Here's a breakdown:

* Monosaccharides: These are the simplest form of carbohydrates and cannot be broken down further. They are the building blocks for more complex carbohydrates. Common examples include glucose, fructose, and galactose.

* Disaccharides: These are formed when two monosaccharides bond together. Examples include sucrose (glucose + fructose), lactose (glucose + galactose), and maltose (glucose + glucose).

* Polysaccharides: These are long chains of monosaccharides linked together. Examples include starch, glycogen, and cellulose.

So, to answer your question directly, the monomers of carbohydrates are the individual monosaccharide units that make up larger carbohydrate molecules.
