The different cell membrane transport mechanisms The cell membrane is referred to as a ‘fluid mosaic model’ because the protein part within the cell membrane used to be though of as an even layer spread over the outside and the inside of the phospholipid. Now we are starting to think that it is spread unevenly‚ more like a mosaic than a layer. The phospholipid part of the cell membrane is fluid; this means that its molecules are constantly moving about. Through the molecules constantly moving

Introduction The Diels-Alder Reaction is a reaction used in organic chemistry that builds rings very efficiently (1)‚ this cycloaddition process allows for the stereoselective formation of cyclohexene rings possessing as many as four contiguous stereogenic centers (3). This reaction occurs without intermediates‚ in a single step‚ which explains the stereospecificity due to substituents not being given the chance to “switch around”. (1)These six membered rings are synthesized by reacting a dienophile
