You have a 45 year old patient, Mr. Richards that has been suffering from a  digestive disorder since his early childhood.

In the laboratory, you run tests on these samples- a positive buret test indicates that proteins are present, and a positive ninhydrin test indicates that amino acids are present. The table below gives the results for test on the proteases of the patient. Similar results were found for amylases and lipase's from this patient.
