lipid question.

Members don't see this ad.

i was studying lipid, one of the 4 major classes of organic compounds.
one of the definitions says it has 3 fatty acids and 1 glycerol.

one of the lipids are called phospholipids and it has 2 fatty acids and 1 glycerol.

if lipid is supposed to have 3 fatty acids, then how can we call phospholipids a lipid when it has only 2 fatty acids?

I believe the 3 fatty acids and 1 glycerol is triacylglyceride, which is a type of lipid.

The phospholipid is a special type of lipid, in which there are two fatty acid, one glycerol and one phosphorylated group.

There are also many other types of other lipids: spingolipids, glycolipids, waxes, fatty acids, steroids........etc. So lipid refers to a diverse range of molecules.

Yes. Lipid is the one of the major organic compound (Macromolecules), it consist of 3 fatty acid molecule bonded with 1 glycerol backbon. However, there are 6 major groups of lipids: Fatty acids, triacyglycerol, phospholipids, glycolipids, steroids, and terpenes. For example, fatty acids are the building blocks for most of the lipids, but not all complex lipids.

Hope this is clear.

so...is it true that lipid has 3 fatty acid and 1 glycerol?

then when it says 2 fatty acid and 1 glycerol it's also a lipid but just part of a complete form of lipid, is it right way of remembering it?

and is it necessary to remember all those 6 types of lipid?

Well, I think it is always better if you can understand the concept rather then memorize the whole thing. Just do the best you can. 🙂
