Matching Pairs Lipids part 1Online version lipid structure by Danielle Woods 1 3 characterizations of fatty acids 2 omega-3-fatty acid 3 what are unsaturated fatty acids? 4 lipids 5 what are many lipids comprised of? 6 phospholipids 7 omega-6-fatty acid 8 sterols 9 basic functions of lipids in the body 10 kcals/gram for fat 11 triglycerides 12 what is the degree of saturation of a fatty acid determined by? 13 what are saturated fatty acids? glycerol + three fatty acids, add texture to baked goods, make meats tender, preserve freshness, store as adipose tissue for energy no double bonds, solid at room temperature, have higher melting point stores and provides energy, provides insulation, helps manufacture steroids and bile, plays a role in transporting fat-soluble nutrients in the blood, used to manufacture major sex hormones, key to structure of cell membrane 9 kcals/gram glycerol backbone + two fatty acids + a phosphate group + nitrogen group, hydrophilic on one end & hydrophobic on the other four connecting rings of carbon and hydrogen, do not contain glycerol or fatty acids, do not provide energy category of compounds that include triglycerides, phospholipids, and sterols length of carbon chair, degree of saturation, and shape chain of carbon and hydrogen atoms with a carboxyl group at the alpha end and a methyl group at the omega end a single or double bond first double bond is between 6th and 7th carbons from the omega end double bond(s), liquid at room temperature, have a lower melting point first double bond is between 3rd and 4th carbons from omega end
