Using sulforaphane as the model isothiocyanate, it has indeed been established that its metabolites sulforaphane-glutathione, sulforaphane-cysteine-glycine, sulforaphane-cysteine, and sulforaphane N-acetylcysteine collectively known as dithiocarbamates ( Figure 2 ), are ultimately excreted in the urine (4)
Replenishing the nutritional status of the host by increasing vital amino acids such as cysteine to enhance GSH levels and selenium to improve selenium deficiency and facilitate selenoprotein (GSH peroxidases, thioredoxin reductases) expression can inhibit oxidative stress, modulating inflammation, suppressing endothelial dysfunction, and protecting vascular cells against apoptosis and calcification (He et al., 2017
In prostate and breast cancer cells, palmitoylation occurs at the cysteine residue 797 of the epidermal growth factor receptor (EGFR) residing in mitochondria, which stimulates the activation of EGFR
Glutathione is a natural antioxidant found in all cells of your body
The depletion of glutathione also plays a critical role in the exacerbation of mast cell activation syndrome (MCAS) and dysautonomia, including postural orthostatic tachycardia syndrome (POTS)
