Lipids are not like the other macromolecules we have discussed that are formed from polymerization of specific subunits. Instead lipids are grouped by being_____________
By definition, polymers are macromolecules formed by the combination or interlinking of a single repeating unit i.e. a monomer.
Unlike carbohydrates and proteins, lipids do not form polymers. Lipids consist of a unique starting molecule that is different from the other units.
Lipids are formed by the chemical combination of sub-units through reactions such as dehydration. Fatty acids combine through dehydration and release water.
This process only allow lipids to elongate in one direction only whereas carbohydrates and proteins can form complex, branched structures.
