the question is from ap and i am lost. i have read and read but none of the answers seem right. then agian i have been looking at the book all day. lol
cholesterol is an example of a
a. review organic compounds
c. fatty acid
help!!!! lol tia!!
i'm pretty sure it is not a prostaglandin. a prostaglandin is a fatty acid.
it is an organic compound, but i'm not sure what is meant by answer "a".
it is a lipid - subgroup steriod.
the "lipids" include:
fats - made of 3 fatty acids & glycerol
phospholipids - 2 fatty acids & glycerol
steriods - lipids with a 4 ring structure
but it doesn't mention the glycerol with the steriods, only that cholestrol is insoluble in water & is found in the cell membranes of animal cells.
so after looking in my a&p & micro book i'm now confused as well. i don't have a chemistry book, but that would be my next place to look.
