PPT-Lipids Lipids Lipids

are a large and diverse group of naturally occurring organic compounds that share some general properties General Properties of Lipids Insoluble in water Soluble in nonpolar organic solvents . Chapter 29. 2. Lipids. are . biomolecules. that are soluble in organic solvents.. The identity of lipids is defined on the basis of a physical property and not by the presence of a particular functional group.. Lipids are relatively insoluble in water.. They are soluble in . nonpolar. solvents such as chloroform , diethyl ether, acetone, benzene and ether.. The hydrophobic (water hating) nature of lipids is due to the predominance of hydrocarbon chain.(-CH2-CH2-CH2-) in their structure. Fats and Oils. Classification of Nutrients. Carbohydrates.

Lipids. are a diverse group of molecules that contain regions composed almost entirely of hydrogen and carbon. All lipids contain large chains of nonpolar hydrocarbons. Most lipids are therefore hydrophobic and water insoluble. Pratt & . Cornely. , . Ch. 8. Lipids and Membranes. There is a lot of important biochemistry of lipids.. We won’t cover it all!.

Lipids are hydrophobic or amphipathic small molecules that may originate entirely or in part by carbanion-based condensations of thioesters (fatty acids, polyketides, etc.) and/or by carbocation-based condensations of isoprene units .

Lipids. : . are a group of naturally occurring substances include a diverse group of organic compounds including . fats, oils, hormones. , and certain components of membranes (. phospholipids. ). All of these substances relatively insoluble in water but soluble in organic solvents like: chloroform, ether and benzene.. Examples of Common Lipids. There are many different types of lipids. Examples of common lipids include butter, vegetable oil, cholesterol and other steroids, waxes, phospholipids, and fat-soluble vitamins. The common characteristic of all of these compounds is that they are essentially insoluble in water yet soluble in one or more organic solvents. .
