These simple monomers can be linked in many different combinations to produce complex biological polymers, just as a few types of Lego blocks can build anything from a house to a car. As the term suggests, macromolecules are particularly large molecules that contain a lot of atoms. Nucleic acids, macromolecules made out of units called nucleotides, come in two naturally occurring varieties: deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). Why are lipids not considered macromolecules? There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids); each is an important cell component and performs a wide array of functions. Amino acids are the monomers that make up proteins. Make sure you are comfortable identifying statements that are true. MM are relatively immobile, high molecular weight (>3500 DA) compounds that give rise to broad (short T 2) resonances in proton MR spectra of the brain.Failure to account for these macromolecular resonances will generally lead to an overestimation of the metabolite concentrations whose signals overlie the MM signals. In addition to the very important biologic macromolecules (proteins, lipids, polysaccharides, and nucleic acids), there are three major groups of macromolecules that are important in industry. Lipids or fats are the class of macromolecules made up of fatty acids and glycerol. Macromolecules. These include plastics, fibres, and elastomers.
