Does sugar molecules provide all elements needed to make four types of macromolecules?

No

Explanation:

Sugars provide all the elements necessary for the formation of a macromolecule, carbohydrates. Although sugars can also be found in nucleic acids, their composition depends on other molecules that are not supplied by sugars.

Sugars are the carbohydrate-forming molecules, which are very important in our diet. In fact, the amount of sugar present in carbohydrates, forms classes called monosaccharides (one sugar), osids (hydrolyzable sugars), disaccharides (two sugars) and polysaccharides.

No, If that was the case, then we should only be eating carbohydrates.
