The following article contains the false notion that cholesterol increase the fluidity of the cell membrane. I always thought that it decreased fluidity both by being an odd shape and by getting the way of the phospholipids. In another article, this is discussed. One of these articles must have been written by a very ignorant person.

What cholesterol does to membrane fluidity depends on the exact circumstances. Under the conditions we find normal, cholesterol decreases membrane fluidity by filling space between phospholipids. However, under freezing conditions (say, for example, that you are a fish in near-freezing water), cholesterol increases membrane fluidity by inhibiting crystalization of the membrane. — Preceding unsigned comment added by Apguy2000 (talk • contribs) 13:41, 14 March 2011 (UTC)[reply]

"The molecule is 'quite flat'". How flat precisely? Is it even a relevant fact to its properties or reaction pathways? —Preceding unsigned comment added by 86.152.207.246 (talk) 19:07, 1 February 2009 (UTC)[reply]

Is Fusidic acid a sterol

Is Fusidic acid a sterol? Its structure seems to satisfy the description. - Rod57 (talk) 11:13, 13 March 2013 (UTC)[reply]

Both plant sterols and plant stanols cause Colon Cancer in mice.

https://helda.helsinki.fi/handle/10138/45404 Both plant sterols and plant stanols increased the number of adenomas in the small intestine of ApcMin mice. Plant stanol feeding increased the number of intestinal tumors in both genders, whereas plant sterol feeding increased the number of tumors more pronouncedly in female mice. ee1518 (talk) 19:56, 16 February 2015 (UTC)[reply]

I have only basic knowledge of biology & wikis and this is my first comment :) Wondering why DHEA/DHEAS are not mentioned as examples of sterol. Even their respective wiki pages list them by the more generic term of steroids.
