Study Notes

Hydrolysis

  • Hydrolysis is a chemical process that breaks down larger molecules into smaller units by adding a water molecule.

  • Hydrolysis commonly occurs in digestion, where large food molecules are broken down into smaller molecules that can be absorbed by the body.

  • During hydrolysis, a covalent bond is cleaved.

  • Hydrolysis results in the formation of two smaller molecules from a larger molecule. 

Starch

  • Starch is the primary energy storage molecule in plants.

  • Polysaccharides are made up of simple sugars linked together by glycosidic bonds.

  • Polysaccharides are complex carbohydrates that are composed of many sugar molecules.
