- Condesation reaction
- Phospholipid
- Same as triglyceride but phosphate group replaces 1 fatty acid chain
- Non-polar = insoluble
- Ester bond
- Phospholipid
- Ester bond
- Non-polar = insoluble
- Glycerol + 3 fatty acids
- Phospholipid
- Same as triglyceride but phosphate group replaces 1 fatty acid chain
- Function
- Insulation against heat loss (under skin)
- Protection of internal organs against external forces
- Produce metabolic water (triglyceride) for kangaroos
- Form bilayer in cell membranes (phospholipids)
- Energy storage - yield x2 as much energy in 1g than 1g carbohydrate
- Waterproofing
- Waxy cuticle on plant lead
- Triglyceride
