What else can I help you with?
Does the tongue secrete lingual amylase?
Yes, the tongue secretes lingual lipase, an enzyme involved in lipid digestion, but not lingual amylase. Amylase, which breaks down starches into sugars, is typically secreted by the salivary glands.
What enzymes are in the pharynx?
In the pharynx, the primary enzymes present are salivary amylase (ptyalin) and lingual lipase. Salivary amylase helps break down starches into maltose, while lingual lipase aids in digesting fats. These enzymes begin the process of chemical digestion in the mouth before food travels to the stomach.
Why is gastric lipase NOT as active?
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 is the only macromolecule that gets digested enzymatically in the mouth?
There are two that begin to be digested in the mouth. Sugars by amylase and fats by lingual lipase.
What enzymes are in the mouth?
The saliva in mouth has following enzymes:salivary amylase or ptyalin (breaks down carbahydrates)lingual lipase (enzyme for fats digestion)lysozyme (enzyme that kills bacterial cell)salivary ribonuclease (RNase)Deoxyribonuclease (DNase)
What enzyme digests triglycerides?
Lingual Lipase

What enzyme does hydrochloric acid activate?
Pepsin, in its inactive form it is known as pepsinogen. Lingual lipase, secreted by lingual glands in the tongue, are activated by the acidic environment of the stomach and thus work starts to work after food is swallowed.
Why is gastric lipase NOT as active?
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.

Where is lipase produced?
The simple answer:Lipase is produced in the Pancreas.The technical answer:There are a few different types of lipases; they can be categorized into preduodenal lipases and pancreatic lipases.Preduodenal lipases include lingual lipase and gastric lipase. Lingual lipase is secreted and produced by Ebner's glands (a type of minor salivary gland) located in in moat-like structures around the circumvallate papillae on the tongue. Gastric lipase is produced primarily in the fundus and body of the stomach by chief cells.Pancreatic lipase is secreted and produced by the pancreatic acinar cells and are released by them into the pancreatic ducts. They are contained in zymogen granules and are secreted while still in zymogen granules. Note that there are also other lipolytic enzymes secreted by the pancreas, including colipase.
What breaks up fat during digestion?
Various lipases break up fat. Some produced by the tongue (lingual lipase), a little lipase by the stomach but most by the pancreas (pancreatic lipase). Bile helps to break down fat into little pieces so that the lipases in the small intestine have more surface area to work on.
Enzymes in the alimentary canal?

Why would pancreatic lipase be active in both the mouth and the intestine?
Pancreatic lipase is not active in the mouth. It is produced by the pancreas and released into the small intestine where it helps break down fats into fatty acids and glycerol for absorption. Lipase activity in the mouth is limited as it requires a more neutral pH, which is found in the intestine.
What is found in saliva?
There are three major enzymes in saliva. These enzymes are amylase, Lingual lipase, and Kallikrein. There are four antimicrobial enzymes that help kill bacteria, including lysozyme, salivary lactoperoxide, lactoferrin, and immunoglobulin A.
What food nutrients digested partly in the mouth?
Amylase breaks down starch into dextrin and maltose. Lingual lipase, it doesnt really do much as majority of lipid breakdown occurs after pancreas secretes its bile.
