An amphipathic molecule is one that has regions of different polarities, and can have both polar and non-polar areas within the same molecule. An example is a fatty acid. It has a non-polar hydrocarbon chain and a polar head <ref>(2012)Molecules that are both polar and non-polar, [Online], Available: http://besocratic.colorado.edu/CLUE-Chemistry/chapters/chapter6txt-5.html [22 October 2014]</ref>

An antagonist is a molecule that inhibits their target so that it can no longer be activated by an [[Agonist|agonist]]. A competitive antagonist is one that blocks the same [[binding site|binding site ]]as the agonist on the [[target molecule|target molecule]]<ref>Golan, D., Tashjian, A. and Armstrong, E.

UTP stands for uridine Triphosphate. It is a nucleotide that is involved in RNA synthesis<ref name="uridine triphosphate">http://medical-dictionary.thefreedictionary.com/uridine+triphosphate</ref>. UTP has a molecular weight of 84.141086 g/mol and a molecular formula C9H15N2O15P3<ref name="Uridine Triphosphate - Compound Summary">http://pubchem.ncbi.nlm.nih.gov/summary/summary.cgi?cid=6133</ref>.

The formation of UTP - uridine monophosphate reacts with ATP to for uridine diphosphate. The uridine diphosphate is converted to uridine triphosphate<ref>Gropper. S and Smith. J, Advanced Nutrition and Human Metabolism, 6th edition, 2012: 221</ref>.
