Enzyme assay

Enzyme assay, I properties of enzyme assays a enzyme assays require measurements of product formation or substrate disappearance over time in order to determine the initial rate.

Transglucosidase units tgu: one transglucosidase unit corresponds to that amount of enzyme that produces 1 μg of glucose in 60 minutes under the conditions of the assay. Introduction enzyme assays have many applications in enzyme kinetics understanding the rates of reactions can help determine the mechanism that the reaction follows. Enzyme assays are among the most frequently performed procedures in biochemistry and are routinely used to estimate the amount of enzyme present in a cell or tissue. Introduction enzyme assays are performed to serve two different purposes: (i) to identify a special enzyme, to prove its presence or absence in a distinct specimen.
