WebHowever, like the hydrogen bond, salt bonds are not particularly strong. Ph can break these bonds easily by solid alkaline or acidity. Unlike the physical hydrogen and salt bonds, a disulfide bond is a strong, chemical side bond. Disulfide bonds link the sulfur atoms of adjoining cysteine amino acids to form a single cysteine. WebAug 23, 2024 · 3.3: Cysteine Chemistry. Two cysteine side chains can covalently interact in a protein to produce a disulfide. Just as HOOH (hydrogen peroxide) is more oxidized than HOH, RSSR is the oxidized form and RSH is the reduced form of thiols. When a protein folds, two Cys side chains might approach each other, and form an intrachain disulfide … philips healthcare training center
