AMP
Adenosine monophosphate
ADP
Adenosine diphosphate
ATP
Adenosine triphosphate
Cyclic AMP
Modified version of AMP used for intracellular signaling.
Fatty acid
A carboxyl group with a long hydrocarbon tail.
Unsaturated fatty acids
Contains double bonds in its hydrocarbon tail. Liquid at room temp.(ie. Oleic acid)
Saturated fatty acids
Has no double bonds in its hydrocarbon tail. Solid at room temp. (ie. Stearic acid)
Triacylglycerols
Storage version of fatty acids. 3 fatty acids linked to a glycerol via ester bonds. (ie. Fat droplets)
Steroids
Cholesterol - in lipid membranes. Testosterone - male hormone.
Glycolipids
Similar to phospholipids but contains one or more sugar residues on its head, rather than a phosphate gruop.
