Glyceraldehyde

Dihydroxyaceton

D-Ribose open chain Fischer + absolute stereo

D-Ribose openchain to alpha / beta D Ribofuranose

D-Ribose openchain to alpha/beta D Ribopyranose (anomereic reference stereocenter configuration?)

D-Arabinose open chain Fischer + absolute stereo

D-Arabinose openchain to alpha / beta D Arabinofuranose

D-Arabinose openchain to alpha/beta D Arabinopyranose (anomereic reference stereocenter configuration?)

Note: L-arabinopyranose is thermodyn favored (= C4 OH axial, C2/C3-OH equatorial!)
Or D-4C1 form
D-Xylose open chain Fischer + absolute stereo

D-Xylose openchain to alpha / beta D Xylofuranose

D-Xylose openchain to alpha/beta D Xyloopyranose (anomereic reference stereocenter configuration?)

(= Glucose without C5-CH2OH)
D-Glucose open chain Fischer + absolute stereo

D-mannose open chain Fischer + absolute stereo

D-Galactose open chain Fischer + absolute stereo

D-Glucose openchain to alpha / beta D Glucofuranose

D-Mannose openchain to alpha / beta D Mannofuranose

D-Galactose openchain to alpha / beta D Galactofuranose

D-Glucose openchain to alpha/beta D Glucopyranose (anomeric reference stereocenter configuration?)

D-Mannose openchain to alpha/beta D Mannose (anomeric reference stereocenter configuration?)

D-Galactose openchain to alpha/beta D Galactopyranose (anomeric reference stereocenter configuration?)

lol kein plan was da mit der schriftart passiert ist. btw: C4 ist (S) confi!
