¤Acetylcholinesterase (AChE) is an monomeric enzyme. Most often, AChE forms a tetramer and binds with a molecule, collagen Q, to connect to the membrane of the neuromuscular junction. [[2]]. From the (secondary structure), it can be seen that there are 17 and 14 . There are 2 beta sheets formed from 3 anti-parallel and 11 anti-parallel beta sheets, respectively(maybe highlight with green scene). As the shows, turns, alpha helices, and beta sheets all occupy a portion of the exterior of the protein. The means that the turns must be composed primarily of polar side chains. On the other hand, the alpha helices will be amphipathic with side chain order designated by the helical wheel; the exterior will be filled with polar side chains that can hydrogen bond with water while the inside of the alpha helix will have nonpolar, hydrophobic groups. The beta sheets must also be amphipathic, but the pattern of side chains is alternating polar and nonpolar. In addition, in order to maintain its tertiary structure, the protein has two sulfide bonds between CYTOSINE X AND CYTOSINE Y (SHOW DIAGRAM).
