Is the one given in TBR for L-Mannose? If I make a gun, carbons 2 and 3 are pointing right and carbons 4 and 5 are pointing left ...
Using your right hand, it should look like this (For left, just the opposite). You want to make sure in both scenarios, the palm of your hand is facing towards you (as if it's a flat fischer projection); basically how it is in the picture:I must be doing something wrong, then ...
D-mannose has the C2 and C3 pointing to the left in the fischer, but if I look at my right palm while doing a gun sign, 4 and 5 are coming toward me (which I thought was "left?")
I'm confused what you're asking. The very last chiral center represents whether it's D or L. If you want the D configuration, use your right hand. If you want the L configuration, use your left hand (or just use right and realize all the chiral centers are inverted).But ... 4 and 5 are coming toward me? LEFT?? Lol, I feel like I'm missing something really simple
