Macromolecule is a term used to describe large molecules, such as proteins, carbohydrates, and nucleic acids, that are made up of smaller molecular units. Understanding the structure and function of these molecules is important in fields such as biochemistry, molecular biology, and biotechnology. Being skilled in macromolecule analysis involves knowledge of techniques such as gel electrophoresis, chromatography, and spectrophotometry, as well as an understanding of how macromolecules interact with each other and with their environment.
