Lipids 2: Phospholipids and cholesterol

?
Describe the structure of a phospholipid?
A glycerol with 2 fatty acids and a phosphate group.
1 of 5
What happens when a surrounded by water?
As the tail is hydrophobic and the head, hydrophilic, phospholipids will form a sphere(micelle)
2 of 5
Explain the difference between a Triglyceride and a phospholipid
a phospholipid has a phosphate group that replaces one of the fatty acid tails on a triglyceride.
3 of 5
How does the presence of a phosphate group affect the properties of a glyceride?
It makes one end of the glyceride polar, which makes it attract water. The fatty acid end of the glyceride remains non-polar
4 of 5
What reaction occurs when a phosphoric acid molecules react with glycerol?
Condensation
