Which amylase method is described as Saccharogenic and expressed in Somogyi units?

• A. Saccharogenic
• B. Amyloclastic
• C. Chromogenic
• D. Coupled-enzymatic-UV

Answer: (A)

Saccharogenic amylase assay is the one where starch is the substrate and the enzyme’s activity is gauged by the sugars released from starch. Those sugars are reducing sugars, and their amount is measured with the Somogyi reducing-sugar method. Because the readout depends on how much reducing sugar is produced, the activity is expressed in Somogyi units. This contrasts with amyloclastic methods, which track the disappearance of starch itself, chromogenic methods, which rely on color from a substrate fragment, and coupled-enzymatic-UV, which uses a secondary reaction with UV readout.
