The molecular structure of glacial acetic acid is also pivotal in its role in biochemistry. It is a vital component of the metabolic pathways in living organisms. The acetate ion, derived from acetic acid, plays a critical role in the citric acid cycle, which is fundamental in energy production for cellular processes. This indicates that beyond industrial uses, glacial acetic acid is also significant in biological contexts, contributing to the energy needs in biochemical reactions.

Despite its wide range of applications, safety is a crucial aspect when handling glacial acetic acid. It is classified as a hazardous chemical due to its corrosive properties and potential to cause irritation to the skin, eyes, and respiratory tract. Proper personal protective equipment (PPE), such as gloves and goggles, should be used when working with this compound. Furthermore, it should be stored in a cool, well-ventilated area away from incompatible substances to prevent any harmful reactions.

Furthermore, glacial acetic acid assists in the gelation process. Agarose, a polysaccharide derived from seaweed, requires heating to dissolve in the buffer solution. Upon cooling, it forms a gel matrix that serves as the medium for electrophoresis. Adding glacial acetic acid to the agarose solution not only aids in achieving the desired gel concentration but also enhances the gels' mechanical properties. The resulting gel is firm enough to support the nucleic acids while offering sufficient porosity for their separation based on size. This balance is essential because smaller fragments navigate through the gel more easily than larger ones, facilitating effective separation.
