endothelial nitric oxide synthase

Endothelial nitric oxide synthase (eNOS) is an enzyme found in the lining of blood vessels called the endothelium. Its main role is to produce nitric oxide, a molecule that helps blood vessels relax and widen, improving blood flow. This process is vital for maintaining healthy blood pressure and preventing blood clots. When eNOS works properly, it supports cardiovascular health by keeping vessels flexible. Factors like exercise, healthy diet, and avoiding smoking can boost eNOS activity, while conditions like hypertension and atherosclerosis may impair it.
