The first and rate-limiting step of GSH synthesis is catalyzed by glutamate-cysteine ligase, which is regulated by cysteine availability at the level of transcription and translation 6

Its research profile makes it relevant for studies focused on GHRH receptor activity, GH pulse dynamics, pituitary response, IGF-1 signaling, metabolic regulation, and age-associated endocrine pathway models

For example, studies suggest that GHK is present in the alpha 2(I) chain of type I collagen , which suggests that the tripeptide might be liberated by proteases at the site of a wound and exert in situ healing
