Natural products with both linear (in red) and circular (in blue) sugars in their structure. a 5-({6-[2-(3,4-Dihydroxyphenyl)-5,7-dihydroxy-4-oxo-4H-chromen-8-yl]-3,4,5-trihydroxyoxan-2-yl}methoxy)-3-hydroxy-3-methyl-5-oxopentanoate contains an acidic sugar (in red) and a simple circular sugar (in blue). b 5-O-[(3β,5ξ,9ξ,16α)-3-{[6-Desoxy-3-O-(β-d-glucopyranosyl)-β-d-galactopyranosyl]oxy}-16,23,28-trihydroxy-29-oxooleana-11,13(18)-dien-29-yl]-d-ribitol with two terminal ring sugars (in blue) connected between them and to the aglycon with glycosidic bonds and a terminal linear sugar alcohol. c 7,8-Dimethyl-10-(2,3,4-trihydroxy-5-((3,4,5-trihydroxy-6-(hydroxymethyl)tetrahydro-2H-pyran-2-yl)oxy)pentyl)benzo[g]pteridine-2,4(3H,10H)-dione contains a terminal circular sugar (in blue) and a non-terminal sugar alcohol (in red)
