Gastric lipase is less active compared to pancreatic lipase because it primarily functions in the acidic environment of the stomach, which is not optimal for its activity. Pancreatic lipase, on the other hand, works in the alkaline environment of the small intestine where it is more efficient in breaking down lipids.
What else can I help you with?
Is the structure of pancreatic lipase the same as gastric lipase?
No, the structure of pancreatic lipase is not the same as gastric lipase. While both enzymes are involved in the digestion of fats, they differ in their amino acid sequences, structural conformations, and mechanisms of action. Pancreatic lipase is more efficient in breaking down triglycerides in the small intestine, whereas gastric lipase functions primarily in the stomach. These structural differences reflect their distinct roles and environments in the digestive process.
Where are gastric lipase made at and were do they work?
Gastric lipase is produced in the stomach by chief cells. It primarily works in the acidic environment of the stomach to break down fats into smaller molecules for further digestion in the small intestine.
What is the substrate of gastric lipase?
The substrate of gastric lipase is dietary triglycerides, which are fats composed of glycerol and three fatty acid chains. Gastric lipase works to break down these triglycerides into smaller components such as diglycerides, monoglycerides, and free fatty acids to aid in digestion.
Which digestive enzymes are active under strongly acidic conditions?
Pepsin is the primary digestive enzyme that is active under strongly acidic conditions, specifically in the stomach where the pH can be as low as 1.5 to 3.5. It is responsible for breaking down proteins into smaller peptides. Additionally, gastric lipase also functions in the acidic environment of the stomach, aiding in the digestion of fats. These enzymes are adapted to operate effectively in the low pH of gastric juice.
What do lipase act on?
lipase is an enzyme that breaks down lipids

These structural differences reflect their distinct roles and environments in the digestive process.
What is the pH of gastric lipase?
The pH of gastric lipase is around 4.0 to 5.0, which is acidic. This acidic environment helps to activate the enzyme and facilitate its function in breaking down fats in the stomach.
What do chief cells do?
Chief cells secret pepsinogen and gastric lipase. Pepsin, the activated form of pepsinogen, can break down proteins into peptides and gastric lipase can break down trigylcerides into fatty acids and monoglycerides.

Where in the alimentary canal does lipase act?
Lipase primarily acts in the small intestine, where it plays a crucial role in the digestion of fats. While a small amount of lipase is produced in the mouth (salivary lipase) and stomach (gastric lipase), the majority of fat digestion occurs in the small intestine, where pancreatic lipase is secreted. This enzyme breaks down triglycerides into fatty acids and glycerol, facilitating their absorption by the intestinal lining.
What is the enzyme responsible for breaking fats into fatty acids and glycerol?
Lipase is the enzyme responsible for breaking down fats into fatty acids and glycerol. It is produced in the pancreas and helps in the digestion and absorption of dietary fats in the small intestine.
What is the active ingredient in gastric juice?
The most important ingredient of gastric juice is hydrochloric acid.
