Describe how simple carbohydrates are linked to form complex carbohydrates.

Classify each monosaccharide by using the type of carbonyl group and the number of carbons in the chain. Select the single best answer for each part. Part 1 of 3 Classify ribulose. H H CH₂OH C=0 E -OH OH CH2OH ketotetrose aldohexose Oketohexose O aldopentose ketopentose aldotetrose Part 2 of 3 Classify erythrose. H H OH H -OH CH₂OH aldopentose Oketopentose ketohexose aldotetrose aldohexose O ketotetrose Part 3 of 3 Classify xylulose. CH2OH | =0 HO H H -OH снон O aldopentose aldotetrose ketopentose ketotetrose O aldohexose Oketohexose

1. 2. List which carbohydrates are described as simple and which are complex? Briefly describe the general structures of monosaccharides, disaccharides, and polysaccharides (include the difference between starch and glycogen. Unbranched, occasional branching, and highly branched and how chemical structure effects function). Name the three monosaccharides considered to be important in nutrition, name the three disaccharides commonly found in foods and their component monosaccharides. Then name the foods these sugars are commonly found in (both mono and disaccharides).
