DESCRIBE THE MOLECULAR STRUCTURE 3 types of lipids: GLYCERIDES, PHOSHOLIPIDS, AND STEROLS. DEFINE SATURATED, MONOSATURATED AND POLYUNSATURATED FATTY ACIDS.. LIST CATEGORIES OF LIPIDS BASED ON PHYSICAL STATE AND DIETARY SOURCES. The element Carbon is found in most living organisms.. The study of carbon based molecules is known as Organic Chemistry.. Other key elements in cells are:. Hydrogen, Oxygen, Nitrogen, Phosphorous, and Sulfur. 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.. Definition . Classification of Lipids. Simple lipids. They are esters of FA with various alcohols. D/U the type of alcohols these are subclassified as . Neutral Fats or Oils. Esters of FA with alcohol GLYCEROL. constitute the majority of lipids in the. body. . Triacylglycerols. are the major lipids in fat deposits. and in food, and their roles in lipid transport and. storage and in various diseases such as obesity, diabetes,. 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. 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.. The lipids are a heterogeneous group of compounds, including fats, oils, steroids, waxes, and related compounds, that are related more by their physical than by their chemical properties.. They have the common property of being . 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 .
