| Plant fat is mostly | unsaturated and liquid at room temperature |
| Animal fat is mostly | saturated and solid at room temperature |
| Trans fat is bad | used because it has higher melting point and a longer shelf life |
| Function of fats | longterm storage of energy, insulation, and function of nervous system |
| Phospholipids has a | phosphate and a glycerol and 2 fatty acids |
| Functions of phospholipids | a major component of cell membranes |
| Steroid | lipid that has 4 rings of carbon. Building block of steroid is cholesterol. |
| Cholesterol | Building block of steroid |
| Examples of steroids | testosterone, estrogen, and cortisol |
| Amino acids | are the building blocks of proteins |
| Primary Level of conformation in proteins | exact same sequenc of amino acids |
| Secondary Level of conformation in proteins | Take polypeptide chain and either make an alpha-helix or make a beta pleated sheet. |
| Alpha-helis (collagen and wool) | the hydrogen bonds are in the loops. |
| Beta-pleated sheat (silk and spider web) | hydrogen bonds are inbetween the sheets |
| Tertiary | take alpha -helix or beta-pleated sheet and fold it back on itself and stabilize it |
| Quaternary | 2 or more polypeptides (hemoglogin is an example) |
