What molecule do dietary nitrates convert into to signal vasodilation?
Answer
Nitric oxide
Dietary nitrates, abundant in beets, are crucial compounds that the body metabolizes. This conversion process results in the formation of nitric oxide. Nitric oxide functions as a signaling molecule within the circulatory system, specifically targeting the smooth muscles that surround blood vessels. Its primary action is to induce relaxation and widening of these vessels, a physiological process termed vasodilation. This vasodilation is directly responsible for improving overall blood flow efficiency and achieving a clinically significant reduction in both systolic and diastolic blood pressure readings shortly after consumption.
