Carbohydrate Digestion
This video presents the same text shown beside it, spoken and on screen. It adds nothing the text does not say.
State
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.
Show
Lactase splits lactose into glucose and galactose at the small intestine's brush border.
Watch for
Stomach acid halts amylase activity — carbohydrate digestion pauses through the stomach and resumes only in the duodenum.
