Based on these findings, the<br>GlcN levels of milk from other mammals, especially herbivores, were analyzed using the identical high performance<br>ion exchange liquid chromatography as was employed in the previous study. The following mg GlcN/(100 g milk)<br>values were obtained for milk hydrolysates from various mammals: Jersey cow 12; water buffalo 6; goat 10;<br>hippopotamus 19; dog 24; bear 97; giant panda 72; seal 114; and dolphin 94. Additionally, mg GlcN/(g total amino<br>acids), and mg GlcN/100 kcal were calculated. The milk from herbivores contained much lower levels of GlcN than<br>elephant milk. Bear and marine mammals’ milk exhibited moderate GlcN levels, probably because of their low moisture<br>content. Giant panda milk displayed slightly increased GlcN levels and the highest value of mg GlcN/(g total amino<br>acids), and mg GlcN/100 kcal. Free GlcN was not detected in any of the milk samples. The large interspecies differences<br>in milk GlcN concentrations may be related to their ways of li</span> </p> ER -
