Amylase doesn't catalyze starch, it breaks starch down into simply carbohydrates.  (catalyzes starch doesn't even make any sense, by the way).

Pepsin doesn't catalyze protein, it breaks protein down into peptides for digestive absorption.

So... the difference is that amylase breaks down carbohydrates for digestion while pepsin breaks down protein.

amylase is an enzyme that helps digest carbohydrates. it is produced mainly in the pancreas and the glands that make saliva. when the pancreas is diseased or inflamed, amylase releases into the blood.

in the stomach, the enzyme pepsin functions to break proteins into smaller pieces called polypeptides. because pepsin can only break the bonds next to certain amino acids, proteins are only broken into these shorter chains, and not digested all the way to amino acids.

amylase is the enzyme which acts on starch to produce maltose.
pepsin is the enzyme which acts on proteins to produce peptides.
