Q. 16.39 - An Introduction to General, Organic, and Biological Chemistry

Question

What are isoenzymes?

Step-by-Step Solution

Answer

(1) ${\mathrm{LDH}}_1$ found in heart, kidney.

(2) ${\mathrm{LDH}}_2$ found in RBC, heart, brain.

(3) ${\mathrm{LDH}}_3$ found in Brain, lungs, WBC.

(4 )${\mathrm{LDH}}_4$ found in lung. skeletal muscles.

(5) ${\mathrm{LDH}}_5$ found in skeletal muscle, liver.

Step 1: Introduction

Isoenzymes are enzymes that have different forms that catalyse the same reaction in different cells or tissues of the body.

Step 2: Given information

As an example:

Lactate dehydrogenase has five isoenzymes that catalyse the conversion of lactate to pyrulate.

Step 3: Explanation

(1) ${\mathrm{LDH}}_1$ tound in heart, kidney.

(2) ${\mathrm{LDH}}_2$ found in RBC, heart, brain.

(3) ${\mathrm{LDH}}_3$ found in Brain, lungs, WBC.

(4) ${\mathrm{LDH}}_4$ found in lung. skeletal muscles.

(5) ${\mathrm{LDH}}_5$tound in skeletal muscle, liver,
