Whilst it is generally accepted that glycogen is synthesized from UDPG by the combined action of a chain-lengthening enzyme (glycogen synthase) and a branching enzyme (BE), the synthesis of amylopectinfrom ADPG requires a more complex enzyme system w

The main structural features of glycogen were established many years ago by predominantly chemical methods. However, the fine structure continues to be the subject of experimental investigations by enzymic methods. Current topics include: (a) the mec

Glycogen has been isolated from the livers of rats which had been fasted and then intubated with d -glucose. The structure of the glycogen, as determined by iodine staining and enzymic methods, was shown to be very similar to that from control animal

Methylation and enzymic analysis of various amylodextrin samples shows that a proportion of the molecules, having an average d.p. of ~25, contain two branch-points. This finding is related to the resistance of the amylodextrin to debranching by pullu

A limit dextrinase has been isolated from broad-bean flour and purified 800-fold. The enzyme readily hydrolysed branched α-dextrins containing maltosyl or maltotriosyl side-chains, pullulan, and amylopectin β-limit dextrin. Glycogen β-limit dextri

The structure of isolated barley endosperm cell wall fragments was studied employing malt extracts and two purified endo-(1 → 3)(1 → 4)-β- D -glucanases. The endo-(1 → 3)(1 → 4)-β- D -glucanases were characterised by their activity on vario
