Quantitative determination of L-fucose

摘要

A method is provided for the quantitative determination of L-fucose in a sample solution. According to the method an L-fucose dehydrogenase having its optimum pH around neutrality is allowed to act upon the sample solution in the presence or absence of an alpha -L-fucosidase, and the amount of reduced nicotinamide adenine dinucleotide thus formed is measured.
