Biological Function
This enzyme can be induced in many Candida yeast strains by growing them on long-chain alkanes as the major food source. Long-chain fatty alcohol oxidases participate in omega-oxidation of long chain alkanes or fatty acids. The alkane is first oxidized to an alcohol by an enzyme of the Cytochrome P450 family using NADPH. This alcohol is oxidized by long-chain fatty alcohol oxidase in yeast.
(This is different from the pathway found in mammalian tissues, which employs long-chain fatty alcohol dehydrogenase or fatty alcohol:NAD+ oxidoreductase and requires NAD+. Yeast have low levels of fatty alcohol dehydrogenase.)
The long-chain alcohol is then oxidized by long-chain fatty aldehyde dehydrogenase to a carboxylic acid, also producing NADH from NAD+. Fatty acids can be oxidized again to make dicarboxylic species that join with coenzyme A and enter the beta oxidation pathway in the peroxisome.
Long-chain alcohol oxidase is also used in germinating seedlings of jojoba (Simmondsia chinensis) to degrade esterified long-chain fatty alcohols stored as wax.

Famous quotes containing the words biological and/or function:
“Much of the ill-tempered railing against women that has characterized the popular writing of the last two years is a half-hearted attempt to find a way back to a more balanced relationship between our biological selves and the world we have built. So women are scolded both for being mothers and for not being mothers, for wanting to eat their cake and have it too, and for not wanting to eat their cake and have it too.”
—Margaret Mead (1901–1978)
“Uses are always much broader than functions, and usually far less contentious. The word function carries overtones of purpose and propriety, of concern with why something was developed rather than with how it has actually been found useful. The function of automobiles is to transport people and objects, but they are used for a variety of other purposes—as homes, offices, bedrooms, henhouses, jetties, breakwaters, even offensive weapons.”
—Frank Smith (b. 1928)
