'Hydrophobic tails' presentation slideshows

Chapter 5

Chapter 5. The Working Cell. Cool "Fires" Attract Mates and Meals Living cells put energy to work by means of enzyme-controlled reactions The firefly's use of light to signal mates results from a set of such reactions The reactions occur in light-producing organs at the rear of the insect

Lecture 4 - LIPIDS

Lecture 4 - LIPIDS. General Facts about Lipids. Lipids (fats and oils): These molecules are essentially all hydrophobic or partially hydrophobic. There is quite a variety of structure among the lipids, but the two best known examples are the steroids and the glycerides.
