Draw the structures of ribose and deoxyribose
Ribose and deoxyribose are both five-carbon sugars. Here are the structures of ribose and deoxyribose:
Ribose:
H OH
| |
H−C−OH−C−OH−C−OH−C−OH−H
| |
OH H
Deoxyribose:
H H
| |
H−C−OH−C−OH−C−OH−C−H
| |
OH H
Note that the only difference between ribose and deoxyribose is the presence or absence of an oxygen atom attached to the second carbon. In deoxyribose, the hydroxyl group (OH) on the second carbon is replaced by a hydrogen atom (H).
What is the difference between the deoxyribose and ribose
The main difference between deoxyribose and ribose is the presence or absence of an oxygen atom on the second carbon of the sugar molecule.
In ribose, the second carbon has a hydroxyl group (OH) attached to it, while in deoxyribose, the hydroxyl group is replaced by a hydrogen atom (H). This small difference in structure gives deoxyribose its name, as it is a ribose sugar lacking an oxygen atom.
This difference in structure is significant because it plays a crucial role in the formation of DNA. Deoxyribose is a key component of DNA (deoxyribonucleic acid), while ribose is a component of RNA (ribonucleic acid). The presence of an oxygen atom on the second carbon in ribose allows for more reactive chemistry, as it can form more bonds, whereas deoxyribose lacks this reactivity.
Overall, the difference between deoxyribose and ribose lies in the presence or absence of the oxygen atom on the second carbon, which impacts their functionality and role in DNA and RNA.
Sure! Here are the step-by-step structures of ribose and deoxyribose:
1. Ribose:
Ribose is a five-carbon sugar, and its structure can be broken down into the following steps:
Step 1: Start by drawing a chain of five carbon atoms in a straight line.
H H H H H
| | | | |
C--C--C--C--C
|
O
Step 2: Attach a hydroxyl group (-OH) to each carbon except the first and last carbon.
H H OH OH H
| | | | |
C--C--C--C--C
|
O
Step 3: Finally, attach a single hydrogen atom (H) to the last carbon.
H H OH OH H
| | | | |
C--C--C--C--C--H
|
O
This is the structure of ribose.
2. Deoxyribose:
Deoxyribose is also a five-carbon sugar, but it differs from ribose by lacking one oxygen atom. Here's how you can draw deoxyribose:
Step 1: Start by drawing a chain of five carbon atoms in a straight line.
H H H H H
| | | | |
C--C--C--C--C
|
O
Step 2: Attach a hydroxyl group (-OH) to each carbon except the first carbon.
H H OH OH H
| | | | |
C--C--C--C--C
|
O
Step 3: Instead of attaching an oxygen atom to the second-to-last carbon, attach a single hydrogen atom (H).
H H OH OH H
| | | | |
C--C--C--C--C--H
|
O
This is the structure of deoxyribose.
