules, but macromolecules are not always polymers. Biological macromolecules-large molecules made up of smaller organic molecules. Biological macromolecules are organized into four major categories: carbohydrates, lipids, proteins, and nucleic acids. Carbohydrate-compounds composed of carbon, hydrogen, and oxygen in a raio of one oxygen and two hydrogen atoms for each carbon atom are called carbohydrates. Monosaccharaides-biologically important carbohydrates that have values of n ranging from three to seven are called simples sugars, or monosaccharaides. Lipids-molecules made mostly of carbon and hydrogen that make up the fats, oils, and waxes. Protein-a compound made of small carbon compounds called amino acids.
