ubiquinone-8

2,3-dimethoxy-5-methyl-6-[(2E,6E,10E,14E,18E,22E,26E)-3,7,11,15,19,23,27,31-octamethyldotriaconta-2,6,10,14,18,22,26,30-octaen-1-yl]cyclohexa-2,5-diene-1,4-dione

C49H74O4 (726.5587)

Ubiquinone-8, also known as coenzyme q8 or coq8, is a member of the class of compounds known as ubiquinones. Ubiquinones are coenzyme Q derivatives containing a 5, 6-dimethoxy-3-methyl(1,4-benzoquinone) moiety to which an isoprenyl group is attached at ring position 2(or 6). Thus, ubiquinone-8 is considered to be a quinone lipid molecule. Ubiquinone-8 is practically insoluble (in water) and an extremely weak basic (essentially neutral) compound (based on its pKa). Ubiquinone-8 can be found in a number of food items such as kumquat, celery leaves, hazelnut, and jicama, which makes ubiquinone-8 a potential biomarker for the consumption of these food products. Ubiquinone-8 may be a unique E.coli metabolite.

SM(d17:1/18:2(10E,12Z)+=O(9)) is a type of oxidized sphingolipid found in animal cell membranes. It usually consists of phosphorylcholine and ceramide. SM(d17:1/18:2(10E,12Z)+=O(9)) consists of a sphingosine backbone and a 9-oxo-octadecadienoyl chain. In humans, sphingomyelin is the only membrane phospholipid not derived from glycerol. Like all sphingolipids, SM has a ceramide core (sphingosine bonded to a fatty acid via an amide linkage). In addition, it contains one polar head group, which is either phosphocholine or phosphoethanolamine. The plasma membrane of cells is highly enriched in sphingomyelin and is considered largely to be found in the exoplasmic leaflet of the cell membrane. However, there is some evidence that there may also be a sphingomyelin pool in the inner leaflet of the membrane. Moreover, neutral sphingomyelinase-2, an enzyme that breaks down sphingomyelin into ceramide, has been found to localize exclusively to the inner leaflet further suggesting that there may be sphingomyelin present there. Sphingomyelin can accumulate in a rare hereditary disease called Niemann-Pick Disease, types A and B. Niemann-Pick disease is a genetically-inherited disease caused by a deficiency in the enzyme sphingomyelinase, which causes the accumulation of sphingomyelin in spleen, liver, lungs, bone marrow, and the brain, causing irreversible neurological damage. SMs play a role in signal transduction. Sphingomyelins are synthesized by the transfer of phosphorylcholine from phosphatidylcholine to a ceramide in a reaction catalyzed by sphingomyelin synthase.
