Question

Enzymes secreted by the pancreas are involved in all of thefollowing digestive reactions with one exception. What is theexception?
a) disaccharides to monosaccharides b) proteins to peptides c) triglycerides to monoglycerides and free fatty acids d) starch to maltose
Through process of elimination I got the right answer whichwas (a) but I wanted to know WHY exactly this is correct. DoesAmylase in the pancreas only break down carbohydrate to simplesugar form or does it take it that extra step and break it downinto monomers before absorption?

Explanation / Answer

Amylase (in salivary and pancreatic secretions) only works on thelarge starch polymer. The breakdown of disaccharides requiresspecific enzymes (on the epithelial brush border of the smallintestines) due to the different combination of monomers Maltose --- maltase --> glucose + glucose Lactose --- lactase --> galactose + glucose Sucrose --- sucrase --> fructose + glucose
