Nitric oxide (NO) is an ubiquitous free radical gas, which acts as a general plant signal during growth and development and stress responses. Nitric oxide – (NO) has many functions in the body but the focus of this article is nitric oxide’s function as a signaling molecule that relaxes the small muscles in our blood vessels, allowing increased blood flow through the vessel (in other words, NO is a vasodilator). NO is one of the factors that plays an important role in control of vascular tone, mean arterial pressure (MAP) and heart rate (HR) (Musialek et al.

It modulates immune function, blood vessel dilatation and neurotransmission. Recent evidences suggest that NO may act as an endocrine molecule. High intensity interval training (at 85% to 90% of VO2max) is more effective in improving endothelial function and nitric oxide availability than continuous moderate aerobic exercise. Accumulating evidence suggests that mitochondrial activity can be modulated by nitric oxide (NO). Epub 2012 Feb 16. Nitric oxide is produced when the nitric oxide synthase enzyme converts the amino acid L-arginine into L-citrulline and nitric oxide as products. The biochemistry and physiology of S-nitrosothiols. NIH Nitric oxide is a compound in the body that causes blood vessels to widen and stimulates the release of certain hormones, such as insulin and human growth hormone. Keywords: arginase, nitric oxide, citrulline, arginine, diabetes, vascular function. Existing data suggest the idea that NO is a hormone that after production in tissues, it is stabilized and transported as nitrite and/or S-nitrosothiols in the blood to target cells. Because it boosts nitric oxide levels, it can prevent constriction as well. The possession of intestinal bacteria that make NO enables Caenorhabditis elegans to live for significantly longer than members of its species without the bacteria.C. Gastric function is largely regulated by an (1) excitatory (cholinergic) and inhibitory (nitric oxide (NO)/nitrergic) neurotransmitters working directly on smooth muscles or electrical signals that originate from the interstitial cells of Cajal (ICCs) .  |  Bodybuilders and other athletes take NO … Essentially, the hormone switches genes on and off, changing the way that cells function. 2012 May;3(5):522-7. doi: 10.1039/c2fo10206d.
