Abstract
Almost half of biological molecules (proteins and metabolites) are extrapolated as glycosylated within cells. Detection of glycosylation patterns and of attached sugar types is therefore an important step in future glycomics research. We present two algorithms to detect sugar types in Haworth projection, i. e., from x-y coordinates. The algorithms were applied to the database of flavonoid and idcntificd backbonc-spccific biascs of sugar typcs and thcir conjugatcd positions. The algorithms contribute not only to bridge between polysaccharide databases and pathway databases, but also to detect structural errors in metabolic databases.
