-A disulfide bond joins the sulfur atoms in two adjacent polypeptide chains.
-Permanent wave solution breaks a disulfide bond by adding a hydrogen atom to each of its sulfur atoms.
-The sulfur atoms attach to the hydrogen atom from the permanent waving solution, breaking their attachment to each other.
-Once the disulfide bond is broken, the polypeptide chains can form into their new curled shape. Reduction breaks disulfide bonds and oxidation reforms them.
it is over when you say it is even if there is still CO.VID-19
around 2025 not 2021 still covi.d in 2022 and maybe no cov.id in 2023 but at this rate ther will still be and less c.ovid in2024 no more in 2025 in 4 more year and even thenthere might be a 2end struck
