No, sugar molecules alone do not provide all of the elements needed to make the four types of macromolecules. While sugar molecules (specifically, monosaccharides) are a source of carbon, hydrogen, and oxygen, they do not provide all of the other elements required to make proteins, nucleic acids, lipids, and carbohydrates. These macromolecules require additional elements such as nitrogen, phosphorus, and sulfur that are not present in sugar molecules.
No, sugar molecules do not provide all of the elements needed to make the four types of macromolecules. While sugars (carbohydrates) can provide carbon, hydrogen, and oxygen, they do not contain nitrogen, phosphorus, and sulfur, which are also required to make proteins, nucleic acids, and lipids. These additional elements come from other sources in our diet. Proteins contain nitrogen, lipids contain carbon, hydrogen, and oxygen, and sometimes phosphorus, and nucleic acids contain carbon, hydrogen, oxygen, nitrogen, and phosphorus.
