Web8. D- or L- Structure: Refers to whether the configuration at the chiral carbon furthest from the carbonyl group for a monosaccharide (for example, highest-numbered stereocenter is C5 of GLC or Fructose) in its open form in the Fischer projection resembles that for R-(+) or L-S-(-)-glyceraldehyde (2,3-dihydroxypropanal), respectively. WebGlucose’s pyranose ring is formed when a hydroxyl group at the 5th carbon position (C-5) of a glucose molecule is reacted with an aldehyde group attached to the 1st carbon position (C-1) of the same glucose molecule. ... the position of the oxygen atom in the ring is 1, which causes confusion. increase.
