Let's get into a more detailed look at GHK-Cu's components: Glycyl (Glycine, G): The simplest of all amino acids, glycine is a non-essential amino acid and a building block in forming proteins and peptides of low molecular weight like creatine, glutathione, haem, purines, and porphyrins [1]
Additionally, molecular evolution has been used to generate two variants, miniTurbo and TurboID, that have higher activity and allow biotin labeling experiments in the time scale of minutes (Youn et al., 2018)
