CM 9092 House rules
Please bring your clicker and scientific calculator at all time!
Class attendance is NOT mandatory. You may not attend classes at your own risk.
You shouldn't be late, but if you must be late, come in as quietly as possible and sit near the door.
All mobile phones in silence mode.
No chit chat in the class. Don't say anything to anyone at any time unless, during Q&A time. If you want to talk, please leave the class.
You may sleep during lecture(s). But please do NOT snore, i.e. please do not disturb others.

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.
