The new work could shed more light on these issues, says Trinity J. Bivalacqua, an andrology researcher at Tulane University who also studies arginase in human sexual dysfunction. Arginase interferes with a crucial step in the complicated biochemical pathway to sexual arousal, one involving arginine, an amino acid. Normally, the enzyme nitric oxide synthase breaks arginine into citrulline and NO. NO then goes on to relax smooth muscles in the genitalia, allowing blood flow to the area. But arginase foils that by binding arginine and converting it into urea |
