![Monosaccharides have the general molecular formula of (CH₂0)m, where m is the number carbons.
(m=5 is a pentose, such as xylose & m=6 is a hexose such as glucose.) Starch is a polysaccharide of
thousands of glucose monomers, linked by an oxygen (-0-) bridge. The general molecular formula
for starch is usually taken as (C6H1005) when n is the degree of polymerization. When formed from
glucose a water molecule is released for every step in the polymerization process; when hydrolyzed
(de-polymerized) a water molecule is necessary. The de-polymerization reaction can be considered
as:
(C6H1005)n + α H₂O → B (C6H1206)
Balance the stoichiometry, i.e., find expressions for a & ß (that may involve the degree of
polymerization, n).
If we start with 1 kg of starch & totally hydrolyze it to glucose then how much glucose do we
get [in kg & kg.mole]? Do the calculations assuming
that n=1,000.
The fermentation of glucose to ethanol can be
expressed in the figure on the right¹. How much
ethanol can be produced from the amount of
glucose found above [in kg & kg.moles]?
Will the molar amounts of glucose & ethanol change
if you assume n=5,000? How about the mass
amounts?
