Guanosine triphosphate
Guanosine-5-triphosphate (GTP) is a purine nucleoside triphosphate. It is one of the building blocks needed for the synthesis of RNA during the transcription process. Its structure is similar to that of the guanosine nucleoside, the only difference being that nucleotides like GTP have phosphates on their ribose sugar. GTP has the guanine nucleobase attached to the 1 carbon of the ribose and it has the triphosphate moiety attached to riboses 5 carbon. GTP is essential to signal transduction, in particular with G-proteins, in second-messenger mechanisms where it is converted to guanosine diphosphate (GDP) through the action of GTPases. Guanosine triphosphate, also known as 5-GTP or H4GTP, belongs to the class of organic compounds known as purine ribonucleoside triphosphates. These are purine ribonucleotides with a triphosphate group linked to the ribose moiety. Thus, a GTP-bound tubulin serves as a cap at the tip of microtubule to protect from depolymerization; and, once the GTP is hydrolyzed, the microtubule begins to depolymerize and shrink rapidly. Guanosine triphosphate exists in all living species, ranging from bacteria to humans. In humans, guanosine triphosphate is involved in intracellular signalling through adenosine receptor A2B and adenosine. Guanosine-5-triphosphate (GTP) is a purine nucleoside triphosphate. Outside of the human body, guanosine triphosphate has been detected, but not quantified in several different foods, such as mandarin orange (clementine, tangerine), coconuts, new zealand spinachs, sweet marjorams, and pepper (capsicum). Cyclic guanosine triphosphate (cGTP) helps cyclic adenosine monophosphate (cAMP) activate cyclic nucleotide-gated ion channels in the olfactory system. It also has the role of a source of energy or an activator of substrates in metabolic reactions, like that of ATP, but more specific. It is used as a source of energy for protein synthesis and gluconeogenesis. For instance, a GTP molecule is generated by one of the enzymes in the citric acid cycle. GTP is also used as an energy source for the translocation of the ribosome towards the 3 end of the mRNA. During microtubule polymerization, each heterodimer formed by an alpha and a beta tubulin molecule carries two GTP molecules, and the GTP is hydrolyzed to GDP when the tubulin dimers are added to the plus end of the growing microtubule. The importing of these proteins plays an important role in several pathways regulated within the mitochondria organelle, such as converting oxaloacetate to phosphoenolpyruvate (PEP) in gluconeogenesis. GTP is involved in energy transfer within the cell. Guanosine triphosphate (GTP) is a guanine nucleotide containing three phosphate groups esterified to the sugar moiety. GTP functions as a carrier of phosphates and pyrophosphates involved in channeling chemical energy into specific biosynthetic pathways. GTP activates the signal transducing G proteins which are involved in various cellular processes including proliferation, differentiation, and activation of several intracellular kinase cascades. Proliferation and apoptosis are regulated in part by the hydrolysis of GTP by small GTPases Ras and Rho. Another type of small GTPase, Rab, plays a role in the docking and fusion of vesicles and may also be involved in vesicle formation. In addition to its role in signal transduction, GTP also serves as an energy-rich precursor of mononucleotide units in the enzymatic biosynthesis of DNA and RNA. [HMDB]. Guanosine triphosphate is found in many foods, some of which are oat, star fruit, lingonberry, and linden.

2-Amino-3-phosphonopropionic acid
2-Amino-3-phosphonopropionic acid (AP-3 or 2-AP3), also known as 3-phosphonoalanine, is a non-proteinogenc alpha-amino acid that is alanine in which one of the hydrogens of the terminal methyl group has been replaced by a dihydroxy(oxido)-lambda(5)-phosphanyl group. It is found in many organisms ranging from microbes to invertebrates to animals. In humans AP-3 is found in diverse tissues, such as liver, intestine and spleen. (PMID: 2627760). 2-Amino-3-phosphonopropionic acid is a ubiquitous naturally occurring phosphonate used as a source of phosphorus by many prokaryotic organisms (PMID: 30119975). The natural occurrence of 2-amino-3-phosphonopropionic acid. the phosphonate analogue of aspartic acid, was first reported by Kittredge & Hughes (PMID: 14214094) in the sea anemone Zoanthus sociatus and the protozoon Tetrahymena pyriformis. It has since been established to be one of the most widely distributed of the biogenic C–P compounds, particularly among the lower marine invertebrates (PMID: 19191873). AP-3 has been determined to be a metabotropic glutamate receptor agonist (PMID: 8836635). It has been shown to block the amyloid precursor protein (APP) release evoked by glutamate receptor stimulation in neurons of the cortex and hippocampus. APP accumulation is believed to produce the damage in Alzheimer’s disease (PMID: 7644542). 2-Amino-3-phosphonopropionic acid (AP-3)is a normal human metabolite found in diverse tissues, such as liver, intestine and spleen. (PMID 2627760) AP-3 is a metabotropic glutamate receptor agonist (PMID 8836635) shown to block the amyloid precursor protein (APP) release evoked by glutamate receptor stimulation in neurons of the cortex and hippocampus; APP accumulation is believed to produce the damage in Alzheimer disease (PMID 7644542) [HMDB] D018377 - Neurotransmitter Agents > D018683 - Excitatory Amino Acid Agents > D018691 - Excitatory Amino Acid Antagonists KEIO_ID A131 DL-AP3 is a competitive mGluR1 and mGluR5 antagonist.
