WebDisulfide bond formation generally occurs in the endoplasmic reticulum by oxidation. Therefore disulfide bonds are mostly found in extracellular, secreted and periplasmic … WebDisulfide bonds also play a significant role in the vulcanization of rubber. In eukaryotes. In eukaryotic cells, disulfide bonds are generally formed in the lumen of the RER (rough endoplasmic reticulum) but not in the cytosol. This is due to the oxidative environment of the ER and the reducing environment of the cytosol (see glutathione). how many words in a 200-page book
