Identify the correct statement.

Options

  1. AAmylose is a branched chain polymer of - D -(+) - glucose units
  2. BLeucine and Tryptophan are classified as Essential amino acids
  3. CCurdling of milk is not a denaturation process
  4. DFructose is an example of Invert sugar

Correct answer

B. Leucine and Tryptophan are classified as Essential amino acids

Step-by-step solution

Amylose is a linear polymer of -D-(+)-glucose units linked by -1,4-glycosidic bonds, not a branched chain polymer. Therefore, the first statement is incorrect. Leucine and Tryptophan are indeed classified as essential amino acids, as they cannot be synthesized by the human body and must be obtained through the diet. Therefore, the second statement is correct. Curdling of milk involves the denaturation of casein protein due to the change in pH caused by lactic acid production, which alters the protein structure.
