Alcohols Involved In Lipid Structures 3 Alcohols Involved In Various Forms Of Lipids 1 Glycerol C3 Trihydric Alcohol 2 SphingolSphingosine C18 Dihydric Alcohol. Thiols. , Phenols, . And Ethers. IUG, . Fall . 2013. Dr. . Tarek. . Zaida. 1. 1. Alcohols. Alcohols are derivatives of hydrocarbons in which 1 or more of the hydrogen atoms has been replaced by a hydroxyl (-OH) . 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. Learning Objectives:. Know the general formula for alcohols.. Be able to name alcohols.. Describe the shape of alcohols.. Classify primary, secondary, and tertiary alcohols.. Describe the physical properties of alcohols.. Alcohol . – alkyl chain attached to an –OH. . R-OH. Phenol . - aromatic attached to an –OH. Nomenclature. 1. Name the longest chain of carbons which includes the carbon with the hydroxyl group.. PHENOLS. Alcohols and Phenols. Alcohols contain an OH group connected to a . a. saturated C (sp. 3. ). They are important solvents and synthesis intermediates. Phenols contain an OH group connected to a carbon in a benzene ring. 1. Hydration of Alkenes - . addition of water. - uses H. 2. SO. 4. and heat. Ex.; Hydrate propene.. 2. Hydrogenation of Aldehydes & Ketones –. All . carbon-carbon double bonds in the molecule will be hydrogenated at the same time. Fatty Acids. FATTY ACIDS( FAs. ). Class- Derived . Lipids. . BASIC COMPONENT . OF . LIPID FORMS. What are Fatty Acids?. Fatty Acids Are Derived Lipids. Fatty acids are . of Class . Derived . Lipids. nonpolar. organic compound insoluble in polar solvent , but . soluble in organic solvents. such as benzene ,ether, chloroform.. Biological role of lipids. :. Lipids are found naturally in all living organisms.. Cholesterol. Rich in hydrocarbon. Polar group (usually small). Oleic acid. Lipids serve a wide variety of functions. Vitamin K. Surfactants. Protection. Membrane. components. Insulation. Energy storage. st. 1439 . Learning. . Objectives. By the end of this chapter the student will:. . know the structure of alcohol. Knew the different classes of alcohols.. Knew the nomenclature of Alcohols . Knew the physical Properties. . Alcohols contain an OH group connected to a . a. saturated C (sp. 3. ). They are important solvents and synthesis intermediates. Phenols contain an OH group connected to a carbon in a benzene ring. Methanol, CH. are a diverse group of compounds that are insoluble in water but soluble in organic solvents such as ethanol.. The most common types of lipid are . triglycerides. (sometimes known as true fats or neutral fats), but other important lipids include waxes, steroids and cholesterol.. Most of the alcohols are known to be . colourless. liquids or even are said to behave as solid at room temperatures. Alcohols with less molecular weight are said to be highly soluble in water; and with their increase in molecular weight, they tend to become less soluble and their . 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 non-polar organic solvents .
