Gentiobiose is incorporated into the chemical structure of crocin, the chemical compound that gives saffron its color.
The major active ingredient of saffron is the yellow pigment crocin 2 ( three other derivatives with different glycosylations are known ) containing a gentiobiose ( disaccharide ) group at each end of the molecule.
By 1928, he had deduced and confirmed the structures of maltose, cellobiose, lactose, gentiobiose, melibiose, gentianose, raffinose, as well as the glucoside ring tautomeric structure of aldose sugars.
They are unable to utilize D-maltose, D-trehalose, D-cellobiose, gentiobiose, sucrose, D-raffinose, ?-D-glucose, D-turanose, D-melibose, mannose, galactose, 3-methyle glucose, inosine, D-aspartic acid, glycyl-L-proline, L-alanine, L-arginine, L-serine, pectine, D-saccharic acid, p-hydroxy-phenylacetic acid, methyl pyruvate, citric acid, bromo-succinic acid, acetoacetic acid or propionic acid . " R . lentis " can grow in the presence of the antibiotic compounds lincomycin, tetrazolium violet and tetrazolium blue but not with 1 % sodium lactate, troleandomycin, lithium chloride, potassium tellurite or sodium butyrate.
