Lipase vs. Amylase: What's the Difference?
Edited by Harlon Moss || By Janet White || Published on December 9, 2023
Lipase breaks down fats into glycerol and fatty acids, while amylase breaks down carbohydrates into simple sugars like glucose.
Key Differences
Lipase is an enzyme that specifically targets fats (lipids), breaking them down into glycerol and fatty acids. It plays a crucial role in the digestive system by aiding in the absorption of fats. Amylase, in contrast, is an enzyme that focuses on breaking down carbohydrates, particularly starches, into simpler sugars like maltose and glucose. It is essential in the initial stages of carbohydrate digestion, primarily in the mouth and small intestine.
Produced mainly in the pancreas and small intestine, lipase facilitates the digestion of dietary fats, making them easier to absorb in the intestines. While, amylase is also produced in the pancreas but is notably present in saliva, where it begins the process of carbohydrate digestion even before food reaches the stomach.
In terms of medical significance, abnormal levels of lipase in the blood can indicate issues with the pancreas, including pancreatitis. Elevated or reduced levels of amylase can also signal pancreatic problems, as well as salivary gland disorders or carbohydrate metabolism issues.
Lipase has applications beyond digestion, including in the dairy industry for cheese production and in biotechnology for biodiesel production. However, amylase finds its use in various industries as well, such as in brewing, baking to break down starch in flour, and in the production of biofuels.
Genetically, mutations affecting lipase can lead to disorders in fat metabolism. Similarly, genetic variations in amylase can affect carbohydrate metabolism and have been linked to dietary adaptations in different human populations.

Lipase and Amylase Definitions
Lipase
It plays a crucial role in the digestion and absorption of dietary fats.
Lipase supplements can aid individuals with fat digestion issues.
Amylase
It is primarily produced in the pancreas and saliva.
Amylase levels in blood tests can help diagnose pancreatic disorders.
Lipase
Lipase is an enzyme that catalyzes the breakdown of fats into fatty acids and glycerol.
The doctor measured my lipase levels to assess my pancreatic function.
Amylase
Amylase plays a key role in the initial stages of carbohydrate digestion.
The presence of amylase in the mouth begins the process of breaking down carbohydrates.
Lipase
Beyond digestion, lipase is used in industries like dairy and biotechnology.
Lipase is essential in cheese making for flavor development.
Amylase
Genetic variations in amylase can affect carbohydrate metabolism.
Different levels of amylase production in populations correlate with dietary starch intake.
Lipase
Lipase is produced primarily in the pancreas and the small intestine.
High lipase levels might indicate a problem with the pancreas.
Amylase
Amylase is an enzyme that catalyzes the breakdown of starches into simple sugars.
Amylase activity in saliva kickstarts the digestion of starchy foods.
Lipase
Genetic mutations affecting lipase can lead to disorders in fat metabolism.
Certain genetic conditions affecting lipase production can disrupt normal fat digestion.
Amylase
In industry, amylase is used in brewing, baking, and biofuel production.
Bakers use amylase to convert starch in flour into sugars for yeast fermentation.
Lipase
Any of a group of enzymes that catalyze the hydrolysis of fats into glycerol and fatty acids.
Amylase
Any of a group of enzymes that catalyze the hydrolysis of starch to sugars. In humans, amylases are produced in the salivary glands and the pancreas.
Lipase
(enzyme) Any of a group of enzymes which catalyses the hydrolysis of lipids.
Amylase
(enzyme) Any of a class of digestive enzymes, present in saliva and also contributed to the gut by the exocrine pancreas, that break down complex carbohydrates such as starch into simpler sugars such as glucose.
Egg yolk amylase
Lipase
An enzyme secreted in the digestive tract that catalyzes the breakdown of fats into individual fatty acids that can be absorbed into the bloodstream
Amylase
Any of a group of proteins found in saliva and pancreatic juice and parts of plants; help convert starch to sugar
