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.
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.Read More
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.Read More
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.Read More
Carbohydrates: definition, classification and functions. Carbohydrates, together with lipids, proteins and nucleic acids, are one of the four major classes of biologically essential organic molecules found in all living organisms. Carbohydrates, all coming from the process of photosynthesis.Read More
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.Read More
Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. Examples of lipids include fats, oils, waxes, certain vitamins (such.Read More
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.Read More
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.Read More

Fatty acids are composed of a hydrophilic carboxylic acid group attached to a fatty hydrophobic chain of carbon atoms, referred to as the fatty tail. The fatty acids are classified as either saturated or unsaturated depending on the structure. Saturated fatty acids contain only single.Read More
