Witryna23 lip 2024 · To begin, start by drawing two lines that are parallel to each other but not perfectly horizontal, as shown here. Next, add a downward-pointing V tip to one end (this is the tail of the chair). Finally, add an upward-pointing V tip to the other end (this is the nose of the chair). The steps involved in drawing the chair conformation of cyclohexane. Witryna25 sty 2024 · Starting with a Fischer projection, it’s not too hard to convert it to a Haworth once you know a few tricks. For C-2, C-3, and C-4, if the OH is on the right hand side of the Fischer, it will be down in the Haworth. If it is on the left hand side of the Fischer, it will be up in the Haworth. If the sugar is D, draw the C-5 CH 2 OH pointing up.
