What is glucuronic acid conjugation?
The glucuronic acid conjugates, or “glucuronide conjugates” as they are commonly called, are compounds formed by enzyme-catalysed glucuronidation of drug metabolites that contain either a hydroxyl group (ROH – alcohols; PhOH – phenols) or a carboxyl group (RCO2H – acids).
What is meant by biotransformation?
Biotransformation is the process by which a substance changes from one chemical to another (transformed) by a chemical reaction within the body. Metabolism or metabolic transformations are terms frequently used for the biotransformation process.
What is conjugation of a drug?
The combination, especially in the liver, of certain toxic substances formed in the intestine, drugs, or steroid hormones with glucuronic or sulfuric acid; a means by which the biologic activity of certain chemical substances is terminated and the substances made ready for excretion.
Where does biotransformation occur in the body?
The liver is the primary biotransforming organ due to its large size and high concentration of biotransforming enzymes . The kidneys and lungs are next with 10-30% of the liver’s capacity. A low capacity exists in the skin, intestines, testes, and placenta.
What is Glucuronidation metabolism?
n. a metabolic process by which drugs or other substances are combined with glucuronic acid to form more water-soluble compounds, which are more readily excreted by the kidneys or in bile. Glucuronidation is the most prevalent of the Phase II reactions of drug metabolism.
What is the process of conjugation?
Conjugation is the process by which one bacterium transfers genetic material to another through direct contact. During conjugation, one bacterium serves as the donor of the genetic material, and the other serves as the recipient. The donor bacterium carries a DNA sequence called the fertility factor, or F-factor.
How do you conjugate Jeter?
The present participle of jeter is formed with an -ant ending to create jetant. It’s also an adjective, noun, or gerund in certain circumstances. Forming the past tense passé composé is simple. Conjugate the auxiliary verb avoir, then attach the past participle jeté.
What is called conjugation?
Conjugation is the change that takes place in a verb to express tense, mood, person and so on. In English, verbs change as they are used, most notably with different people (you, I, we) and different time (now, later, before). Consider the verb to be and the examples of how it is conjugated into the present tense.
How do you conjugate Celebrer?
How to Conjugate the French Verb Célébrer. In most tenses, the you determine the stem like you would a regular -er verb: Drop the -er off the infinitive, leaving the stem of célébr-. Use the regular -er ending that matches the subject pronoun and tense you’re using.
What is Phase 2 drug metabolism?
Phase I reactions of drug metabolism involve oxidation, reduction, or hydrolysis of the parent drug, resulting in its conversion to a more polar molecule. Phase II reactions involve conjugation by coupling the drug or its metabolites to another molecule, such as glucuronidation, acylation, sulfate, or glicine.
What is the difference between biotransformation and metabolism?
The key difference between biotransformation and metabolism is that biotransformation is a part of metabolism in which the biochemical transformation occurs in a particular drug or compound while metabolism refers to all biochemical reactions taking place in a living organism.
What is the purpose of biotransformation?
The major purpose of biotransformation is to chemically modify (metabolize) poorly excretable lipophilic compounds to more hydrophilic chemicals that are readily excreted in urine and/or bile. Without metabolism, lipophilic xenobiotics accumulate in biota, increasing the potential for toxicity.
What does conjugation mean in medical terms?
Medical Definition of conjugated : formed by the union of two compounds or united with another compound some enzymes are conjugated conjugated bile acids. More from Merriam-Webster on conjugated.
What are the two phases of metabolism?
These are a large family of related enzymes housed in the smooth endoplasmic reticulum of the cell. Metabolism is often divided into two phases of biochemical reaction – phase 1 and phase 2.
Is caffeine a xenobiotic?
Caffeine is one of the most widely used psychoactive drugs in humans, acting as a stimulant, and has been employed as a convenient model xenobiotic in Drosophila research, where it is known to induce the expression of a number of P450 and GST genes in Drosophila S2 cells, larvae and adults [19–22].
What is glycine conjugation?
A number of endogenous and xenobiotic organic acids are conjugated to glycine, in animals ranging from mosquitoes to humans. Glycine conjugation has generally been assumed to be a detoxification mechanism, increasing the water solubility of organic acids in order to facilitate urinary excretion.
What is cytochrome P450?
Cytochromes P450 (CYPs) are a superfamily of enzymes containing heme as a cofactor that function as monooxygenases. In mammals, these proteins oxidize steroids, fatty acids, and xenobiotics, and are important for the clearance of various compounds, as well as for hormone synthesis and breakdown.
What is the meaning of xenobiotics?
Definition. Xenobiotics are chemicals found but not produced in organisms or the environment. Some naturally occurring chemicals (endobiotics) become xenobiotics when present in the environment at excessive concentrations. The “xeno” in “xenobiotics” comes from the Greek word xenos meaning guest, friend, or foreigner.
What is meant by first pass metabolism?
The first pass effect is a phenomenon in which a drug gets metabolized at a specific location in the body that results in a reduced concentration of the active drug upon reaching its site of action or the systemic circulation.
What is metabolism conjugation?
Conjugation. Glucuronidation, the most common phase II reaction, is the only one that occurs in the liver microsomal enzyme system. Glucuronides are secreted in bile and eliminated in urine. Thus, conjugation makes most drugs more soluble and easily excreted by the kidneys.
What is a conjugation reaction?
Conjugation reactions are catalyzed by enzymes known as transferases. D. They involve a cofactor that binds to the enzyme in close proximity to the substrate and carries the endogenous molecule or moiety to be transferred.

What are the phases of biotransformation?

| Hydrolysis | Glutathione conjugation |
| Acetylation | Amino acid conjugation |
Where does Phase 1 and 2 metabolism occur?
The liver is the primary site for metabolism. Liver contains the necessary enzymes for metabolism of drugs and other xenobiotics. These enzymes induce two metabolism pathways: Phase I (functionalization reactions) and Phase II (biosynthetic reactions) metabolism.
