Question

question
give the molecular formula for erythrulose, the only ketotetrose (a simple sugar that is a ketose and a tetrose).
provide your answer below:

Explanation:

Step1: Recall the general formula for monosaccharides

Monosaccharides have the general formula \(C_nH_{2n}O_n\).

Step2: Determine the value of \(n\)

Since erythrulose is a tetrose, \(n = 4\).

Step3: Substitute \(n = 4\) into the general formula

Substituting \(n = 4\) into \(C_nH_{2n}O_n\) gives \(C_4H_8O_4\).

Answer:

\(C_4H_8O_4\)
