Organic chemistry and especially biochemistry are the areas of chemistry that use the Haworth projection the most.
How can I convert d-altrose bond line view to Fischer projection?
WebDie Haworth-Projektion ist eine chemische Darstellungsweise von Molekülen, die nach dem Chemiker Walter Norman Haworth benannt wurde. Bedingung für diese Darstellungsweise ist das vorkommen von ringförmigen Partien innerhalb des Moleküls. Die Ringe selbst bestehen dabei aus fünf oder sechs Atomen. WebIn a Haworth projection formula, a cyclic hemiacetal or hemiketal is represented as a planar structure and viewed edge-on. Bond lines representing atoms toward the viewer are written as heavy wedges; bond lines away from the viewer are written as ordinary bond lines. The carbon atoms are arranged clockwise with C-1 of the pyranose of an ... raw beauty kaitlyn bristowe
