Unit Definition
One USP unit of amylase activity is contained in the amount of Pancreatin that decomposes starch at an initial rate such that 0.16 μEq. of glycosidic linkage is hydrolyzed per minute under the conditions of the assay for amylase activity.
One USP Unit of lipase activity is contained in the amount of pancreatin that liberates 1.0 µEq of acid frim triacetin substrate per minute at a pH of 9.0 and 37° under the conditions of the Assay for lipase activity.
One USP Unit of protease activity is contained in the amount of pancreatin that under the
conditions of the Assay for protease activity
hydrolyzes casein at an initial rate such that there is liberated per minute an amount of peptides not precipitated by trichloroacetic acid that gives the same absorbance at 280 nm as 15 nmol of tyrosine.
Enzyme solution for activity determination
Prepared in 0.2 M phosphate buffer, pH 6.8.
