Lipids
Organic compounds that are not soluble in water but are sol uble in oil.
Some examples are:
-Phospholipids
-in the cell membrance, the heads are hydrophilic, the tails are
hydrophobic
-Steroids
-include cholesterol and hormones (cholesterol is also in the ce ll
membrane)
-Fats
Lipids store long-term energy, support cell membrane, cush ion organs,
insulate, help brain develope, etc.
Dehydration Synthesis Applied to Lipids
*This is a saturated triglyceride
When your body has more calories than it needs, it turns the calories to
triglycerides and stores them.
To make a single triglyceride, you need one molecule of glyce rol and
three fatty acid chains.
Water is taken out and the four molecules bind together to fo rm
triglycerides.
Hydrolysis Applied to Lipids
Breaking down lipids with water
1. You ate lipids that need to be broken down to use
2. Your body ran out of carbohydrates and needs to break do wn fat stores
for energy
3500 calories in one pound of fat
Vocabulary
Triglycerides The type of fat our bodies make and store.
Hydrophilic Likes water/faces water.
Hydrophobic Doesn't like water/faces away from water.
Types of Fat
There is saturated fat and unsaturated fat. The saturated/unsaturated part
refers to the amount of hydrogen atoms on one molecule o f fat. There are
two kinds of unsaturated fat, monosaturated fat and polysaturated fat
