Fats and Lipids: What Is the Difference? Essay - 1598.

Contrary to carbohydrates which constitute a family of relatively homogenous compounds, lipids form a very heterogenous class of compounds of widely differing structures and grouped according to their insolubility in water and solubility in organic solvents (ether, acetone, chloroform-alcohol mixtures, etc.).

Lipids A lipid is a group of naturally occurring molecules. That group includes fats, waxes, steroids, fat-soluble vitamins (A, D, E, and K) phospholipids, etc. They are broadly defined as hydrophobic or amphiphilic small molecules.

A lipid is defined as a water-insoluble biomolecule which has a high solubility in nonpolar organic solvents such as chloroform. The simplest lipids are the fats, which are triesters made up of one glycerol and three fatty acids.The term fats is also used as a general synonym for lipids, so the more precise terms triacylglycerols or triglycerides are preferable for the simplest lipids.Lipid - Lipid - Classification and formation: There are four major classes of circulating lipoproteins, each with its own characteristic protein and lipid composition. They are chylomicrons, very low-density lipoproteins (VLDL), low-density lipoproteins (LDL), and high-density lipoproteins (HDL). Within all these classes of complexes, the various molecular components are not chemically linked.Lipids are hydrocarbon compounds present as structural components of cell membranes. They are hydrophobic in nature therefore act as barrier for polar molecules. Lipids are present as highly reduced form of carbons, which upon oxidation yield large amount of energy.


Lipids, as a class of compounds, are insoluble in water but are soluble in other organic solvents. Examples of such solvents include acetone and ether. Waxes, steroids, phospholipids,and fatsare the most common types of lipid groups. Fats have glycerolin addition to three fatty acids.Lipid classification and nomenclature The term “lipid” has been loosely defined as any of a group of organic compounds that are insoluble in water but soluble in organic solvents. These chemical features are present in a broad range of molecules such as fatty acids, phospholipids, sterols, sphingolipids, terpenes and others.

What are blood lipids? Lipids are fat-like substances found in your blood and body tissues. Your body needs small amounts of lipids to work normally. How are my blood lipids measured? A blood test called a complete lipid profile is done. It is recommended that this test be done after an overnight fast. What happens if my lipids are too high? An excess amount of blood lipids.

Lipids are polymers and the long chains of repeating units are joined together in a condensation reaction where water is also produced. The most common types of lipids are triglycerides, phospholipids and waxes. Triglycerides are formed by three fatty acids and glycerol linked together by an ester bond.

Carbohydrates are one of the four major classes of biomolecules along with proteins, nucleic acids, and lipids. Carbohydrates are compounds that contain at least three carbon atoms, a number of hydroxyl groups, and usually an aldehyde or ketone group. They may contain phosphate, amino, or sulfate groups.

Lipids in general are molecules with a large non-polar extension, making them soluble in non-polar solvents, such as benzene, ether and chloroform. There exist some amphipathic lipids, which are lipids with both a hydrophilic portion, which gives them the property of water-solubility, as well as a hydrophobic portion, which is non-polar.

Classification of Carbohydrates. The main classification of carbohydrate is done on the basis of hydrolysis. This classification is as follow: Monosaccharides: These are the simplest form of carbohydrate that cannot be hydrolyzed any further. They have the general formula of (CH 2 O) n. Some common examples are glucose, Ribose etc.

In an effort to support the growing field of lipidomics and establish the importance of lipids as a major class of biomolecules, the International Lipid Classification and Nomenclature Committee (ILCNC) developed a “Comprehensive Classification System for Lipids” that was published in 2005 ().For the purpose of classification, we define lipids as hydrophobic or amphipathic small molecules.
