During the oxidation phase, accumulated ROS (such as hydrogen peroxide HO and superoxide anion O) in the cell can directly react with GSH in a non-enzymatic manner, or, under the catalysis of glutathione peroxidase (GPX), promote the oxidative coupling of two GSH molecules to form one molecule of GSSG, while releasing two protons (H) and two electrons (e)
Sublingual drops sidestep this problem by avoiding the stomach entirely, at least when taken correctly
Moreover, two PLP-dependent enzymes are required to convert homocysteine to the amino acid cysteine in homocysteine transsulfuration pathway: cystathionine -synthase and cystathionine -lyase ( Figure 5 ) (34)
