Study Notes

Introduction to Macromolecules

Macromolecules are large molecules found in all living things, from bacteria to elephants.
There are four main classes of macromolecules: carbohydrates, nucleic acids, proteins, and lipids.
Nucleic acids, proteins, and carbohydrates are huge molecules, therefore called macromolecules.

Monomers and Polymers

Monomers are smaller molecules that serve as building blocks of a polymer.
When a bond forms between two monomers, each monomer loses a part of the water molecule, releasing a hydroxyl group and a hydrogen atom.
This reaction is repeated as monomers are added to the chain, making a polymer through dehydration or polymerization.

Dehydration Reaction

Dehydration reaction is a process where monomers are bonded together to form a polymer, releasing a water molecule.
This reaction is repeated as monomers are added to the chain, making a polymer.

Hydrolysis

Hydrolysis is the reaction where polymers get disassembled to monomers.
This process is the reverse of the dehydration reaction.
The bond between monomers is broken by the addition of a water molecule, releasing a hydrogen and a hydroxyl group.

Importance of Macromolecules

Inherited differences between close relatives, such as human siblings, are because of small variations in polymers, particularly DNA and proteins.

Biological Processes

Hydrolysis occurs in the process of digestion within our bodies.
Enzymes, which are specialized proteins, facilitate dehydration and hydrolysis reactions in cells.
