HUMAN NUTRITION

Detailed explanation-1: -Lipids aren’t polymers since they lack a monomer unit. Simply put, lipids are a type of fat having a glycerol molecule and a two or three fatty acid chain. Although there is always one glycerol, the number of fatty acids varies. As a result, there isn’t a monomer unit.

Detailed explanation-2: -Each different type of macromolecule, except lipids, is built from a different set of monomers that resemble each other in composition and size. Lipids are not polymers, because they are not built from monomers (units with similar composition).

Detailed explanation-3: -The given statement is true. The lipids molecules are not often categorized as polymeric substances since they are do not comprised of monomeric units. The monomers primarily have relevant constituents. The small subunits of a lipid molecule are not bound with each other covalently.

Detailed explanation-4: -The answer is d. All lipids contain fatty acids. The statement that is not true is choice (d) All lipids contain fatty acids. Not all lipids contain fatty acid molecules.
