Octacosane is an alkane hydrocarbon with the structural formula CH3(CH2)26CH3. CAS registry numbers are unique numerical identifiers for chemical compounds, polymers, biological sequences and alloys. ... The molecular mass of a substance (less accurately called molecular weight and abbreviated as MW) is the mass of one molecule of that substance, relative to the unified atomic mass unit u (equal to 1/12 the mass of one atom of carbon-12). ... An alkane in organic chemistry is a saturated hydrocarbon without cycles, that is, an acyclic hydrocarbon in which the molecule has the maximum possible number of hydrogen atoms and so has no double bonds. ... In chemistry, a hydrocarbon is any chemical compound that consists only of carbon (C) and hydrogen (H). ... Many chemical compounds, especially hydrocarbons, can exist in different geometric configurations. ...

JIS: Tschinkel 2.12.2002 (4275 words)
The carrier gas was helium, and the initial column temperature was between 150 and 200 °C and was programmed to increase to 320°C at 3 or 4°/min and held at 320°C. The system was operated and data collected with a Hewlett-Packard 5970C computer.
The system was calibrated, and the quality of the chromatogram monitored, with a standard mixture consisting of: methyl heptadecanoate, methyl icosanoate, 3-methyltricosane, tricosanyl acetate, octacosane, tetracontane, and tricosanyl heptadecanoate, run at six concentrations.
The mass spectral data for the wax esters were analyzed by single-ion extraction of the data (Nelson et al., 2000).
Bee Pollen : by Ray Sahelian, M.D., Benefits of Bee Pollen (753 words)
The effects of extraction pressure, extraction temperature and the grinding size of the bee pollen on the yields were discussed.
The main composition of the fatty oil from the bee pollen was: oleic acid, palmitic acid, linoic acid, pentacosane, octacosane and so on.
Many competitive sportsmen in this country regularly use pollen extract as a dietary supplement in the belief that it can lead to an improvement in performance.
