Which sugar is a monosaccharide with six carbons according to the material?

Explanation:
Six-carbon sugars are called hexoses, and they are monosaccharides. Ribose has five carbons, so it isn’t a six-carbon sugar. Fructose, galactose, and mannose all have six carbons and are hexoses, but the material highlights fructose as the example of a six-carbon monosaccharide. A useful detail is that fructose is a ketose, with the carbonyl group on the second carbon, whereas galactose and mannose are aldoses, with the carbonyl at the first carbon.
