Biological Molecules

What is biochemistry???

Bio chemistryThe study of matter and the changes in matter

Pertaining to life

ProteinsCarbohydrates Lipids

Nucleic Acids

Macromolecules

Polymer: Very large molecule made from individual pieces

MonomerAKA: Subunit

• Hydrolysis: Breaks apart the polymer into monomers

• Water needed to break the bond

• Dehydration Synthesis: AKA: Polymerization

• Links the monomers together to form the polymer

• Produces water

What do monomers look like?• Hydrocarbon: Molecule containing Hydrogen and Carbon

Ethane

Ethene

EthyneUnsaturated

Saturated

Molecular Structure

CHAIN BRANCHRING

Substituted Hydrocarbon

• Hydroxyl -OH• Add –ol suffix to name• Creates an alcohol• Used to disinfect or as a

fuel

Methanol

Methane

• Carboxyl Group -COOH• Creates a carboxylic

acid or organic acid• Found in citrus fruits,

vinegar (ethanoic acid)

Methane

Group Project- Make a Biological Molecule

• Build a biological molecule to hang from the ceiling.

• Include all major structures. • Sketch out model before building. • Be creative!!!
