The biochemistry of NO is complex, and novel insights into the control of NO biosynthesis and mechanisms of signal transduction are continuously emerging. NO is a key regulator of cardiovascular function, metabolism, neurotransmission, immunity, and more, and aberrant NO signaling is a central feature of many major disorders including cardiovascular disease, diabetes, and cancer. Here, we discuss the basics of NO biology emphasizing recent advances in the field including novel means of increasing NO bioactivity with therapeutic and nutritional implications.
