| 7397639390 | Carbon, Hydrogen, Oxygen (CHO) | *elements that makeup both Carbohydrates and Lipids | 1 | |
| 7355828106 | fats, oils, steroids, phospholipids | the most important lipids | 2 | |
| 7347782788 | Angelina Jolie's LIPS are filled with fat--fatty acids | how to remember fats are a kind of lipid | 3 | |
| 7347756695 | *fatty acid | *monomer of a lipid made of a hydrocarbon chain and a carboxyl group |  | 4 |
| 7347770088 | the reason why a fatty acid is amphipathic | the hydrocarbon chain is nonpolar, while the carboxyl group is polar | 5 | |
| 7347772155 | *amphipathic | *having both hydrophobic and hydrophilc parts | 6 | |
| 7347765612 | lots of energy | how much energy a hydrocarbon chain stores | 7 | |
| 7347796686 | *dehydration synthesis | *the removal of a water molecule to join fatty acids to other molecules (like glycerol) |  | 8 |
| 7347751703 | *triglyceride | *lipid made of three fatty acids attached to a glycerol |  | 9 |
| 7347882054 | glycerol | three carbon alcohol that is hydrophilic |  | 10 |
| 7347808932 | *functions of lipids | *long-term energy storage, insulation, part of the cell membrane, chemical messenger, waterproofing | 11 | |
| 7347816083 | *saturated fatty acid | *fatty acid that consists of all single-covalent bonds between each pair of carbon atoms; each carbon has two hydrogens bonded to it (saturated with hydrogens); | | 12 |
| 7347841101 | food made of saturated fatty acid | animal fats and butter; bad fats | 13 | |
| 7347847726 | unsaturated fatty acids | fatty acid that has one or more double covalent bonds between each pair of carbon atoms; | 14 | |
| 7347857594 | food made of unsaturated fatty acids | plant & fish fats, vegetable oils; good fats | 15 | |
| 7347829600 | *monounsaturated fatty acid | *kind of unsaturated fat that consists only has one double covalent bond (the rest are single) between each pair of carbon atoms |  | 16 |
| 7347833552 | *polyunsaturated fatty acid | *kind of unsaturated fat that has two or more double covalent bonds between each pair of carbon atoms |  | 17 |
| 7347866975 | cis vs. trans fatty acids | if the hydrogen atoms of an unsaturated fat are found on the same side of the double bond, they are known as as cis-isomer. These are nature's lipids. If the hydrogen atoms of an unsaturated fat are found on different sides of the double bond, they are known as as trans-isomer. These are rare in nature. |  | 18 |
| 7347890016 | *phospholipid | *amphipathic lipid made of two hydrocarbon chains, glycerol, and a phosphate group |  | 19 |
| 7358068956 | hydrophobic tail | another name for the hydrocarbon chain in a phospholipid |  | 20 |
| 7358071036 | hydrophobic head | another name for the phosphate group in a phospholipid | | 21 |
| 7347902700 | *the reason a phospholipid is amphipathic | *the hydrocarbon chains (tails) are nonpolar, while the glycerol and phosphate group (head) is polar | 22 | |
| 7347914796 | *phospholipid bilayer | *the main structure of the cell membrane, made of phospholipids that are arranged with the fatty acid tails packed together and the glycerol and phosphate heads facing water in an aqueous solution |  | 23 |
| 7347923212 | micelle | term used to describe the "bubble" formed by phospholipds when placed in an aqueous solution | 24 | |
| 7347949930 | van der walls interactions | weak interaction between nonpolar molecules; holds the hydrophobic fatty acid tails of a phospholipid together | 25 | |
| 7347958901 | reason the phospholipid bilayer is stable | van der waals interactions hold the fatty acid tails together while hydrogen bonding binds the hydrophilic heads with water; also cholesterol is between the fatty acid tails | 26 | |
| 7347930049 | *steroid | *lipid made of four linked carbon rings attached to different functional groups (look like chicken wire fencing) |  | 27 |
| 7347937046 | examples of steroids | cholesterol, sex hormones | 28 | |
| 7358044292 | sex hormones | testosterone, progesterone, estrogen | 29 | |
| 7347941951 | cholesterol | the most common steroid; is a component of the cell membrane as well as the precursor to all other steroids | 30 | |
| 7358055340 | cholesterol vs. testosterone | the tail of cholesterol is replaced with a hydroxyl group |  | 31 |
| 7380811734 | many biologically important molecules are NOT soluble in a lipid, so cell membranes can be selectively permeable | why are lipids good barriers in living organisms? | 32 |
