What's the structure of carbohydrates (monomers)

They are a polymer made up from monosaccharides.

If two monosaccharides join together they will make disaccharide.

Their blocks are glucose, fructose and simple sugars.

Carbohydrates are one of the four basic macromolecules of life. They are a polymer made up of monomers called monosaccharides. These building blocks are simple sugars, e. g., glucose and fructose. Two monosaccharides connected together makes a disaccharide.
