Microsoft Strikes In The Most Unlikely of Places...

So, in case anyone was wondering, my research is on polyunsaturated fatty acids (PUFAs), specifically long-chain PUFAs, and they generally come in two varieties, omega-3 or omega-6. The omega means that the first double bond (or first locus of unsaturation) is the third (or sixth) position from the terminal carbon. Carbons are usually named from the head-group, beginning with the alpha carbon, followed by the beta and gamma carbons, etc, but when you're talking about 22 carbons, for example, that gets unwieldy.

Now, if you read the literature, you often see omega-3 or n-3 interchangeably. Now why n, do you ask? I've often wondered that. Classically, omega and n aren't really related. And if you look in the literature, the terminology only changed in the past five or ten years. Before 90s, they are never referred to as n-3 or n-6 fatty acids. What's up with that?

Well, I will tell you. Microsoft apparently doesn't use standard symbol encoding, so when transferring from Word to Adobe or a Postscript printer, omegas magically turn into ns and they are a pain to get back. And somehow, over the years, the fatty acid community has just come to accept the fact that n-3 = omega-3.

Damn you, Microsoft!!!
