182 Lecture 5 Lipids
Hydrocarbon with Oxygen = Hydrophobic
Assembled via dehydration reactions – fatty acid + Glycerol
STRUCTURE
Methyl – Hydrocarbon chain – acid group
Saturated
- No double bonds
- Packed together
- Solid at room temperature
Unsaturated
- 1 (monounsaturated) or more (polyunsaturated) double bonds
There are variations of fatty acids based on the length of the hydrocarbon chain
...
Hydrogenated and trans fatty acids
Unsaturated fat synthetically converted to saturated by adding Hydrogen
- CIS = H on the same side attached to double bonded carbons – found in nature
- TRANS= H on different sides attached to double bonded carbons – manufactured
Functions
Fat
- Long term food storage in adipose cell,
- Cushioning of organs
- Insulation (subcutaneous fat)
Fatty acid
- Energy storage
- Building blocks of phospholipids and glycolipids
- Targeting Molecules
o Attached to proteins – can direct protein to appropriate place
- Messenger molecules
o Hormone and intracellular messenger molecules
Phospholipid
Phosphate group attached to Ester linked carbon chains
- Phosphate group= hydrophilic head
- Carbon chain = hydrophobic tail
- Form the phospholipid bilayer
o Allow through: gases, hydrophobic molecules, sml polar molecules (H2O)
o Doesn’t allow through: lrg polar molecules, charged molecules
Glycolipids
Cell to cell communication markers and provide energy
