0 an enzyme (= a chemical substance made by living cells) in saliva, plants, and in the pancreas that helps change starch into sugar

Furthermore, serum amylase was elevated significantly only in the piglets with left-to-right shunts.
Inheritance of a parotid secretory protein in mice and its use in determining salivary amylase quantitative variants.
It is likely that the substrates of amylase in embryos are the starch granules accumulated during development.
Genetic factors on both the second and third chromosomes were responsible for the variation in amylase specific activity and inducibility.
The function of genetic factor(s) on the second chromosome is expected to be the repression of amylase activity in non-induced environments.
The amylases that degrade the starchy endosperm after germination are largely secreted by the aleurone layer after imbibition (see below).
A further interesting observation on the interaction between sugars and amylase gene expression comes from the shrunken-2 (sh-2) maize mutant.
Increased concentrations of salivary gland extracts led to increased amylase activity (fig. 2).
