As a new gaseous signal molecular, H2S has the similar but different mechanisms with carbon monoxide (CO), nitric oxide (NO) in diastolic function forblood vessels, which has several function such as the proliferation of vascular smooth muscle, the dilation of coronary artery, increasing myocardial bloodflow, reducing myocardial oxygen consumption and myocardial protection. CGL is an important endogenous enzyme, which produce H2S in cardiovascular and primarily existed in the vascular smooth muscle, endothelial cells. https://diagnostic-enzymes...
