A micromolecule is a molecule that is of low molecular weight or relatively smaller than a macromolecule. Some examples are water, minerals, and monomers.
A micromolecule is a tiny molecule characterized by very low weight. These typically link together to create macromolecules, or polymers.
Protein.
A triglyceride is a macromolecule composed of one glycerol molecule bonded to three fatty acids.
Biomolecules contain protoplasm which other molecules do not contain. Micromolecules are with low molecular weight e.g glucose, water. Macromolecules are with high molecular weight e.g starch, protein etc.
molecule having high molecular weight is called macromolecule while a molecule having low molecular weight is called micromolecule
