PotpourriPts Answer Question50 An aldopentose has this number of stereoisomers.100 These molecules differ in configuration at only one carbon.150 Two aldoses that form the same phenylosazone differ in configuration at this chiral center.200 Vigorous oxidation (using dilute HNO3 and heat) of monosaccarides forms this product.250 Aldoses and ketoses mixed with three equivalentsof phenylhydrazine form these compounds.2. PolysaccPts Answer Question50 Type of bond that holds two simple sugars together.100 Type of glycosidic linkage that occurs in celluloseand starch.150 Humans can’t use cellulose for food because they don’t have the enzyme necessary to hydrolyze thisbond.200 This molecule has been tried as a cancer treatmentand is also known as vitamin B17. 250 This is a nonsugar residue bonded to the anomericcarbon of the acetal form of a sugar.2 1/14/19Carbohydrates3.
