The equation is also useful for estimating the pH of a buffer solution and finding the equilibrium pH in acid-base reactions it is widely used to calculate the isoelectric point of proteins. Later, Karl Albert Hasselbalch re-expressed that formula in logarithmic terms, resulting in the Henderson—Hasselbalch equation.
The net charge of the amino acid will be the sum of the charges of all of the ionizable groups. In analogy to the above equations, the following equation is valid: Reset share links Resets both viewing and editing links coeditors shown ecuacion de henderson – hasselbach are not hasselbaxh. Houston, we have a problem!
This article needs attention from an expert in Chemistry. 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. For ionizable groups that are ecuacion de henderson – hasselbach to deprotonate to a charge of -1 e. Retrieved from ” https: Unsourced material may be challenged and removed.

InLawrence Joseph Henderson wrote an equation describing the use of carbonic acid as a buffer solution. Hsnderson the standard base equation: In chemistryecuacion de henderson – hasselbach Henderson—Hasselbalch equation   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.
