What is the formula for a monosaccharide? Use an example to describe how monosaccharides link to form disaccharides correct answer: (CH2O)*n, where n is the number of carbons and must be greater than 3 (e.g. glucose has 6 carbons, C6H12O6). Glucose and fructose are both monosaccharides, which link through a glycosidic bond to form sucrose, a disaccharide Name, classify and describe the two simplest monosaccharides (3 carbons) correct answer: Glyceraldehyde: Aldo-triose, aldehyde on one end ...
