Final answer:
Lingual lipase is an enzyme that breaks down triglycerides, starting the lipid digestion process in the mouth.
Step-by-step explanation:
Lingual lipase is a digestive enzyme produced by glands in the tongue that begins the process of lipid digestion in the mouth. Its primary function is to break down triglycerides into smaller components, which can then be further broken down by other enzymes in the digestive system.
It is important to note that the majority of lipid digestion occurs in the small intestine with the aid of pancreatic lipase, which also targets triglycerides, converting them into two free fatty acids and a monoglyceride.
