Now, the next question is what do we put at the tyrosine? Well, let's go back to this diagram here, to this experiment number one. So we have tyrosine appearing essentially right over here. And tyrosine, based on experiment one, is attached to lysine. And the only time that lysine appears in this section is right over here. So we conclude that we have glycine tryptophan, then arginine entire scene and then lysine aspartate serene.
