Many of the compounds you mentioned here( e. g choline and cephalin) I got to learn from studying my Scrabble lists, but in this post they came alive as I could see how useful they actually are in real life and how they are connected.

Also, the part about saturated and unsaturated fatty acids and the suffixes in their names, that I never knew. I can go on and on about the things I've learned here, such is the quality of this post. Kudos, or more appropriately KUDOSES.
