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. Fats, Phospholipids, . and Sterols. CHAPTER 5: LIPIDS: OILS, FATS, PHOSPHOLIPIDS, . AND STEROLS. At the end of this chapter, you should be able to:. Discuss benefits and risks associated with dietary . Learning Objectives. Learn what a triglyceride is.. Learn what a fatty acid is.. Learn the structure of a . phospholipid. .. Learn how lipids are tested for.. What is a lipid?. Like most other biochemical substances, lipids contain . One of a group of compounds, including fats, phospholipids & steroids, that mix poor, if at all, with water . What are lipids?. Provides essential fatty acids-which your body cannot manufacture. Maintenance of healthy skin. CHAPTER 10. UNIT. TARGETS. 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. Lipids are a family of chemical compounds that are a main component in every living cell. They include the following three categories:. Triglycerides. – they include all fats and oils people typically eat.. Carbohydrates and Lipids . (Ch. 5-1 and Ch. 5-2). Describe the properties of the monomers and the type of bonds that connect the monomers in biological macromolecules.. Explain how hydrolysis and dehydration synthesis are used to cleave and form covalent bonds between monomers.. 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.. are a large and diverse group of naturally occurring organic compounds that share some general . properties. ..
