Lipids are a class of hydrocarbon-containing organic compounds essential for the structure and function of living cells. Lipids are characterized by being water-insoluble and soluble in nonpolar organic solvents. Although the term lipid is often used as a synonym for fat, the latter is in fact a subgroup of lipids called triglycerides.
Along with proteins, nucleic acids and carbohydrates, lipids are one of the major classes of biologically important molecules or biomolecules. However, unlike these other groups of molecules, lipids comprise a broader and more diverse range of structures. The term lipid really is a catch-all phrase for a wide variety of hydrocarbon-based molecules of biological origin that are predominantly nonpolar or hydrophobic ("water-fearing"), meaning that they do not interact well with polar solvents like water, and are instead soluble in less polar organic solvents. Most lipids also have some polar or hydrophilic ("water-loving") character. This makes them amphipathic or amphiphilic molecules (having both hydrophobic and hydrophilic portions). In the case of cholesterol, the polar group is a mere -OH (hydroxyl or alcohol). In the case of phospholipids, the polar groups are considerably larger and more polar. Lipids encompass a huge range of structures. They can be aliphatic or aromatic. They can be acyclic or cyclic, straight or branched, saturated or unsaturated. Lipids can be flexible or rigid. This diversity makes it impossible to define lipids on the basis of a single core structural feature or biosynthetic origin, as can be done with the other major groups of biomolecules.
Lipids play diverse and important roles in nutrition and health. Many lipids are absolutely essential for life. However, there is also considerable awareness that abnormal levels of certain lipids, particularly cholesterol (in hypercholesterolemia) and, more recently, trans fatty acids, are risk factors for heart disease and other diseases.
hey, hope this helps. I'll let you do the organising and double spacing, and you can edit it as you want. take care x

1. Look up this word: "plagiarism."
2. Then look up the academic consequences of committing plagiarism.
3. Then forget about getting admitted to a good college or grad school or law school, and forget about getting a good job. Plagiarism on your record is a deal-killer.
4. Now, go do your own research. Use Yahoo or Google to find helpful material, and then put it in your own words.

WHATEVER!!!!
you know, I think it is awesome that YA has this homework helps section, but you missed something.
It is homework HELP, not homework DO.
Now, google those silly lipids and get busy!
PS go with the 10 bucks. That topic sounds so boring, I would charge you WAY more than that!!! LOL

The lipids are a large and diverse group of naturally occurring organic compounds that are related by their solubility in non polar organic solvents (e.g. ether, chloroform, acetone & benzene) and general insolubility in water. There is great structural variety among the lipids.
These sites should give you enough information to do your essay. Good luck with it.

No do your own work if I did it for you it my work not yours. That is called cheating. Ok double spaced well open Microsoft Word and start typing it yourself lazy.

you are Irresponsible!!!! Don't cheat !!!! If you have to stay up all night do so , but don't cheat... Tell your parents to send a note to your teacher for an extention, and I mean if it is that important I guess you can talk to your parents and miss a day of school and say you are sick if you really think its worth it. But don't cheat

lipid is soluble in achohol,but not soluble in water.like carbohydrates,it is made up of carbon,hydrogen and oxygen.that is all i know.
