Sucrose (beta-D-fructofuranosyl alpha-D-glucopyranoside, 1), methyl alpha-D-fructofuranoside (2), and methyl beta-D-fructofuranoside (3) have been prepared by chemical and/or enzymic methods with single sites of 13C-substitution at C-1, C-2, C-3, and C-6 of the fructofuranosyl ring. 1H (500 MHz) and 13C (75 and 125 MHz) NMR spectra of 1-3 have been(More)
Chronic HBV infection is the leading cause of liver cirrhosis and hepatic cancer, but the individual responses toward HBV infection are highly variable, ranging from asymptomatic to chronic active hepatitis B inflammation.
