First, we need to convert everything to the same units
With their assistance, cystine is absorbed into cells and rapidly reduced to cysteine, participating in the synthesis of intracellular GSH (Ingold et al., 2018

The review of alpha-linolenic acid: sources, metabolism, and pharmacology
No treatment can honestly promise to erase dark circles, which is why we identify the cause before recommending anything
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]
