Question

Which of the following is correct for gastric lipase in stomach?
A) It changes lipids of glycerol
B) It changes lipids into fatty acids and glycerol
C) It has effect on proteins
D) None of the above

Answer 1

The stomach is a muscular organ which is located on the upper left side of the abdomen. The stomach contains a hydrochloric acid which helps in digestion of food. The stomach receives the food from the esophagus.

Complete answer:
Lipase: Lipase is an enzyme which breaks down the triglycerides into glycerol and fatty acids. Lipases are responsible for fat digestion.
Gastric lipase: Gastric lipase is also called the LIPF because it is encoded by the LIPF gene. Gastric lipase is an acidic lipase and it is secreted by the gastric chief cells of the stomach. It is secreted in the fundic part of the stomach.The pH of gastric lipase is between 3-6. The function of gastric lipase is that it changes the lipids or triglycerides into fatty acids and glycerol. Gastric lipase hydrolyzes the ester bonds of triglycerides in the stomach. These enzymes are found in the cytoplasm and the cell membrane of the gastric cells.
Therefore, it has been clear from the above discussion that gastric lipase can change lipids into fatty acids and glycerol.
Hence, option B is the correct answer.

Note: Gastric lipase can compensate for the decrease in production of pancreatic lipase. Decrease in production of pancreatic lipase is due to the improper functioning of the pancreas. Gastric lipase is a polypeptide of 371 residues. The structure of gastric lipase was determined by the Xray diffraction.
