Th01L03 Lipids
- Properties
- Glycerol backbone and fatty acid
- Fused via dehydration synthesis
- Ester bond
- Called a triglyceride
- Fused via dehydration synthesis
- Hydrophobic
- Insoluble in water
- Soluble in oil and inorganic solvents
- Insoluble in water
- Glycerol backbone and fatty acid
- Fatty acid
- A long hydrocarbon chain
- Ampiphatic
- hydrophobic and hydrophilic regions
- Hydrocarbon tail
- Carboxylic head
- Hydrocarbon tail
- hydrophobic and hydrophilic regions
- Metabolised via beta-oxidation
pathway to generate ATP
- Types
- Saturated
- Found in meat and dairy products
- Three straight fatty acid chains
- Contains the maximum
number of hydrogens
based on carbons
- Contains the maximum
number of hydrogens
based on carbons
- No double bounds between its carbon atoms
- Examples:
Palmitic acid
C16:0 •
Stearic acid
C18:0
- Found in meat and dairy products
- Unsaturated
- Found in plant oils
- Maybe mono- or polyunsaturated
- Contains one or more double
bonds between its carbon
atoms resulting in non-
straight fatty acids
- Contains one or more double
bonds between its carbon
atoms resulting in non-
straight fatty acids
- Examples • Oleic
acid C18:1 •
Lionleic acid 18:2
- Found in plant oils
- Saturated
- A long hydrocarbon chain
- Biological functions
- Long-term storage
- Adipose tissue
- Fatty acid tails can be release and
broken down into two-carbon units
needed for the TCA cycle
- Adipose tissue
- Phospholipids
- Glycerol plus 2 fatty acids
+ phosphate containing
group
- Example of a glycolipid
- Found in membranes
forming phospholipid
bilayers
- Amphipathic
- Polar (carboxyl) group,
non-polar fatty acid tails
- spontaneously form bi-layer
in aqueous membrane
- spontaneously form bi-layer
in aqueous membrane
- Polar (carboxyl) group,
non-polar fatty acid tails
- Glycerol plus 2 fatty acids
+ phosphate containing
group
- Long-term storage
