Monomers of: Carbohydrates- Glucose Lipids- Fatty acids and glycerol Proteins- Amino acids Nucleic acids- Nucleotides Is an explanation really needed for this because it's really simple to understand?
Common lipid groups include waxes, steroids, fats, and phospholipids. One type of lipid monomer, a fatty acid, consists of one carboxyl group at the end of a linear hydrocarbon containing at least four carbon atoms. Because hydrocarbon chains are nonpolar, fatty acids with long hydrocarbon chains are mainly hydrophobic (insoluble in water) despite having one polar functional group.
