Step-by-Step Analysis
The question asks you to match six carbohydrate-related terms with their definitions or descriptions from the provided answer options. We are given the correct matches in the 'answer' list in order for items 1 through 6. The full set of potential definitions is shown in 'answer_options', and you should pair each item with the option that best fits the corresponding term. Item 1 corresponds to aldaric acid. The correct match in the answer list for item 1 is the first option: 'modified sugar with terminal dicarboxylic acids'. This makes sense because aldaric acids are products of oxidation of both ends of an aldose, forming carboxyl groups at both ends, i.e., terminal dicarboxylic acids. Other options here would not describe a sugar with two terminal carboxyl groups (for examp......Login to view full explanation

Determine if each of the following is True or False:   True Acetals of sugars only open to carbonyls in acidic conditions so are non-reducing. True Hemiacetals and acetals are more reactive in acidic conditions than alcohols or ethers. True It is possible to selectively form or break bonds at the anomeric carbon vs. other carbons in a carbohydrate. True Reactions in basic conditions will tend to keep the stereochemistry of the anomer, while reactions in acidic conditions will tend to mix the stereochemistry of the anomer. True Alcohols in carbohydrates form ethers analogously to simple alcohols. False Reducing sugars are always ketoses.
