PY - 2023 T2 - Fishman’s Pulmonary Diseases and Disorders, 6e AB - Regulation of [H+] is of crucial importance for maintenance of normal cellular functions. The normal [H+] is maintained at about 40 nEq/L. When there is even a small change in the [H+], intracellular proteins gain or lose H+ ions resulting in alterations in charge distribution that may affect molecular structure and protein function. The hydrogen ion concentration in bodily fluids is largely regulated by the ratio of the concentrations of carbon dioxide and bicarbonate. This is predicated upon the relationship demonstrated in the Henderson–Hasselbalch equation: SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/16 UR - accessmedicine.mhmedical.com/content.aspx?aid=1194946749 ER -
