What is a group of organic compounds including fats, oils, phospholipids, and steroids
lipids
-
One of the building blocks of a fat molecule
fatty acid
-
The organic compound building block for fat molecules
glycerol
-
The single carbon-carbon bond, links all carbon atoms
saturated fatty acid
-
One or more double bonds
unsaturated fatty acids
-
Type of organic molecule including complex rings of carbon and hydrogen atoms
steriod
-
Molecule consisting of 2 fatty acids, phosphate group bound to a glycerol molecule
phospholipid
-
A lipid composed of 3 fatty acids and a glycerol molecule
triglycerides
-
Soluble in water, head of the molecule
hydrophilic
-
Insoluble in water, forms tail of the molecule
hydrophobic
-
Nitrogen containing organic compound composed of bonded amino acid molecules
protein
-
Protein catalyzes specific biochemical reaction
enzymes
