Which enzyme catalyzes the breakdown of triglycerides?

Which enzyme catalyzes the breakdown of triglycerides?

Lipases

Which enzyme is used to catalyze the hydrolysis of triglycerides quizlet?

Lipase catalyzes the hydration of carbon-carbon double bonds of fatty acyl CoA molecules. B). Lipase catalyzes the hydrolysis of ester bonds of triglycerides.

What type of enzyme catalyzes hydrolysis of triglycerides to glycerol and fatty acids?

Lipase Lipases

What type of enzyme catalyzes hydrolysis reactions?

Alkaline phosphatase

Which enzyme is important in the phase 2 reactions?

Phase 2 enzymes traditionally refer to the enzymes catalyzing the conjugation reactions, such as glutathione S-transferase (GST), UDP-glucuronosyltransferase ( UGT), N-acetyltransferase (NAT), and sulfotransferase (SULT).

Which of the following is a phase I reaction?

Phase I reactions are broadly grouped into three categories, oxidation, reduction, and hydrolysis. As most small molecule drugs are lipophilic in nature, drug metabolism converts these hydrophobic compounds into more water soluble compounds that can be excreted. Typically, oxidation is the most common phase I reaction.

Do intravenous drugs go through the liver?

A drug can be metabolized in the gut wall, but most commonly in the liver that is responsible for metabolism before the drug reaches the systemic circulation.

What is a high first pass effect?

Drugs with high first pass effect typically have a considerably higher oral dose than sublingual or parenteral dose. There is marked individual variation in the oral dose due to differences in the extent of first pass metabolism, frequently among several other factors.

What is meant by the first pass effect?

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 are the 7 routes of medication administration?

  • Oral route. Many drugs can be administered orally as liquids, capsules, tablets, or chewable tablets.
  • Injection routes. Administration by injection (parenteral administration) includes the following routes:
  • Sublingual and buccal routes.
  • Rectal route.
  • Vaginal route.
  • Ocular route.
  • Otic route.
  • Nasal route.

What are the six types of enzymes?

The six kinds of enzymes are hydrolases, oxidoreductases, lyases, transferases, ligases and isomerases.

What are the steps of enzyme catalysis?

Four Steps of Enzyme Action

  • The enzyme and the substrate are in the same area. Some situations have more than one substrate molecule that the enzyme will change.
  • The enzyme grabs on to the substrate at a special area called the active site.
  • A process called catalysis happens.
  • The enzyme releases the product.

What do you mean by enzyme catalysis?

Enzyme catalysis is the increase in the rate of a process by a biological molecule, an “enzyme”. Most enzymes are proteins, and most such processes are chemical reactions. Within the enzyme, generally catalysis occurs at a localized site, called the active site.

Does an act of catalysis change enzymes?

In fact, a hallmark property of enzymes is that they aren’t altered by the reactions they catalyze. When an enzyme is done catalyzing a reaction, it just releases the product (or products) and is ready for the next cycle of catalysis.

What are the roles that enzymes play in our body?

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

What is another term for a biological catalyst?

Biological catalysts are called enzymes.

What are the key features of enzymes?

Some characteristics of enzymes are as follows:

  • Enzymes are highly specific for a particular substrate.
  • Enzymes remain unchanged during the reaction itself.
  • Enzymes are very efficient, catalyzing about 1-10,000 molecules of substrate per second.
  • Enzymes do not affect the equilibrium constant, or Keq.

What do all enzymes have in common?

1) They are made up of protein. 2) They do not used up in reaction. 3) They speed up the reaction. 4) They are specific in action.

What is the most important features of enzymatic catalysis?

Like all other catalysts, enzymes are characterized by two fundamental properties. First, they increase the rate of chemical reactions without themselves being consumed or permanently altered by the reaction. Second, they increase reaction rates without altering the chemical equilibrium between reactants and products.

Can enzymes only be used once?

An enzyme can only bind one reactant at a time. An enzyme speeds up a chemical reaction in the cell, but can only be used once.

How do different enzymes differ?

Enzymes differ from ordinary chemical catalysts in several important respects: Enzymes are specific. Usually enzymes catalyze only a single type of reaction, and often they work only on one or a few substrate compounds. Enzymes work under mild conditions.

How does pH affect the structure and function of an enzyme?

The effect of pH Enzymes are also sensitive to pH . Changing the pH of its surroundings will also change the shape of the active site of an enzyme. This contributes to the folding of the enzyme molecule, its shape, and the shape of the active site. Changing the pH will affect the charges on the amino acid molecules.
