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) 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.

The prostaglandins (PG) are a group of physiologically active lipid compounds called eicosanoids "Eicosanoid Synthesis and Metabolism: Prostaglandins, Thromboxanes, Leukotrienes, Lipoxins". themedicalbiochemistrypage.org.

They are derived enzymatically from the fatty acid arachidonic acid.Ricciotti E, FitzGerald GA (May 2011). "Prostaglandins

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. It is the neurotoxin responsible for the motor neuron degeneration syndrome lathyrism.

The sweet pea, Lathyrus odoratus, is a flowering plant in the genus Lathyrus in the family Fabaceae (legumes), native to Sicily, southern Italy and the Aegean Islands.  Euro+Med Plantbase It is an annual climbing plant, growing to a height of 1–2 metres (3 ft 3 in – 6 ft 7 in), where suitable support is available. The leaves are pinnate with two leaflets and a

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.

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

In a chain-like biological molecule, such as a protein or nucleic acid, a structural motif is a common three-dimensional structure that appears in a variety of different, evolutionarily unrelated molecules.
