Lipids Flashcards
What are Triglycerides
They are a type of energy store which is made of 3 Fatty acids and Glycerol
What are Phospholipids
They are a polymer which help with membrane structure. They contain two fatty acids, glycerol, a phosphate group and a polar group.
How do Triglycerides form?
A condensation reaction forming 3 ester bonds
What are the properties of fatty acids?
4-36 carbons
Has a carboxylic acid end group
Can have double or triple bonds
What does a saturated fatty acid form?
Forms a high density solid (Fat) with a regular structure, also has a high melting point.
What does an unsaturated fatty acid form?
Forms a low density liquid (Oil) with an irregular structure (containing kinks), also has a low melting point.
What is hydrogenation
The addition of hydrogen
How can a unsaturated fatty acid form an saturated fatty acid?
Through the process of hyrogenation
What are waxes?
They are a long chain fatty acids with an alcohol end group, which cannot be digested
