LFS 250 Study Guide - Final Guide: Superoxide Dismutase, Glutathione Peroxidase, Red Blood Cell
Document Summary
Chloride (ion) not chlorine, a poisonous gas: major anionic regulator of ecf volume, essential for stomach acidity, activation of pepsin to digest protein, solubilizing dietary minerals, essential for electrolyte balance and transmission of nerve impulses, supports immune response. Risk/symptom s: minimal risk typically high chloride intake due to high salt (nacl) intake. May be seen with large losses of fluids from body. Food sources: mostly processed, also, added in foods cooking or at the table foods (e. g. , fruits and vegetables) contain little chloride, unprocessed. Protects cell membranes (especially lung cells) and dna from free radicals. Loss of red blood cell membrane integrity causes hemolytic anemia. Loss in contact with heat, light, metals; store in a cool, dark cupboard. Prooxidant; releases the prooxidant iron which can do severe damage. Scurvy: gums bleed and sore, weak, slow wound healing, dry skin, petechiage (hemmoraging on pinpoints of the face) Cofactors for superoxide dismutase which protects against membrane damage in cell membrane and mitochondria.
