  • What are the monomer units of the polymer?

    Monomer is defined as a simple molecule with two or more binding sites through which it forms covalent linkages with other monomer molecules to form the macromolecule. Monomers are thus building blocks of polymers.

  • What are the 4 monomer units?

    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.

  • What is polymer in PDF?

    Polymers are made up of smaller repeating units, called monomers, which are linked together by covalent bonds. The polymerization processes by which polymers are synthesized fall into two categories. Addition polymers are formed by addition reactions that link together monomers containing multiple bonds.
  • The four basic polymer structures are linear, branched, crosslinked, and networked.
