Chemical Digestion

Description

Chemical digestion is the process of breaking down complex food molecules into simpler substances through chemical reactions, usually with the help of enzymes and digestive juices. This allows nutrients to be absorbed by the body.

Key points:

• Method: Enzymes and acids break down carbohydrates, proteins, and fats into sugars, amino acids, and fatty acids, respectively.
• Location: Begins in the mouth (saliva), continues in the stomach (gastric juice) and small intestine (pancreatic juice, bile).
• Purpose: Converts food into absorbable nutrients for the body’s use.
