Introduction to biological molecules:
Carbon has the ability to form 4 bons- this allows then to be bonded together to
form more complex molecules.
Carbon acts as a backbone for organis (carbon-containing) molecules found in
all living things.
4 types of biological molecules- carbohydrates, lipids, proteins, nucleic acids
(all based on carbon but some have different things as well).
Carbohydrates- carbon, hydrogen, oxygen
lipid- carbon, hydrogen, oxygen (arranged differently to carbohydrates).
Proteins- carbon, hydrogen, oxygen, nitogen and sometimes sulphur.
Nucleic acids- carbon, hydrogen, oxygen, phosphorous.
Biological molecules contain a large no. of atoms, so they are aka
macromolecules.
Making and breaking polymers:
Monomers- individual molecules that make up a polymer
Polymer- long chains composed of many individual monomers that have been
bonded together.
In carbohydrates:
Monomers- monosacharides
Polymers- Polysaccharides
In proteins:
Monomers and Polymers 1
