Neuromedin C 1-8
Neuromedin C is a neuropeptide derived from the same precursor polypeptide as neurotensin, and with similar but subtly distinct expression and effect. Neurotensin is a 13 amino acid neuropeptide that is implicated in the regulation of luteinizing hormone and prolactin release and has significant interaction with the dopaminergic system. Neurotensin was first isolated from extracts of bovine hypothalamus based on its ability to cause a visible vasodilation in the exposed cutaneous regions of anesthetized rats. This structure shows the 1-8 fragment of neuromedin c. Neuromedin C is a neuropeptide derived from the same precursor polypeptide as neurotensin, and with similar but subtly distinct expression and effect
Gliadorphin
C43H57N9O11 (875.4177331999999)
Gliadorphin (or gluteomorphin) is a 7-residue opioid peptide (Tyr-Pro-Gln-Pro-Gln-Pro-Phe) derived from the wheat protein gluten. Other related grains such as rye, barley and oats also contain the same sequence of amino acids found in gluten. Gliadorphin is very similar to casomorphin (a casein-derived peptide). Gliadorphin has been verified by mass spectrometry techniques to be present in urine samples of children with autism.
PS(20:5(5Z,8Z,11Z,14Z,17Z)/20:5(7Z,9Z,11E,13E,17Z)-3OH(5,6,15))
PS(20:5(5Z,8Z,11Z,14Z,17Z)/20:5(7Z,9Z,11E,13E,17Z)-3OH(5,6,15)) is an oxidized phosphatidylserine (PS). Oxidized phosphatidylserines are glycerophospholipids in which a phosphorylserine moiety occupies a glycerol substitution site and at least one of the fatty acyl chains has undergone oxidation. As all oxidized lipids, oxidized phosphatidylserines belong to a group of biomolecules that have a role as signaling molecules. The biosynthesis of oxidized lipids is mediated by several enzymatic families, including cyclooxygenases (COX), lipoxygenases (LOX) and cytochrome P450s (CYP). Non-enzymatically oxidized lipids are produced by uncontrolled oxidation through free radicals and are considered harmful to human health (PMID: 33329396). As is the case with diacylglycerols, phosphatidylserines can have many different combinations of fatty acids of varying lengths, saturation and degrees of oxidation attached at the C-1 and C-2 positions. PS(20:5(5Z,8Z,11Z,14Z,17Z)/20:5(7Z,9Z,11E,13E,17Z)-3OH(5,6,15)), in particular, consists of one chain of one 5Z,8Z,11Z,14Z,17Z-eicosapentaenoyl at the C-1 position and one chain of Lipoxin A5 at the C-2 position. Phospholipids are ubiquitous in nature and are key components of the lipid bilayer of cells, as well as being involved in metabolism and signaling. Similarly to what occurs with phospholipids, the fatty acid distribution at the C-1 and C-2 positions of glycerol within oxidized phospholipids is continually in flux, owing to phospholipid degradation and the continuous phospholipid remodeling that occurs while these molecules are in membranes. Oxidized PSs can be synthesized via three different routes. In one route, the oxidized PS is synthetized de novo following the same mechanisms as for PSs but incorporating oxidized acyl chains (PMID: 33329396). An alternative is the transacylation of one of the non-oxidized acyl chains with an oxidized acylCoA (PMID: 33329396). The third pathway results from the oxidation of the acyl chain while still attached to the PS backbone, mainly through the action of LOX (PMID: 33329396).
