Hence, the amounts of hexosamines and muramic acid and their ratios (glucosamine to galactosamine and glucosamine to muramic acid) can serve as useful indicators for bacterial and fungal contribution to SOM (Zhang et al.
In contrast to capillary zone electrophoresis (8, 9), these methods are reportedly not sensitive enough to measure hexosamines in small samples of tissue, and most are not able to separate the glucose-galactose epimers of UDP-hexosamines and UDP-hexoses (9).
In oocytes of the amphibians Bufo arenarum, mannose is the most abundant carbohydrate residue in egg jelly, and it is involved in recognition of sperm (Omata & Katagiri 1996), whereas the sulfated glycoproteins rich in hexosamines, fucose, and galactose found in Xenopus laevis egg jelly act in a similar manner (Yurewicz et al.
