Hi there!
Is anyone able to explain how the different polysaccharides such as amylose, amylopectin, glycogen (energy storage) and cellulose (structural) polysaccharides can be formed from the same monomer and how their structure helps in biological function??
Im stuck! Many thanks, Laura

well, i don't know the details (do you need details for the exam???), just use common sense
it's like with any process, not only with polysccharides
when there is a substrate accumulation occures it activates sertain enzymes that promote formation of certain product
in different conditions that dictate body's need for a certain product at a time we have different ezymes (and hormones) working on it's substrate and if substrate is not there or enzyme is not there - there goes pathology (deficiency state or storage disease, etc).
if you need percise answer - go Google, best place for me to find any answer
good luck

Polysaccharides are of two types
1- HOMOPOLYSACCHARIDES that contain same polymers. They include Starch a plant polysaccharide, Glycogen an animal polysaccharide. Both of them can be digested by Humans, and a cellulose that can't b digested by Humans because they lack the enzyme cellulase
2 - HETEROPOLYSACCHARIDES that contain different polymers. They are subdivided in to two other types
a) Mucopolysaccharides that includes mucoproteins i-e Hyaluric acid etc
and
b) Mucilages that inculdes agar used for culturing of microorganisms :nod
