Question

What is the substrate for lipase enzyme?
(a) Protein
(b) Lipid
(c) Carbohydrate
(d) Nucleic acid

Answer 1

Hint: They are water-repelling small molecules that are also included in the substances of building blocks of the body along with others. It is called by several names including fats and triglycerides and their derivatives including cholesterol.

Complete answer:
The substrate of the lipase enzyme is the lipid. The lipase enzyme is responsible for the breakdown of the fatty acids of the triglycerides into smaller subunits that can be dissolved easily and are easily digested.
- Lipase enzyme breaks the molecule of fats by breaking the chemical bonds between them with the help of the molecule of water.
- It plays an important role in the process of digestion, nutrients uptake, and nutrient cycling, and its transportation.
- Their main substrate is a lipid and on the position of its glucose backbone, most of the lipase enzyme acts.
- In the case of humans, the human Pancreatic Lipase (HPL) is the important enzyme that breaks the fats in the digestive system that are consumed through diet and convert it into ingested oils or monosaccharides.
- Sometimes lipase enzyme is secreted by some infectious agents like fungi that may cause infection in the human tissues when they act upon it.
- Lipids are mainly divided into eight categories including fatty acids, triglycerides, glycerolipids, glycerophospholipids, sphingolipids, sterols, prenols, saccharolipids, and polyketides.
So, the correct answer is ‘Lipid’.

Note: The word lipide was derived from the Greek word, meaning fat (lipos) . This term was introduced by the French pharmacologist Gabriel Bertrand in 1923. This word lipide was pronounced as lipid, so it was later named as lipid. The human pancreatic lipase was first discovered by Claude Bernard in 1848 from the pancreatic secretion that could emulsify and then saponify the fatty substances due to the reactions that occur due to an enzyme called HPL.
