Question

what is the name of the sugar that is composed of only one molecule of sugar?
monomer
polysaccharides
disaccharide
monosaccharide

Explanation:

Monosaccharides are the simplest form of carbohydrates and are composed of a single sugar molecule. Examples include glucose, fructose, and galactose. Polysaccharides are made up of many monosaccharide units (e.g., starch, cellulose). Disaccharides consist of two monosaccharide units (e.g., sucrose = glucose + fructose). A monomer is a general term for a single unit that can form polymers (not specific to sugar).

Answer:

monosaccharide
