GCL is specific for the glutamyl moiety and is regulated physiologically by: (a) non-allosteric feedback competitive inhibition by GSH (Ki=2.3mM), which involves binding of GSH to the glutamate and another site on the enzyme [8, 9] and (b) availability of its precursor, cysteine [1] .The apparent Km values of GCL for glutamate is 1.8 mM, and for cysteine and 0.10.3 mM [9]

Although individual peptides have been investigated in various controlled studies, clinical data on the combined blend is limited, and further human trials are needed to establish efficacy and optimal dosing protocols

Amino acid analysis provides the most accurate concentration determination for peptides without chromophores

Thanks to its low self-pay prices, the Wegovy pill also tends to cost less than many other GLP-1s, including Zepbound and Saxenda
