WebWhenever the lowest priority is going away, the atoms in the front will always be oriented counter clockwise or clockwise. No matter how you move the molecule - highest priority to the front or not, or as in a Newman projection - the rotation of position of 1, 2 and 3 will always be in the same orientation. Comment ( 2 votes) Upvote Downvote Flag WebFischer projections were originally developed by German chemist Emil Fischer for work on carbohydrate (sugar) chemistry. It's a way to quickly draw multiple sugars and compare them since it's easy to spot the asymmetric carbons on a Fischer projection. In fact the example which Jay uses in the video is a sugar called glyceraldehyde (both its ... WebThere are various ways to show these orientations. The solid (dark) “up wedge” I used is certainly common. Some people use an analogous “down wedge”, which is light, to indicate a down bond; unfortunately, there is no agreement as to which way the wedge should point, and you are left relying on the lightness of the wedge to know it is “down”. how to write a catering proposal
