Witryna17 wrz 2024 · What is a buffer in biology and why is it important? A buffer is a chemical substance that helps maintain a relatively constant pH in a solution, even in the face of addition of acids or bases. Buffering is important in living systems as a means of maintaining a fairly constant internal environment, also known as homeostasis. WitrynaGood set forth several criteria for such buffers: A pKa between 6 and 8. Most biochemical experiments have an optimal pH in the range of 6–8. The optimal buffering range for a buffer is the dissociation constant of the weak acid component of the buffer (pK a) plus or minus pH unit. Solubility in water.
