Study Notes
Chemical Bonding
- Substances that do not form polar bonds are likely to be non-polar
- A molecule with a large number of polar covalent bonds is likely to be polar
Proteins
- Proteins have various functions inside cells
- The function of proteins inside cells is not specified in the given information
Carbohydrates
- Sucrose is NOT a monomer (it is a disaccharide)
- Hydrolysis is the breaking of molecular bonds, releasing water
Glycoproteins
- Glycoproteins are mainly found on the surface of cells
- Glycoproteins are proteins with carbohydrate molecules attached
Lipids
- Triacylglycerols are a type of lipid, also known as triglycerides
- They are composed of glycerol and three fatty acid chains
Peptide Chains
- The beginning of a peptide chain is called the amino terminus
- The end of the peptide chain is called the carboxyl terminus
Polymerization
- Long polymers are made from single subunits in cells using a condensation reaction
- This reaction releases water molecules
