When we discuss the terpenes we are most interested in the carbon skeleton.

Terpenes. When we discuss the terpenes we are most interested in the carbon skeleton. Terpenes contain carbon atoms in multiples of five They are made by joining together 5-carbon isoprene units Oxygen-containing terpenes are sometimes called terpenoids. Terpenes.

Terpenes

Terpenes. By John Amba & John Sebua. Terpenes. - are a class of molecules that typically contain either ten or fifteen carbon atoms built from a five carbon building block called isoprenes . Isoprene (C 5 H 8 ).

Ubiquinone Analysis Service

Ubiquinone is 2,3-dimethoxy-5-methyl-6-multiprenyl-1, 4-benzoquinone, also known as CoEnzyme Q (CoQ10, Q). The reduced form (QH2) is called ubiquinol and the partially reduced free-radical form is called semiquinone. The quinone group allows CoEnzyme Q to function as an electron-carrier, while the highly hydrophobic tail of isoprene units helps to confine CoEnzyme Q to lipid-rich areas of cells. In most species the number of isoprene units is between 6 and 10. CoEnzyme Q in mammals either has 9 (CoQ9) or 10 (CoQ10) isoprene units. In mouse and rat nearly 90% of ubiquinone is CoQ9, whereas rabbit, pig, goat, sheep, cow and horse have predominantly CoQ10, with 4% or less of CoQ9. CoQ10 is also predominant in guinea pigs and humans.
