Lipids
- Steroids
- Are composed of four rings
of carbon atoms
- Cholesterol, testosterone, estrogen
- Are composed of four rings
of carbon atoms
- Lipids
- Hydrophobic and
water soluble
- All lipids contain large chains
of nonpolar hydrocarbons
- Diverse groups of molecules
that contain regions composed
almost entirely of H ad C
- Hydrophobic and
water soluble
- Fats
- Are used primarly as
energy-storage molecule
- Contains more than twice
as many calories per gram
- Contains more than twice
as many calories per gram
- Solid at room temperature
- Produced primarly by animals
- Structure
- Carbons fatty acids are joined by single bonds
with H atoms at all the other bonding sites
- Carbons fatty acids are joined by single bonds
with H atoms at all the other bonding sites
- Are used primarly as
energy-storage molecule
- Oils
- Structure
- Fatty acids double bonds between some of the
carbons and consequently fewer hydrogens
- Fatty acids double bonds between some of the
carbons and consequently fewer hydrogens
- Are used primarly as
energy-storage molecules
- Contains more than twice
as many calories per gram
- Contains more than twice
as many calories per gram
- Liquid at room temperature
- Kinks prevent oil molecules
from packing closer together
- Kinks prevent oil molecules
from packing closer together
- Found in plant seeds
- Structure
- Unsaturated
- Fatty acids that have double bonds between some
of the carbon and consequently fewer hydrogens
- Fatty acids that have double bonds between some
of the carbon and consequently fewer hydrogens
- Saturated
- Fatty acids that contain as many
hydrogens as possible
- Saturated fatty acid chains are straights and can pack closely
together thus forming a solid at room temperature
- Saturated fatty acid chains are straights and can pack closely
together thus forming a solid at room temperature
- Fatty acids that contain as many
hydrogens as possible
- Waxes
- Form a waterproof coating over the
leaves and stems of plants
- Chemically similar to fats
- Highly saturated meaning
solid at room temperature
- Humans do not have the appropriate
anzymes to break them down
- Highly saturated meaning
solid at room temperature
- Form a waterproof coating over the
leaves and stems of plants
- Phospholipids
- Found in the plasma membrane
that surrounds each cell
- Similar to oils except they have a phosphate group
attached to any of several polar function groups
- Two similar ends
- Two nonpolar fatty acid tails in insoluble water
- Phosphate nitrogen head polar and water soluble
- Two nonpolar fatty acid tails in insoluble water
- Found in the plasma membrane
that surrounds each cell
