how do you think carbohydrate strands are arranged in agar

[kateaugu]

any opinions

[Black Cat.1]

agar is composed of pectin structures in a branched, kinda spiralling arrangement. similar to glycogen, yet less branched and more globular in comparison to it. It is also less dense, allowing for substances to diffuse through it - namely auxins and other plant hormones. it is made up of strands of linear carbohydrate chains called agarose chains (their made of tonnes of monosaccharides - quite unusual of most carbs, but its true ) hope that helps. i doubt ull need to know anymore than that

Carbohydrate in Agar??   What was the original question.  Sounds like a Gel Electrophoresis question to me.  Gel Electrophoresis is a bit like chromatography.  You put a mix of things in at one end and the shorter (Gel elec) or the lighter (Chromo) move further than their longer/heavier counterparts.  you use it to sort lengths of protein, DNA etc.     Thats really Unit 4 though - shouldn't be coming up yet in Unit 3.
