Define biological macromolecule Define biological macromolec

Solution

\'Macro\' means \'large\'; a biological macromolecule is a large molecule whose size is greater than 1000 daltons. Proteins and nucleic acids (RNA and DNA) are biological macromolecules of human body.

Molecules whose size is less than 1000 daltons are micromolecules. It is important to note to note that the size of an individual lipid molecule is less than 1000 daltons, still, it is considered a macromolecule. This is because lipids always exist in clusters.
