Hi

Yes it is branched with 1-4 bonds between molecules for the most part with 1-6 bonds between chains.

Its branching makes it less compact than starch

Yes, definitely branched, allows easier access to glucose in a shorter amount of time,

Yes, it's very branched it has a similar structure to amylopectin. It is more compact than starch :yep:

Isn't it just 1-4 only?

Starch is the one which contains 1-4 and 1-6, (amylose and amylopectin)

Nope, I directly quoted my lecture notes, glycogen has a high number of branching 1-6 bonds

Amylopectin has some 1-6 bonds but is predominantly 1-4
Amylose is entirely 1-4

It's like 9% 1-6 the rest 1-4.

I don't mean to be rude but wouldn't you have found out the answer if you just had a quick flick through your textbook? :s
