摘要: An almost universal feature of endoparasitic organisms is their dependence upon anaerobic carbohydrate metabolism to obtain energy, regardless the amount environmental oxygen available. Accordingly, a great many parasites store polysaccharides which can be oxidised (though rarely completion) yield ATP. The most common polysaccharide reserve glycogen, occurring in protozoans and helminths alike. Glycogen composed exclusively glucose molecules joined by α-1, 4 6 linkages, ratio 1, 4:1, bonds ranging from 12:1 15:1.
