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 ...

agarose and agar correct answer: polysaccharides used to run DNA gels and for microbial plates bacterial cell walls correct answer: contain polysaccharides in their peptidoglycan layer lectins correct answer: are proteins that bind to sugars protein glycolsylation correct answer: assists in folding and cellular recognition, e.g. ABO blood groups -ose correct answer: indicates a molecule is some kind of carb blood group antigens correct answer: glycoproteins containing differ...
