Human placental lactogen (hPL)
Human placental lactogen (hPL), also called human chorionic somatomammotropin (HCS), is a polypeptideplacental hormone, the human form of placental lactogen (chorionic somatomammotropin). Its structure and function are similar to those of human growth hormone. It modifies the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus.
Human chorionic gonadotropin (hCG)
Human chorionic gonadotropin (hCG) is a hormone for the maternal recognition of pregnancy produced by trophoblast cells that are surrounding a growing embryo (syncytiotrophoblast initially), which eventually forms the placenta after implantation.Cole LA (2009). "New discoveries on the biology and detection of human chorionic gonadotropin". Reprod. Biol. Endocrinol. 7: 8. doi:10.1186/1477-7827-7-8. PMC 2649930. PMID 19171054.Gregory JJ,
Prostaglandins (PG)
The prostaglandins (PG) are a group of physiologically active lipid compounds called eicosanoids "Eicosanoid Synthesis and Metabolism: Prostaglandins, Thromboxanes, Leukotrienes, Lipoxins". themedicalbiochemistrypage.org. Retrieved 2018-09-21. having diverse hormone-like effects in animals. Prostaglandins have been found in almost every tissue in humans and other animals. They are derived enzymatically from the fatty acid arachidonic acid.Ricciotti E, FitzGerald GA (May 2011). "Prostaglandins

What Is A Siderophore?
Siderophores (Greek: "iron carrier") are small, high-affinity iron-chelating compounds that are secreted by microorganisms such as bacteria and fungi. They help the organism accumulate iron. Although a widening range of siderophore functions is now being appreciated. Siderophores are among the
Delftia acidovorans
Delftia acidovorans is a Gram-negative, motile, non-sporulating, rod-shaped bacterium known for its ability to biomineralize gold and bioremediation characteristics.
Cupriavidus metallidurans
C. metallidurans plays a vital role, together with Delftia acidovorans, in the formation of gold nuggets. It precipitates metallic gold from a solution of gold(III) chloride, a compound highly toxic to most other microorganisms.
The drug phencyclidine (PCP or ‘Angel Dust’) antagonizes glutamic acid non-competitively at the NMDA receptor
The drug phencyclidine (more commonly known as PCP or 'Angel Dust') antagonizes glutamic acid non-competitively at the NMDA receptor. For the same reasons, dextromethorphan and ketamine also have strong dissociative and hallucinogenic effects. Acute infusion of the drug LY354740 (also known as eglumegad, an agonist of the metabotropic glutamate receptors2 and 3) resulted in a marked diminution of yohimbine-induced stress response in bonnet macaques
Oxalyldiaminopropionic acid (ODAP) is a structural analogue of the neurotransmitter glutamate found in the grass pea Lathyrus sativus
Oxalyldiaminopropionic acid (ODAP) is a structural analogue of the neurotransmitter glutamate found in the grass pea Lathyrus sativus. It is the neurotoxin responsible for the motor neuron degeneration syndrome lathyrism. Woldeamanuel, Yohannes W.; Hassan, Anhar; Zenebe, Guta (2011-11-12).

Tryptophan tryptophylquinone (TTQ) formation
Tryptophan tryptophylquinone (TTQ) is an enzyme cofactor, generated by posttranslational modification of amino acids within the protein. Methylamine dehydrogenase (MADH), an amine dehydrogenase, requires TTQ for its catalytic function. Davidson, V. L.; Liu, A. (2012).

Kaede (protein)
Kaede is a photoactivatable fluorescent protein naturally originated from a stony coral, Trachyphyllia geoffroyi. Its name means "maple" in Japanese. With the irradiation of ultraviolet light (350–400 nm), Kaede undergoes irreversible photoconversion from green fluorescence to red fluorescence. Kaede is a homotetrameric protein with the size of 116 kDa. The tetrameric structure was deduced as its primary structure
