👉 Tetrameric is a term used in physics and chemistry to describe a system where two or more molecules are held together by shared bonds between them. This type of system is often referred to as a "tetramer" because it can be formed from any number of molecules, with each molecule sharing the same set of shared bonds. In terms of chemistry, tetrameric systems are commonly found in organic compounds where they are used to make polymers, such as polyethylene terephthalate
