Structure of Glycogens

Biochemical studies follow several themes. For example, investigations can be focussed on the chemical structures of molecules, (for example the structure of glycogen, DNA or protein conformation) or the structural inter-relationship between molecules (e.g. enzymes with their substrates, hormones with their receptors). The other branch of biochemical enquiry is into those numerous dynamic events known collectively as metabolism , defined here as all of the chemical reactions and their associated energy changes occurring within cells . The purpose of metabolism is to provide the... [Pg.1]

The structure of glycogen is similar to that of amylopectin, but with more extensive branching. The highly branched structure of glycogen leaves many end groups available for quick hydrolysis to provide glucose needed for metabolism. [Pg.1139]

Figure 21.6. Structure of Glycogen Phosphorylase. This enzyme forms a homodimer one subunit is shown in white and the other in yellow. Each catalytic site includes a pyridoxal-phosphate (PLP) group, linked to lysine 680 of the enzyme. The binding site for the phosphate (Pj) substrate is shown. Figure 21.6.
