Views Read Edit View history. The net charge of the amino acid will be the sum of the charges of all of the ionizable groups. However, these are related by the equation: WikiProject Chemistry may be able to help recruit an expert. The dissociation of water and relative water concentration itself is neglected as well.

La Ecuación de Henderson Hasselbalch

This can be contrasted with a low pK a for an acid, which means that the acid readily dissociates and the molecule is therefore likely to exist as its conjugate base at physiological pH. February Learn how and when to remove this template message. For ionizable groups that are able to deprotonate to a charge of -1 e. Retrieved 27 March Taken together, hasselgach following equation can be used to relate the pH of blood to the concentration of bicarbonate and the partial pressure of carbon dioxide: In chemistrythe Henderson—Hasselbalch equation [1] [2] describes the derivation of pH as a measure of acidity using p K athe negative log of the acid dissociation constant in biological and chemical systems.
