Benedict's reagent is a chemical that is used as a test for the presence of a free aldehyde functional group on glucose. The aldehyde is used when glucose and fructose bind together to form sucrose, and the Benedict's test is negative. Starch contains a great deal of glucose but gives a negative Benedict's test because:
A. all of the aldehyde groups on the starch are oxidized and cannot react with the Benedict's reagent. B. glucose in starch has lost a carbon atom and cannot react with Benedict's reagent. C. only the glucose at the end of a chain of starch will have an exposed aldehyde functional group to react with Benedict's reagent. D. starch is not soluble in water and cannot react with Benedict's reagent.
