Choose the incorrect statement:

Correct answer: D. Glucose has five secondary alcohol groups

  • A. Glucose has one −CHO group
  • B. Glucose has five −OH groups and one primary alcohol group.
  • C. Glucose gives a postive Fehling's solution test
  • D. Glucose has five secondary alcohol groups

Explanation

Glucose is a simple sugar with the molecular formula C6H12O6. It has one −CHO group, five −OH groups and one primary alcohol group. Glucose having -CHO group behaves chemically as aldehydes.So glucose gives a positive Fehling's solution test. A secondary alcohol group is a functional group that has the following structure: R-OH, where R is an alkyl group with 2o carbon glucose does not have any secondary alcohol groups which is clear from its structure given below:

About Macromolecules

Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
