WebOct 1, 2024 · The solutions contain 20% (200 mg/mL) or 10% (100 mg/mL) acetylcysteine, with disodium edetate in purified water. Sodium hydroxide and/or hydrochloric acid is added to adjust pH (range 6.0 to 7.5). Acetylcysteine is the N-acetyl derivative of the naturally-occurring amino acid, cysteine. Cysteine is a semiessential proteinogenic amino acid with the formula HOOC−CH(−NH2)−CH2−SH. The thiol side chain in cysteine often participates in enzymatic reactions as a nucleophile. Cysteine is chiral. Only L-cysteine is found in nature. The thiol is susceptible to oxidation to give the disulfide derivative cystine, whic…
WebEach side chain is basic (i.e., can accept a proton). Lysine and arginine both exist with an overall charge of +1 at physiological pH. The guanidino group in arginine’s side chain is the most basic of all R groups (a fact reflected in its pKa value of 12.5).
