Document Summary

Lecture 1: biological lipids structures and functions. C-c bonds are all rotatable but turns out that under most conditions saturated fatty acids have anti conformation. The terminal ch3 and ch2 (n) groups are 180 c, i. e. trans from each other. Anti is the lowest energy state (minimizes steric clashing: angles between the bonds shown in the last diagram on the right, nomenclature how to name saturated fatty acids, method 1: carbon skeleton. Determine # of c: double bond ratio. In saturated, we have #c: 0 (no double bonds in saturated fatty acids!: method 2: systematic name. Determine # of c and name acid accordingly using chemistry prefixes. The n represents normal meaning that it is a linear chain, i. e. no branching: method 3: common name. To name, start counting from carboxyl acid end (***) Count down for the # of c and then count the number of double bonds. Mostly unsaturated fatty acids: butter soft at room temp.
