Structure & Function of Lipids Flashcards
1
Q
What are lipids made of?
A
triglycerides
2
Q
What is the function of triglycerides?
A
energy storage
3
Q
What is the structure of triglycerides?
A
long polymers - lots of bonds
insoluble - don’t affect the water potential and no effect on osmosis
form insoluble droplets - hydrophobic tails on inside
4
Q
What are the parts of the phospholipids?
A
glycerol molecule
phosphate head (hydrophilic)
ester bonds connecting glycerol to fatty acids
fatty acid tails (hydrophobic)
5
Q
What is the function of phospholipids?
A
they form cell membranes - which controls what goes in / out of cells
phospholipid bilayer - cell membrane
hydrophobic tails face inwards
the middle is hydrophobic - it makes it difficult for polar H2O to differ into
