Background
Trypsin inhibitors are critical regulatory proteins that modulate proteolytic activity, impacting protein digestion and defense mechanisms. Their precise quantification is essential for assessing nutritional bioavailability and developing anti-inflammatory therapeutics.
Pathways
These inhibitors regulate the proteolytic activation cascade, primarily affecting the conversion of zymogens to active enzymes. This modulation impacts downstream metabolic signaling, extracellular matrix remodeling, and inflammatory response pathways.
