Precursor converted to an active form of a drug within the body.
Industry:Biology; Chemistry
Predicted maximum daily intake of a residue, assuming that it is present at the maximum residue level and that average daily consumption of foods per person is represented by assessed regional diets: it is expressed in milligrams of residue per person per day.

Industry:Biology; Chemistry
Probability of suffering disease or injury that can, for the time being, be tolerated, taking into account the associated benefits, and assuming that the risk is minimized by appropriate control procedures.
Industry:Biology; Chemistry
Probability of the occurrence of a specified undesirable event following exposure of an individual person from a given population to a specified substance at a defined level for the expected lifetime of the average member of that population.
Industry:Biology; Chemistry
Probability unit obtained by adding 5 to the normal deviates of a standardized normal distribution of results from a dose response study.
Note 1: Addition of 5 removes the complication of handling negative values.
Note 2: A plot of probit against the logarithm of dose or concentration gives a linear plot if the response follows a logarithmic normal distribution. Estimates of the LD50 and ED50 (or LC50 and EC50) can be obtained from this plot.
Industry:Biology; Chemistry
Procedure designed to predict the rate of biodegradation of a compound under relevant environmental conditions.
Industry:Biology; Chemistry
Process by which an RNA molecule is used as a template to make a single-stranded DNA copy.
Industry:Biology; Chemistry
Process by which the genetic information encoded in a linear sequence of nucleotides in one strand of DNA is copied into an exactly complementary sequence of RNA.
Industry:Biology; Chemistry
