Abstract There has been little evidence to indicate that arginine is the natural substrate for generating nitric oxide synthase (NOS) activity. It is now shown that carnosine, which is widely distributed in tissues, is likely to be the true substrate. In tissue sections it gives a stronger NOS reaction than does arginine.
