Here's a breakdown:
* Carbohydrates: These are made up of simple sugar units called monosaccharides. Common examples include glucose, fructose, and galactose. These monosaccharides can link together to form larger carbohydrates like disaccharides (e.g., sucrose) and polysaccharides (e.g., starch, cellulose).
* Lipids (fats and oils): These are made up of fatty acids and glycerol, not monosaccharides.
* Proteins: These are made up of amino acids, not monosaccharides.
* Nucleic acids (DNA and RNA): These are made up of nucleotides, which contain a sugar (deoxyribose in DNA, ribose in RNA), a phosphate group, and a nitrogenous base. While they contain a sugar, it's not a monosaccharide in the same way as carbohydrates.
