Glucose; starch is composed of two polymers actually, the linear amylose (alpha -1-4 linked Glc) and amylopectin (short chains of alpha 1-4 linked glucose with ramification at 1-6). As to how to determine the repeating units and structure, it was done in the 1970's using acidic and enzymic hydrolyses. And of course extensively confirmed since.

Hi Catherine M G C Renard

That was so precise. Thanks very much, indeed confirming it. It was awesome. I'll look at it, though for sure.

Thanks so much, again
