Here's how it works:
* Water is added: A molecule of water (H₂O) is added to the large molecule.
* Bonds are broken: The water molecule breaks a chemical bond within the large molecule.
* Smaller molecules are formed: The large molecule is broken into two or more smaller molecules.
Example:
The digestion of starch into glucose is a classic example of hydrolysis.
* Starch (a large carbohydrate) is broken down by enzymes in the digestive system.
* Water molecules are added to the starch molecule.
* Bonds within the starch molecule break, producing smaller glucose molecules.
Other examples of hydrolysis:
* Digestion of proteins into amino acids
* Breakdown of fats into fatty acids and glycerol
* Breakdown of DNA into nucleotides
Key Points:
* Hydrolysis is a catabolic process, meaning it breaks down molecules and releases energy.
* The opposite of hydrolysis is dehydration synthesis, which builds larger molecules from smaller ones by removing water.
* Hydrolysis is essential for many biological processes, including digestion, metabolism, and cellular signaling.
