Question

Describe the lengths of the products of the transketolase reaction when the two substrates are both five-carbon sugars.

Short answer

If the substrates are five carbon sugars, it results in formation of one three-carbon compound and one seven carbon sugars.

Step-by-step solution

Introduction

The pentose phosphate pathway, which contains two stages, oxidative and non-oxidative, is another option for glucose oxidation. The glycolytic reaction is a series of 10 enzyme-catalyzed processes that produces two molecules of pyruvate from one molecule of glucose.

Length of the products of transketolase reaction when both substrates are five-carbon sugars

The C2 unit transfer is catalysed by the transketolase process. Transketolase is a thiamine pyrophosphate cofactor that catalyses the transfer of two carbon units from one of two substrates to a fifth-carbon molecule on another substrate. In this reaction, if both substrates are five carbon sugars, the five-carbon (C5) sugars will produce one three-carbon compound (C3) and one seven-carbon sugars (C7).

Interpretation

Thus, in this reaction, if both substrates are five carbon sugars, the five-carbon (C5) sugars will produce one three-carbon compound (C3) and one seven-carbon sugars (C7).
