Question

Upon initial hydrolysis, starch yields:

Options
  • A

    Glucose

  • B

    Maltose

  • C

    Sucrose

  • D

    Mannose

Explanation

When starch is ultimately broken down into glucose molecules, this occurs after further hydrolysis of maltose or other intermediates. The initial hydrolysis of starch yields maltose, not glucose.

When starch is ultimately broken down into glucose molecules, this occurs after further hydrolysis of maltose or other intermediates. The initial hydrolysis of starch yields maltose, not glucose.

Sucrose is a disaccharide composed of glucose and fructose, and it is not a direct product of the initial hydrolysis of starch.

Mannose is a monosaccharide, and it is not a direct product of the initial hydrolysis of starch. The initial hydrolysis of starch yields maltose.
