How many carbons are in amylopectin?

Answer 1

Very, very many. Amylopectine is a carbohydrate polymere made of glucose (C6H12O6) units:

(n+1) C6H12O6 --> (C6H10O5)n(C6H12O6) + n H2O (with n >> 1000)

So, depending on 'n' there are 6*(n+1) Carbon atoms in it, relatively 40% by number, about 7.5% by mass.

Answer 2

Amylopectin is a branched polymer of glucose, similar to amylose, but with additional branching points. It consists of many glucose units linked together, and the number of carbons can vary depending on the length of the polymer chain. However, each individual glucose unit in amylopectin contains six carbons.
