Question

the end result of hydrolysis is a chain of molecules such as an oligosaccharide. water is needed for hydrolysis to take place. hydrolysis is the process in which plants and animals create complex molecules such as carbohydrates and proteins. 4. what will be the end product(s) of the following dehydration synthesis reaction? c6h12o6 + c6h12o6 + c6h12o6 + c6h12o6 + c6h12o6 → ? o c24h46o23 + h2o o c24h44o22 + 2h2o o c24h42o21 + 3h2o o c24h40o20 + 4h2o 5. which formula represents an oligosaccharide that consists of five monosaccharides joined together by dehydration synthesis? o c6h12o6 o c30h60o20 o 5c6h12o6 o c30h52o26

Explanation:

Step1: Understand dehydration synthesis

Dehydration synthesis is a reaction where water is removed to form a larger molecule from smaller ones. When monosaccharides combine, for each bond formed, one water molecule ($H_2O$) is released.

Step2: Analyze question 4

When three molecules of $C_6H_{12}O_6$ combine by dehydration synthesis, two bonds are formed, so two water molecules are released. The general formula for the reaction of $n$ monosaccharides $C_6H_{12}O_6$ combining is $nC_6H_{12}O_6
ightarrow C_{6n}H_{10n + 2}O_{5n+1}+(n - 1)H_2O$. For $n = 3$, we have $3C_6H_{12}O_6
ightarrow C_{18}H_{32}O_{16}+2H_2O$.

Step3: Analyze question 5

When five monosaccharides combine, four bonds are formed and four water molecules are removed. Each monosaccharide is $C_6H_{12}O_6$. The total number of carbon atoms is $5\times6=30$, hydrogen atoms is $5\times12-4\times2 = 52$ and oxygen atoms is $5\times6-4\times1=26$. So the formula of the oligosaccharide is $C_{30}H_{52}O_{26}$.

Answer:

1. $C_{18}H_{32}O_{16}+2H_2O$
2. $C_{30}H_{52}O_{26}$
