Elastase

Definition

Elastase is a proteolytic enzyme that breaks down elastin, an important protein in connective tissue. It is primarily secreted by the pancreas and plays a crucial role in the digestive process.

5 Must Know Facts For Your Next Test

1. Elastase is produced by the pancreas and released into the small intestine.
2. It specifically targets and hydrolyzes elastin, a protein found in connective tissues.
3. Elastase functions optimally at an alkaline pH, typically found in the small intestine.
4. Inhibitors of elastase can be used to treat conditions where excessive degradation of elastin occurs, such as emphysema.
5. Deficiencies or malfunctions of elastase can lead to digestive issues and complications in nutrient absorption.
