LIFE SCIENCE

Detailed explanation-1: -Most macromolecules are polymers, which are long chains of subunits called monomers. These subunits are often very similar to each other, and for all the diversity of polymers (and living things in general) there are only about 40-50 common monomers.

Detailed explanation-2: -A macromolecule, which translates directly to large molecule, is made up of repeating and predictable subunits called monomers. Monomers are smaller molecules that have attachment points on both ends so they can be strung into long chains of a few to several thousand. A polymer are the chains of monomers.

Detailed explanation-3: -The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain (see below).

Detailed explanation-4: -11.1 Introduction: The Four Major Macromolecules These are the carbohydrates, lipids (or fats), proteins, and nucleic acids. All of the major macromolecule classes are similar, in that, they are large polymers that are assembled from small repeating monomer subunits.
