What to Focus On

  • Biomolecules are the chemical basis of life.
  • Metabolism includes anabolism and catabolism.
  • Enzymes control many metabolic pathways.

  • Carbohydrates are classified by hydrolysis, taste, and reducing power.
  • Sugars are sweet and non-sugars are usually tasteless.
  • Sucrose is a non-reducing sugar.

  • Monosaccharides cannot be hydrolysed further.
  • Aldoses and ketoses are the two major types.
  • D and L denote configuration only.

Common Mistakes to Avoid

Sucrose is a reducing sugar because it is a carbohydrate and contains glucose and fructose.

Amylose is the branched part of starch and amylopectin is the linear part.

Glucose must give 2,4-DNP test and Schiff's test because it has an aldehyde group.

Memory Tips
