How are polysaccharides and oligosaccharides digested?

Explanation

### Step-by-Step Solution for the Digestion of Polysaccharides and Oligosaccharides

1. **Initiation in the Buccal Cavity**:
- The digestion of polysaccharides and oligosaccharides begins in the buccal cavity (mouth).
- Salivary amylase, an enzyme present in saliva, starts breaking down starch (a polysaccharide) into smaller carbohydrates, primarily maltose and isomaltose.

**Hint**: Remember that salivary amylase is key in the initial breakdown of starch in the mouth.
