	GUANOSINE
		Guanosine Triphosphate (GTP) : a nucleotide composed of guanine, the sugar ribose, and three phosphate groups; the source of the guanosine found in RNA and also involved in many cellular processes, including microtubule assembly, protein synthesis, and cell signaling, due to the energy it releases upon removal of its terminal phosphate group (yielding GDP).
		Guanosine diphosphate (GDP) : a nucleotide composed of pyrophosphate of guanosine which serves as a carrier for mannose residues in glycoprotein synthesis and as a substrate for a phosphorylation reaction of the tricarboxylic acid cycle.
		Guanosine monophosphate (GMP, aso known as guanylic acid) : a nucleotide composed of pyrophosphate of guanosine which is formed during the hydrolysis of nucleic acidis and is a regulator of pyrimidine nucleotide biosynthesis.

		ddNTP.GIF a nucleoside triphosphate analog that causes termination of an elongating DNA molecule when incorporated by DNA polymerase because of the absence of a 3´-hydroxyl residue on the sugar portion of the compound, which is necessary for the formation of the 3' to 5' phosphate linkage in an elongating DNA chain.
		The sugar molecules are modified by the presence of a purine or pyrimidine nucleoside or "base" attached to the first, or 1', carbon and the oxygen-phosphorus-oxygen bond links the third, or 3', carbon to the fifth, or 5', carbon of the adjacent sugar molecule.
		thymidine triphosphate, a deoxyribose molecule with the pyrimidine thymine attached to the 1´ carbon and a chain of three oxygenated phosphorus atoms attached to the 5' carbon.

	Guanosine triphosphate - Wikipedia, the free encyclopedia
		Guanosine triphosphate (GTP) is also known as guanosine-5'-triphosphate and G3P.
		GTP is a purine nucleotide that is incorporated into the growing RNA chain during RNA synthesis, and used as a source of energy for protein synthesis.
		GTP is also essential to signal transduction, where it is converted to GDP (guanosine diphosphate) through the action of GTPases.

	AllRefer.com - guanine (Biochemistry) - Encyclopedia (Site not responding. Last check: )
		When combined with the sugar ribose in a glycosidic linkage, guanine forms a derivative called guanosine (a nucleoside), which in turn can be phosphorylated with from one to three phosphoric acid groups, yielding the three nucleotides GMP (guanosine monophosphate), GDP (guanosine diphosphate), and GTP (guanosine triphosphate).
		GTP acts as a coenzyme in carbohydrate metabolism and in the biosynthesis of proteins; it can readily donate one of its phosphate groups to adenosine diphosphate (ADP) to form adenosine triphosphate (ATP), an extremely important intermediate in the transfer of chemical energy in living systems.
		GTP is the source of the guanosine found in RNA and deoxyguanosine triphosphate (dGTP) is the source of the deoxyguanosine in DNA, and thus guanine is intimately involved in the preservation and transfer of genetic information.
