Question

Lingual lipase which can digest 30% of dietary triglycerides is released by

• A. Stomach
• B. Pancreas
• C. Liver
• D. Dorsum of the tongue

Answer 1

The correct option is D Dorsum of the tongue

Lingual lipase release is signaled by autonomic nervous system after ingestion, during which the serous glands under the circumvallate and foliate papillae on the surface of the tongue secrete lingual lipase to the grooves of the circumvallate and foliate papillae. The hydrolysis of the dietary fats is essential for fat absorption by the small intestine, as long chain triacyglycerides cannot be absorbed, and as much as 30% of fat is hydrolyzed within 1 to 20 minutes of ingestion by lingual lipase alone.
