| differences between archaea's phospholipids vs. bacteria? |

| Omega-3/Omega-6 |
when there are lots of double bonds in a fatty acid (polyunsaturated), they are counted from the end (the right side). if first double bond is on the 3rd Carbon, it's an Omega-3; if the first one is on the 6th carbon, it's an Omega-6.
