What’s the structure of carbohydrates (monomers)

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.

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.
