1.1 What is polymer?

Basic definitions:

Polymer

Substance composed of molecules which have long sequences of one or more species of atoms or groups of atoms linked to each other primarily by covalent bonds.

Macromolecule

Macromolecule

Giant molecules linked together by monomer molecules through chemical reaction (polymerization)

1.1 What is polymer?

What is polymer?

Polymer in 1920s versus polymer now

Polymers/ macromolecules are in our everyday lives

New substances and recent products from the ingenuity of chemist

Naturally occurring substances used by human beings

Parts of our bodies

Long sequences of one or more species of atoms or groups of atoms (monomer)

Long sequences of one or more species of atoms or groups of atoms (monomer) linked to each other by covalent bond.

Molecular masses ranging from thousands to millions

Polymer derives from Greek terms:

poly = many

mer = meros = parts

Polymerization: The process of linking monomer molecules through chemical reactions

Natural polymer:

Deoxyribonucleic acid (DNA)

One of three major macromolecules (DNA, RNA and protein) for all forms of life .

Two long nucleotide polymers (nucleobases + sugar + phosphate backbone)

These two strands run in opposite directions to each other to form double helix structure

Nucleobases, e.g. thymine (T), adenine (A), cytosine (C) and guanine (G)- are the most basic unit of living organisms.

Contains genetic instructions used in development and functioning of organisms.

1.1 What is polymer?Natural polymer:

Ribonucleic acid (RNA)RNA is made up of a long chain of components called nucleotides. Each

nucleotide consists of a nucleobase, a ribose sugar, and a phosphate group.

The sequence of nucleotides allows RNA to encode genetic information. All

cellular organisms use messenger RNA (mRNA) to carry the genetic

information that directs the synthesis of proteins.

1.1 What is polymer?

Natural polymer:

Protein

Facilitating biological functions.

Basic unit: Polypeptide

A polypeptide is a single linear polymer chain of amino acids bonded

together by peptide bonds between the carboxyl and amino groups of adjacent amino acids.

Typically folded into a globular or fibrous form.
