Explanation:
Answer:
Polymers are made from a chain of one similar subunit bound together in sequence. Proteins are made from polypepetide chains which are sequences of amino acid subunits. Another example of polymer is DNA and RNA made of nucleic acid subunits.
However, lipids do not have one similar subunit but rather variable ways in which the lipid chains can form. For example phospholipid unit is made of a phosphate molecule bound to a fatty acid chain and glycerol. A triglyceride is a subunit of glycerol bound to three fatty acids chains. Cholesterol is also considered a lipid but is made of carbon rings rather than chains. Lipids therefore cannot be referred to as a polymer.
