chromatography in biochemistry

Chromatography is a laboratory technique used to separate different components of a mixture. In biochemistry, it helps identify and analyze molecules like proteins, DNA, or chemicals. The process involves passing the mixture through a medium (like a gel or paper) that interacts differently with each component. Some molecules move faster, others slower, based on properties like size, charge, or affinity. By collecting and analyzing these separated parts, scientists can study the specific ingredients in complex biological samples, making chromatography a vital tool for understanding biological functions and developing pharmaceuticals.
