Document Summary
In this video, we"d like to continue discussing enzymes. 1191 particular, we want to focus on the mechanisms whereby an enzyme will reduce the activation. And then we"ll end up talking a little bit about protein folding. 1193 [00:00:18. 04] in this first slide, we see in blue an enzyme called lysozyme which acts upon. 1194 polysaccharides which are strings of sugars which are shown in red. And here you can see some of the detail. 1196 have a glycocidic bond between two sugar molecules. 1197 and aspartic acid-- making a simultaneous attacks on the glycosidic bond proceeding to a. 1199 [00:01:04. 10] and then we have hydrolysis of a water molecule adding a proton to the glutamic. 1200 acid and putting a hydroxyl group on the carbon cleaving this ester bond which is an. And that"s pretty nice, but i feel it"s still fairly complicated. 1202 build your intuition about a kind of enzyme mechanism.
