Lipids 0.0 / 5 ? BiologyBiological moleculesASOCR Created by: GeorgiaWivsCreated on: 11-11-16 11:53 Lipids contain three main elements Carbon, Hydrogen and Oxygen 1 of 14 Lipids consist of two types of molecules Glycerol head and Fatty Acid tail 2 of 14 1 FUNCTION OF A LIPID: Energy source, can be respired to make ATP and stored in adipose cells 3 of 14 ANOTHER FUNCTION OF A LIPID: Insulation, such as blubber in whales, and electrical insulation around nerve cells. 4 of 14 What is glycerols structure? 3 Carbon Atoms, each has an OH group attached 5 of 14 What is the structure of a Fatty acid? Fatty acid chains are hydrocarbons with carboxyl chains on one end 6 of 14 What do fatty acids control? This allows fluidity to be controlled depending on the number of saturated and unsaturated chains. 7 of 14 Whats the structure of an unsaturated bond? Unsaturated (single C-C bond) 8 of 14 Whats the structure of an saturated bond? -Saturated (one double C=C bond) 9 of 14 Whats the structure of triglyceride? Glycerol + 3 Fatty acid chains 10 of 14 How are ester bonds form? A Condensation reaction between OH group of glycerol and OH group of the fatty acid. 11 of 14 Triglycerides are Hydrophobic (insoluble). 12 of 14 What is the structure of a Phospholipid? Glycerol + 2 Fatty acid chains + Phosphate group 13 of 14 Triglycerides have a ? head and ?tail Phosphate head = hydrophilic and a Fatty acid chain = hydrophobic. 14 of 14
