Entry, therefore, requires that the xenobiotic have some capaability to penetrate cell membranes.    From Wordnik.com.  [Absorption of toxicants] Reference

Elimination from the body is very important in determining the potential toxicity of a xenobiotic.    From Wordnik.com.  [Excretion of toxicants] Reference

The effect of this enterohepatic circulation is to prolong the life of the xenobiotic in the body.    From Wordnik.com.  [Excretion of toxicants] Reference

Bioactivation is the process by which a xenobiotic may be converted to more reactive or toxic forms.    From Wordnik.com.  [Toxicity] Reference

Thus, reduction reactions frequently result in activation of a xenobiotic rather than detoxification.    From Wordnik.com.  [Biotransformation] Reference

In general, human fetuses and neonates (newborns) have limited abilities for xenobiotic biotransformations.    From Wordnik.com.  [Biotransformation] Reference

Or, in other words, the chemical mixture (of both endogenous and xenobiotic chemicals) can interact with each other.    From Wordnik.com.  [Toxicology of chemical mixtures] Reference

The result is a conjugated metabolite that is more water-soluble than the original xenobiotic or Phase I metabolite.    From Wordnik.com.  [Biotransformation] Reference

Phase II reactions consist of those enzymatic reactions that conjugate the modified xenobiotic with another substance.    From Wordnik.com.  [Biotransformation] Reference

However, if the amount of xenobiotic exceeds the specific enzyme capacity, the biotransformation pathway is "saturated".    From Wordnik.com.  [Biotransformation] Reference

Food ingested at the same time as the xenobiotic may result in a considerable difference in absorption of the xenobiotic.    From Wordnik.com.  [Absorption of toxicants] Reference

Since PCB is a “xenobiotic” that is not found in nature but made only by humans, this is evidence of recent evolution.    From Wordnik.com.  [A Word About Intelligent Design Creationism - The Panda's Thumb] Reference

For a xenobiotic to enter the body (as well as move within, and leave the body) it must pass across cell membranes (cell walls).    From Wordnik.com.  [Absorption of toxicants] Reference

The plasma level of a xenobiotic is important since it generally reflects the concentration of the toxicant at the site of action.    From Wordnik.com.  [Distribution of toxicants in the body] Reference

In this initial step, the potential for a xenobiotic (that is, foreign) substance to induce any type of toxic hazard is evaluated.    From Wordnik.com.  [Risk assessment of chemical substances] Reference

In other cases, the xenobiotic may enter a different biotransformation pathway that may result in the production of a toxic metabolite.    From Wordnik.com.  [Biotransformation] Reference

As a general rule, if a xenobiotic has not been absorbed after passing through the stomach or small intestine, very little further absorption will occur.    From Wordnik.com.  [Absorption of toxicants] Reference

The disposition of a toxicant along with its biological reactivity are the factors that determine the severity of toxicity that results when a xenobiotic enters the body.    From Wordnik.com.  [Toxicokinetics] Reference

Disposition is often used in place of toxicokinetics to describe the time-course of movement of chemicals through the body (that is, how does the body dispose of a xenobiotic?).    From Wordnik.com.  [Toxicokinetics] Reference
