Carbohydrate Digestion

what does the intestinal enzyme lactase digest?

lactose (milk sugar)

what does the intestinal enzyme maltase digest?

maltose (malt sugar)

what does the intestinal enzyme sucrase digest?

sucrose (cane/table sugar)

what are disacharrides?

-"double sugars" -a product of the breakdown of starch by digestive enzymes

what are monosaccharides?

-"simple sugars" -a product of the breakdown of disaccharides by the intestinal digestive enzymes maltase, sucrase, and lactase

What do the intestinal digestive enzymes (maltase, sucrase, and lactase) do in the process of carbohydrate digestion?

-digest disaccharides and change them into monosaccharides (simple sugars)

what is the resulting product of maltase digesting maltose?

-glucose

what are the resulting products of sucrase digesting sucrose?

-glucose -fructose

what are the resulting products of lactase digesting lactose?

-glucose -galactose

What are the three intestinal digestive enzymes used in carbohydrate digestion?

-maltase -sucrase -lactase

what are the end products of carbohydrate digestion?

-monosaccharides (simple sugars) -most abundant monosaccharide resulting from this is glucose

what organs do carbohydrate-digesting enzymes come from?

-pancreas and intestines

where does carbohydrate digestion occur?

-small intestine -very little occurs before it reaches small intestine -(salivary amylase has no time to do the job bc we swallow food so fast, and gastric juices contain to carb-digesting enzymes)

what is the role of pancreatic amylase?

-starts the process of carbohydrate digestion in the small intestine -breaks down starches into double sugars, or disaccharides

what is the pancreatic digesting enzyme called?

pancreatic amylase

what are carbohydrates?

starches and sugars
