3. glutathione
   The tripeptide g -glutamylcysteinylglycine. It contains an unusual peptide linkage between the g -carboxyl group of the glutamate side chain and the amine group of cysteine. The concentration of glutathione in animal cells is around 5mM and its sulphydryl group is kept largely in the reduced state. This allows it to act as a sulphydryl buffer, reducing any disulphide bonds formed within cytoplasmic proteins to cysteines. Hence, few, if any, cytoplasmic proteins contain disulphide bonds. Glutathione is also important as a cofactor for the enzyme glutathione peroxidase, in the uptake of amino acids and participates in leukotriene synthesis.

7. Glutathione
   Glutathione (GSH) is a tripeptide that contains an unusual peptide linkage between the amine group of cysteine (which is attached by normal peptide linkage to a glycine) and the carboxyl group of the glutamate side-chain. It is an antioxidant, preventing damage to important cellular components caus...

9. Glutathione
   Glutathione (GSH) is a tripeptide and accounts for over 90% of the intracellular non-protein thiols where it functions as an antioxidant and in the activation of T cells. It is especially important in the intracellular removal of the free radical gydrogen peroxide because it provides a substrate for...
