'Medium-chain fatty acid' and 'Long-chain fatty acid' both currently redirect to 'Fatty acid', so there are two circular links in the section on 'Length of free fatty acid chains'. I'm going to remove these two links.

"Free fatty acids are an important source of fuel for many tissues since they can yield relatively large quantities of ATP. Many cell types can use either glucose or fatty acids for this purpose. However, heart and skeletal muscle prefer fatty acids. On the other hand, the brain cannot use fatty acids as a source of fuel, relying instead on glucose, or on ketone bodies produced by the liver from fatty acid metabolism during starvation, or periods of low carbohydrate intake."
I doubt it. This should be fact-checked. Lantoka 11:43, 6 April 2006 (UTC)
The statements that "a chain has many cis bonds, it becomes quite curved" and that "Alpha-linolenic acid, with three double bonds, forms a hooked shape." seem misleading. As long as fatty acids have at least one C-C single bonds along their chain, they can assume an infinite number of conformations, only a subset of which are consistent with these statements. For example the structure of Alpha-linolenic acid drawn in its article is not hooked but straight. It all depends on the free rotation around the C-C single bonds.
It seems more correct to mention that cis bonds, by introducing kinks in the chain, decrease the conformational freedom of fatty acids. The effect of this is that in restricted environments, such as when fatty acids are part of a phospholipid in a lipid bilayer, or triglicerides in lipid droplets, cis bonds limit the ability of fatty acids to be closely packed and therefore could affect the melting temperature of the membrane or of the fat. -- InfoCan 16:12, 26 May 2006 (UTC)
Should acetic and butyric acids be listed as saturated fatty acids when the intro says that fatty acids are generally understood to have 8 carbons or more? -- InfoCan 16:18, 26 May 2006 (UTC)
Wouldn't it make more sense to write: "A cis configuration means that the two hydrogens are on the same side of the double bond" and "A trans configuration, by contrast, means that the next two hydrogen atoms are bound to opposite sides of the double bond"?
"Changes in the levels and balance of these fatty acids due to a typical Western diet rich in omega-6 and poor in omega-9 fatty acids is alleged to be associated with depression and behavioral change, including violence."
Shouldn't this be:

Hi - excuse my ignorance about fatty acids, but I'm trying to resolve/understand all the links to Chain and I see there's a reference in the first sentence of this article but I'm not sure what it means. If if refers to chain as a sequence of molecules, it should be a link to Chain (sequence) -- Mortice 23:11, 31 October 2006 (UTC)
I have been investigating coconut oil and in the process found that while most articles and discussions mention saturation they do not discuss length and I do not have sufficient knowledge to judge the validity or siginificance of this ommission. There seems to be some rising debate about the relative value of long- versus medium-chain fatty acids. Here is the article that put length on my radar: http://www.westonaprice.org/knowyourfats/skinny.html#fatty
If the length of fatty acids is a significant factor then this article should include some mention of it and even if it is not significant it might be helpful to know why not. Donberg68 23:13, 23 February 2007 (UTC)
Who cares about vitamin E in oils anyway? From this table, I see that the more polyunsaturated oils generally have more vitamin E. They need more refining and thus aren't that rich in vitamin E after all. Also, they require more antioxidants (like Vitamin E) for your body to use them. Liquid vegetable oils are always refined and deprived of their nutrients once they reach the supermarket (besides olive oil) and if they're highly polyunsaturated (which all liquid vegetable oils are besides olive oil, nut oil, avocado oil, tea seed oil and maybe some others), they'll have significant amounts of trans fats. Also, of the oils, the one with the most vitamin E is palm oil (wheat germ oil isn't commonly in the supermarket, just used as a supplement). I also bet unrefined/virgin/extra virgin olive oil would be high on the common oil list. When unrefined oils are used as supplements, that's a whole different story (unrefined wheat germ oil is packed with Vitamin E).

There's a little inconsistency on Wikipedia about whether certain short-chain compounds are considered fatty acids. This mainspace omits anything shorter than butyric acid from the table of saturated fatty acids, but language in a later section vaguely implies that formic and acetic acids are fatty acids. The Short chain fatty acid article includes acetic and propionic acids, but not formic. Meanwhile, the Acetic acid article implies that acetic acid is a fatty acid, the Propionic acid article states that propionic acid is not a fatty acid, and the Formic acid article is silent on the subject.

Omega numbering showed in the figure is wrong. The farest carbon atom (from the carboxyl group) should be numbered as ω (as used in ω-hydroxy acids), the second to last carbon should be numbered as ω−1, the third to last atom should be numbered as ω−2, and so on. When the position of a double bond is specified, the lowest locant (corresponding to two involved carbons) must be stated. Thus, a ω−3 fatty acid presents a C=C bond linking carbons ω−3 and ω−2. Differences between carbon atoms ω and ω−1 can be easily inferred from the literature: -Å. Ellin, S. V. Jakobsson, J. B. Schenkman, S.
