Phospholipids Flashcards
1
Q
How are Phospholipids produced?
A
Replacement of a fatty acid (acyl) in triacylglycerol by a phosphate group produces phospholipids
2
Q
What are phospholipids?
A
Phospholipids (or phosphoglycerides) are lipids containing glycerol, two long chain fatty acids, and a phosphate group
3
Q
Polarity (hydrophilic, hydrophobic)
A
A phospholipid molecule contains a (hydrophilic) polar head and a (hydrophobic) non-polar tail
4
Q
Polar head of phospholipids
A
The phosphate group is charged 2-, so it can interact with water molecules
5
Q
Non-polar tail of phospholipids
A
1)The carbon chain is non-polar
2)It is hydrophobic and cannot interact with water molecules
