Document Summary
Monosaccharides: stereoisomers, how straight chains form ring structures, drawing sugar structures. If at c1 = aldose, internal = ketose: monosaccharisdes are named depending on number of carbons (triose = 4, pentose = 5, hexose = 6 cs, all other cs have one oh group and 1 or 2 h. Monosaccharides have asymmetric (chiral) carbons: chiral c = any carbon with 4 different groups bonded to it. In sugars that contain many chiral centres, only one that is most distant from. Oh is on the right = d form: steps, find chiral c, determine whether oh is on left or right hand side, aldohexoses give rise to 24 = 16 stereoisomers. Stereoisomers epimers: epimers = 2 sugars that differ only in the configuration around one carbon atom (similar but have only 1 carbon different, these are the most abundant sugars in nature:
