Hello, everyone! Could you define in chemical terms, what are the macromolecules? In terms of molecular weight and maybe chemical structures (scaffolds, cyclic parts and etc.)? 🧐

A macromolecule is a molecule with a high molecular weight, the structure of which is represented by multiple repetitions of units formed (in reality or mentally) from molecules of low molecular weight. The number of atoms that make up macromolecules can be very large (hundreds of thousands and millions). Substances with a molecular weight of more than 103 Da are usually considered high molecular weight. Whether the molecular weight is large enough for a molecule to be considered a macromolecule can often (but not always) be determined by the following criterion: if the addition or removal of one or more units does not affect the molecular properties, the molecule can be considered a macromolecule (such a criterion fails, for example , in the case of biopolymers).
