biochemical buffer

A biochemical buffer is a solution that helps maintain a stable pH level in biological systems, such as blood or cells. It works by neutralizing excess acids or bases, preventing dangerous shifts in acidity or alkalinity that could disrupt biological processes. Buffers typically consist of a weak acid and its conjugate base or a weak base and its conjugate acid. This balance allows the solution to absorb or release hydrogen ions (H+), the main contributors to pH changes, keeping the environment within a narrow, healthy pH range necessary for proper biological function.
