Lipids Research Paper:
Lipids topic gives you a very good chance for writing a successful research paper in university or college.
Lipids in the chemistry are a collective name for a large group of substances consisting of fats and fat-like substances. The very definition of a lipid is unclear and vague but it typically includes topics from living organisms that are soluble in nonpolar solvents and insoluble in water. It is thus mainly the physical properties and biological existence that determines whether the substance is a lipid or not.
Fatty acids are carboxylic acids consisting of carbon, hydrogen, and oxygen, and only contains a carboxyl group bound to an alkyl group. The saturated fatty acids have the general formula CH3(CH2)nCOOH where n is generally a number between 2 and 18.

By fatty acids, the long and unbranched alkyl group is meant to be understood. However, the alkyl group can be unsaturated, it means that there are double bonds between two or more carbon atoms, which means that the fatty acid is not saturated with hydrogen ions. The double bond leading to folding of the molecular structure.
Often, fat and lipids as synonyms but fat is a subgroup of lipids more strictly known as triglycerides.
Triglycerides consist of glycerol esterified with three fatty acids. Triglycerides in the liquid form are usually called oils. The chemical characteristics of triglycerides are determined by the constituent fatty acids. Triglycerides are burned by the body’s cells for energy released by beta-oxidation.
Waxes in chemistry are an ester of a higher fatty acid and a higher alcohol, known as fatty alcohol.
They can be mixtures of several different fats and mineral oils. They have the general formula CH3(CH2)nCOOC(CH2)mCH3.
All living organisms are composed of cells that make up its smallest functional units. The cell boundary to the outside world consists of cell membrane that allows the organisms to concentrate different topics and use different gradients to drive various processes. The membrane typically consists of phospholipids, cholesterol, and various proteins. The chemical properties of the different ingredients are essential for cell function.
Phospholipids are the main component of all cell membranes and are the backbone of the cell membranes. They have a hydrophobic (water repellent) and a hydrophilic (water attracting) end which gives the molecule amphiphilic properties.
Otherwise, the non-polar substance and has only weak bindings between molecules. This prevents the charged and polar molecules to pass through cell membrane. Neutral substances, such as oxygen and carbon dioxide can pass without difficulty.
Phospholipids are phosphate esters of glycerol. The esters with two fatty acid molecules and a molecule of phosphoric acid. The phosphoric acid also formed with further ester, an alcohol group which usually also contains an amino group.
Actually sample research papers on lipids is a decent choice for a good research proposal.
