[edit] Complete oxidation (title added)

What is the complete oxidation of stearic acid? —The preceding unsigned comment was added by 195.194.252.14 (talk • contribs) .

Carbon dioxide and water. If you're asking for the balanced equation, do your own homework. —Keenan Pepper 02:23, 8 August 2006 (UTC)
Amen to that comment, Keenan. Goldy496 (talk) 23:49, 2 February 2008 (UTC)

[edit] Where are the carbon atoms? (title added)

If CH3(CH2)16COOH is the formula, then where is the carbon in the picture? All I see are oxygen and hydrogen. Subversive 4 July 2005 04:04 (UTC)

The carbon is never shown in this kind of pictures. Xatufan
The points connecting the various line segments are understood to be carbon —The preceding unsigned comment was added by 129.24.141.230 (talk • contribs) .
In organic chemistry, it becomes a nuisance to draw out dozens of C's. Instead, they are represent by lines connecting them and they are assumed to have an appropriate number of Hydrogens attached to each vertex.71.168.113.85 00:31, 3 April 2007 (UTC)

[edit] Reaction with water (title added)

What is the equation for its reaction with water? —The preceding unsigned comment was added by 203.173.2.13 (talk • contribs) .

Do your own homework. —Keenan Pepper 02:23, 8 August 2006 (UTC)

[edit] Conversion in the human body (title added)

I've heard that the human body converts stearic acid to oleic acid for processing, which is why cocoa butter (high in stearic acid) isn't as unhealthy as other kinds of saturated fats. Is this true? Anyone know more about this? Frankg 18:34, 10 February 2006 (UTC)

That's interesting. I'll look it up. —Keenan Pepper 02:23, 8 August 2006 (UTC)
I added a section based on an isotope study I found. How's that? —Keenan Pepper 03:07, 8 August 2006 (UTC)
Definitely; thanks for digging that up! Frankg 20:36, 8 August 2006 (UTC)

[edit] Desaturation (title added)

How conduct the desaturation of stearic acid ? —The preceding unsigned comment was added by Grzybowski (talk • contribs) .

[edit] Gelatin?

Would it be accurate to say that calcium stearate and magnesium stearate serve some of the same purposes as gelatin? A package of breath mints had calcium stearate in its list of ingredients (but no gelatin), while other brands such as Altoids do list gelatin. -- Gyrofrog (talk) 02:04, 7 December 2006 (UTC)

[edit] Freezing point

Someone wrote:

FreezingPt=35.1 °C

in the infobox. This does not show up in the infobox, as it is not a standard item. Also, I find it a bit strange that it's so far from the melting point (69.6 °C). If this is correct, we need to put it in the article somehow, with a reference. --Slashme 07:55, 1 October 2007 (UTC)

[edit] Trans Fatty Acid/Stearic Acid clarification and link

It would be helpfull if this page stated that hydrogenated vegitable oils are commonly known as Trans Fatty Acids and make a link to the Trans Fatty Acids page. This page missleads one to beleive that the hydrogenation of vegitable oils creates the same stearic acid that occurs in nature, when naturally occuring Stearic Acid has studies that suggest it lowers heart disease and is good for human ingestion, while Trans Fatty Acids have studies that suggest the opposite. 206.166.230.226 (talk) 18:59, 7 February 2008 (UTC)
