The two peptides share the copper-tripeptide structure, so a degree of read-across is biologically reasonable but "GHK-Cu does X, therefore AHK-Cu does X" is an inference, not a finding
PKA then phosphorylates and activates hormone-sensitive lipase, the critical enzyme for breaking down stored triglycerides
