Is cysteine ionizable
WebMar 6, 2024 · Cysteine (Cys/C) is the only amino acid with a sulfhydryl group in its side chain. It is nonessential for most humans, but may be essential in infants, the elderly and individuals who suffer from certain metabolic diseases. Cysteine’s sulfhydryl group is readily oxidized to a disulfide when reacted with another one. WebA reducing environment is one that is rich in electrons, but this is relative to the electronegativity of the atom in the molecule. Oxygen is very electronegative and tends to …
