FSY tripeptide – Other Categories

Angiotensin I-converting enzyme (ACE) plays a critical role in blood pressure regulation. There is a rise in conditions linked to hypertension such as heart attacks, strokes, and dementia. This has led to search for novel inhibitors of ACE to regulate blood pressure. Food-derived bioactive peptides have been identified and utilised for their health-promoting abilities. The tripeptide FSY (Phe-Ser-Tyr) was identified from shrimp (Pandalus borealis) protein hydrolysate as a highly potent inhibitor of ACE activity. FSY is capable of being absorbed in the digestive tract to be transported in the blood to the receptors which is a useful feature for clinical application. Further study can provide deeper understanding of FSY potency on ACE function and may lead to drug development.
