What does endogenous enzyme mean?

Enzymes secreted by the animal are called endogenous. Those added in the animal’s feed are called exogenous. Exogenous enzymes are also natural proteins, produced by controlled microbial fermentation, and they work under the same principles as endogenous enzymes.

What are endogenous enzymes in food?

The most relevant plant endogenous enzymes are pectin methylesterase (PME), polygalacturonase (PG), polyphenol oxidase (PPO), and peroxidase (PRO), which are important for fruit and vegetable products.

How many types of enzymes are there?

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

What are exogenous substances?

Endogenous substances are substances that originate within a living organism whereas exogenous substances are substances that originate from outside a living organism. Examples of endogenous substances include cells, tissues, and organs whereas examples of exogenous substances include drugs and medicines.

What are lipase enzymes?

Lipase is an enzyme the body uses to break down fats in food so they can be absorbed in the intestines. Lipase is produced in the pancreas, mouth, and stomach. Along with lipase, the pancreas secretes insulin and glucagon, two hormones the body needs to break down sugar in the bloodstream.

What was used before enzymes?

Enzymes prepared from fungi or bacteria became alternatives to those initially obtained from plants or animals (e. g. amylases and proteases). Purified proteases were used to clarify beer since 1911, pectinases (from various fungi or malt) were used to clarify juices and wine.

What is enzyme classification?

Enzymes can be classified into 7 categories according to the type of reaction they catalyse. These categories are oxidoreductases, transferases, hydrolases, lyases, isomerases, ligases, and translocases. Out of these, oxidoreductases, transferases and hydrolases are the most abundant forms of enzymes.
