Module 5 :
Vocabulary
lipids organic molecule that dissolves in a non-polar solvent
Fatty Acids long carbon shain containing a
carboxylic acid at one end
Saturated no double bonds
unsaturated one or more double bonds
Simplified notation 14 0
: to describe molecule
polyunsaturated fatty contains 2 or more double bonds in a
single fatty acid Chain
acid (PUFA)
Omega system indicates the position of double bonds end opposite of -cont group
Triacylglycerol molecules that store energy
Oil physical state : (liquid) at room temp 25
%
fats physical state : (solid
, Module 5 1 . :
Lipids
lipids :
Molecules serve as the fat molecules in most organisms
energy
·
·
the basis for structure of cell walls
·
some serve as :
-
Vitamins-Vitamin K
-waxes for plants
·
play role in nervous system
nexant
·
Structure is diversed ↑
lipids organic : Molecule that dissolves in non-polar solvent
-
no standard set of compounds
hydrophobic (oils , fats , fatty acids , steriods, fat soluble Vitamins)
share characteristic physical property of non-polar
being
-
Ex) Carotenoid molecules : Possess vibrant colors
-
red color of Cardinal
-
yellow solor of yellow finch /zeaxanthin)
-zeaxanthin (found in pedobacter heparinus)
↳ protects bacterium from harmful effects of wrays .
Experiment :
·
hexane (non-polar solvant)
coconut oil (solid)
3 lipids
·
·
Olive oil Cliquid (
·
Water + food coloring
nexane + coconut oil-solid fat dissolved
H +
20 + 00 =
dissolved
hexane + (0 + 00 + wef) =
does dissolve
Functions :
cell membranes :
·
-
separate life us .
non life
organelle membrane
-
energy storage :
·
fats are most dense form of energy
really hydrophobic they
bic
storage they are
-
water
Push away so
they pack tightly
·
protection :
-
waxes for bees : plants
·
Vitamins :
-
specifically fat.solvable
-
Vitamin k (leaves)
