Lipids - Coggle Diagram
Lipids
DEFINITION Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells
EXAMPLE Examples of lipids include fats, oils, waxes, certain vitamins (such as A, D, E and K), hormones and most of the cell membrane that is not made up of protein.

INCLUDES
fats, waxes, and some vitamins
TRIGLYCERIDE
WHAT IS IT?
(TG, triacylglycerol, TAG, or triacylglyceride) is an ester derived from glycerol and three fatty acids (from tri- and glyceride)
HOW DOES IT LOOKS?

ESTER BONDS
-
FORMED FROM?They are characterized by a carbon bound to three other atoms: a single bond to a carbon, a double bond to an oxygen, and a single bond to an oxygen.

PHOSPHOLIPIDS
DEFINITION
is a type of lipid molecule that is the main component of the cell membrane. Each of them was made from two fatty acids, a phosphate group, and a glycerol molecule.
-
FUNCTION They surround internal cell and protecting it, they also play a role in cell's structure and function.

EMULSION TEST

HOW TO DO IT?
Just by putting ethanol in the sample, you could know if there's lipids or not. If the sample turns cloudy, then there's lipids in the sample, and if it didn't change, then there is no lipids.
