The Interaction of Hemoglobin With Sodium Dodecyl Sulfate in Presence of Ascorbic Acid [PDF]

open access: yesAvicenna Journal of Medical Biochemistry, 2020
Background: Hemoglobin (Hb), oxygen, carbon dioxide, and electron transporter of the body, may enter to an oxidation process that can convert oxyhemoglobin (oxyHb) to methemoglobin (metHb) and hemichrome. Surfactants can facilitate oxidation process that
