Answer:
Lipids cannot be considered polymers because, unlike carbohydrates, they are constituted of several units that are different.
Step-by-step explanation:
Unlike other biomolecules —such as carbohydrates, proteins and nucleic acids— lipids are not considered polymers because the subunits that form them are different, in addition to being made up of a larger molecule, from which they can grow.
Polymers are formed by repeating subunits, having the possibility of forming and growing at either end of their chain. Polymerization is a characteristic shared by carbohydrates, proteins and nucleic acids, but not by lipids.
Lipids are biomolecules of hydrophobic nature formed predominantly by carbon and hydrogen, whose structure can be linear or forming rings. They have biological importance as they are the main component of cell membranes, reserve energy substrate and form molecules such as hormones.
