Detailed explanation-1: -Monomers are the building blocks of the four basic macromolecules of life-monosaccharides are the monomers of carbohydrates, amino acids are the monomers of proteins, glycerol/fatty acids are the monomers of lipids, and nucleotides are the monomers of DNA.

Detailed explanation-2: -For enzymes (and organic molecules in general) the term monomer refers to a single molecule of the compound being considered. If two of these molecules were to interact in such a way as to become linked in a chain while still remaining distinct and identical, they would be a dimer.

Detailed explanation-3: -Amino acids do not have single monomers. They are basic compounds bound to the same molecule, with an amino group and a group of carboxylic acids. Instead, amino acids are monomers of proteins, long chains of amino acids that are bound together by amide bonds.

Detailed explanation-4: -Enzymes are proteins comprised of amino acids linked together in one or more polypeptide chains. This sequence of amino acids in a polypeptide chain is called the primary structure. This, in turn, determines the three-dimensional structure of the enzyme, including the shape of the active site.

Detailed explanation-5: -There are four main types of monomer, including sugars, amino acids, fatty acids, and nucleotides. Each of these monomer types play important roles in the existence and development of life, and each one can be synthesized abiotically.
