Sowden and Ivarson (1974) demonstrated that little if any galactosamine is synthesised by fungi during fungi-inoculated incubation experiments.
Glucosamine seems to be more stable than galactosamine and muramic acid, because it occurs in recalcitrant glomaline, a glycoprotein produced in the soil by arbuscular mycorrhizal fungi (Wright and Upadhyaya 1996).
Zhang X, Amelung W (1996) Gas chromatographic determination of muramic acid, glucosamine, mannosamine, and galactosamine in soils.
But there is more to it than just enjoying sufficient glucosamine and galactosamine within your joints.
In basic terms, the electrical charge attaches to glucosamine and galactosamine.
Galactosamine treatment leads to hepatitis associated with necrosis and inflammation, but a high degree of interanimal variation is well known (Vomel and Platt 1986).
Age-dependent phagocytosis of erythrocytes by the isolated perfused rat liver after galactosamine hepatitis and alpha-aphthylisothiocyanate cholestasis.

A more sensitive assay discriminating galactosamine
and glucosamine in mixtures.
05 for carriers) and relatively smaller amounts of the disaccharide sulfated at the C-6 position of the galactosamine unit ([DELTA]Di-6s, -7% for PXE and -6% for carriers) with a significant decrease of nonsulfated disaccharide [[DELTA]Di-Os, -59% (P <0.
Moreover, it has a lower number of sulfated groups in position 6 of the galactosamine and a higher degree of sulfation in position 4 of the same monosaccharide unit.
2008) as well as (b) hepatoprotective activity using Male Sprague-Dawley rats induced with galactosamine
and lipopolysaccharide (Kinoshita et al.
