Sucrose is a non-reducing sugar.
Only monosaccharides can be absorbed in the small intestine. Disaccharides are hydrolyzed first by brush border enzymes.
Isomaltase cleaves a-1, 6 branch points.
α-Amylase is secreted by both the pancreas and the parotid gland.
Bacterial cell walls contain a heteropolysaccharide consisting of alternating N-acetylglucosamine + N-acetylmuramic acid residues.
Hyaluronidase splits hyaluronic acid:
■ Promotes depolymerization
of ECM
■ Lowers HA viscosity and
increases CT permeability

Cariogenic bacteria synthesize glucans (dextrans) and fructans (levans) from their metabolism of dietary sucrose, which aid in their adherence to teeth.
von Ebner’s salivary glands are serous. Located in circumvallate papillae of tongue.
