TOPIC.water
Water and ion
solubility
electrons of oxygen
are shared w/
electrons of hydrogen
take energy
out, it freezes
and expands
(lower density:
ice floats in
water)
Will most likely move
till equilibrium is
reached

. fatty acids (hydrophobic) . liposome

. osmosis (aquaporin)
. Concept of water
diffusion
Hydrogen Bonds
Creates Hydrostatic
Pressure, creating
surface tension
* Always will be more water on right side, but
Water level / volume increases on left
side
* new equilibrium is reached when
there's more water on the left side,
to have similar water concentration
* Balanced by hydrostatic pressure
* ions are hydrophilic (water loving)
Hydrophobic
Oil goes to the
top
Triglycerides are formed by a
dehydration reaction of
glycerol and three fatty acids.
The bond connecting the two
is called an ester bond, which
is a type of a covalent bond.
,16,18,20,22 Carbons
All electrons are
equally shared
(no free
electrons)
* uncharged
* carboxylic
3 fatty acids attach
creating 3 ester bonds
Summary:
This carboxylic acid group (from fatty acid) can react with the
hydroxyl in the glycerol to form an ester linkage between the
fatty acid and the glycerol.
, Summary:
two of the three carbons on the glycerol are linked to fatty
acids by ester linkages. The third carbon is linked to a
phosphate by an ester linkage. One oxygen in the phosphate
forms an ester bond with another molecule such as choline,
serine, or ethanolamine.
