1. Pancreas: This is the primary source of lipase in the body. The pancreas produces pancreatic lipase, which is secreted into the small intestine.
2. Stomach: The stomach also produces a small amount of gastric lipase, which is primarily active in infants.
3. Tongue: The tongue contains lingual lipase, which starts breaking down fats even in the mouth.
4. Other tissues: Lipase is also produced in smaller amounts by other tissues, such as adipose tissue and the liver.
Summary:
* Pancreatic lipase: Most important source, secreted into the small intestine.
* Gastric lipase: Found in the stomach, active in infants.
* Lingual lipase: Found in the tongue, starts fat digestion in the mouth.
It's important to note that lipase activity can be affected by various factors, including age, disease, and medications.
