Re: Not urgent - arginine
Just for the sake of accuracy, d,l does not mean designed in lab, but refers to mirror image isomers (think of how your hands are mirror images of each other), d being a right handed molecule, l being left handed. D,l arginine would be a mixture of both forms. L-arginine is the useful form, so if using the mixed form, there is less active arginine.
