Carbohydrate Digestion
Captions available
The idea
Carbohydrate digestion starts with salivary amylase converting starch to maltose, continues with pancreatic amylase in the small intestine, and finishes with brush-border enzymes breaking disaccharides into absorbable monosaccharides.
In practice
Lactase splits lactose into glucose and galactose at the small intestine's brush border.
Where people slip
Stomach acid halts amylase activity — carbohydrate digestion pauses through the stomach and resumes only in the duodenum.
