Sugar Nutrition UK and water was 'as good as a glucose and water' at maintaining liver glycogen stores during prolonged exercise. Sugar Nutrition UK Sugar Nutrition UK formerly the British Sugar Bureau was a lobby group for the British sugar industry. Dr Alison Boyd is the director of the organisation. She says, in reply to proposals to tax sugar that "Singling out sugar may seem a simple, quick fix solution but risks ignoring many other factors that can contribute to lifestyle diseases.” According to the organisation "Sugar consumption in the UK has declined whilst obesity and diabetes rates have increased".

Glycogen synthase glycogen synthase is highly conserved among species, glycogen synthase likely forms a tetramer in humans as well. Glycogen synthase can be classified in two general protein families. The first family (GT3), which is from mammals and yeast, is approximately 80 kDa, uses UDP-glucose as a sugar donor, and is regulated by phosphorylation and ligand binding. The second family (GT5), which is from bacteria and plants, is approximately 50 kDA, uses ADP-glucose as a sugar donor, and is unregulated. Although the catalytic mechanisms used by glycogen synthase are not well known, structural similarities to glycogen phosphorylase at the catalytic and substrate
