What are lipids are made up of? |
Lipids are made up of monomers called glycerol and fatty acid |
|
|
Draw a triglyceride |
Draw a triglyceride and state how many water molecules are produced via a condensation reaction |
|
|
How many water molecules are produced by a condensation reaction to form a triglyceride? |
Three |
|
|
In a triglyceride what does the R group represent? |
An individual fatty acid |
|
|
In a triglyceride what is attached to each fatty acid? |
A carboxylic acid group |
|
|
In a triglyceride what does the R group consist of? |
The R group consists of a carbon/hydrogen backbone |
|
|
In a triglyceride what does the R group consist of? |
The R group consists of a carbon/hydrogen backbone |
|
|
What is a saturated fatty acid? |
A saturated fatty acid contains all single bonds |
|
|

|
|
What is a saturated fatty acid? |
A saturated fatty acid contains all single bonds |
|
|
What makes the carbon backbone an unsaturated fatty acid? |
It contains a double bond |
|
|
What is the difference between a triglyceride and a phospholipid? |
They are structurally very similar however, one of the fatty acid sidechains is replaced by a phosphate group in a phospholipid. This gives the molecule different properties |

What does hydrophilic mean? |
Hydrophilic means water loving |
|
|
What does hydrophobic mean? |
Hydrophobic means water hating |
|
|
Which part of a phospholipid is hydrophobic and which part is hydrophilic? |
The phosphate head is hydrophilic and so is attracted to water. The tails are hydrophobic and arrange themselves away from water |
