Chapter 25, Problem 39P

Interpretation Introduction

Interpretation:

The mechanism for the reaction of galactose with ATP to form $\text{galactose-1-phosphate}$ should be drawn.

Concept Introduction:

Glycolysis: It is pathway which describes conversion of one molecule of glucose into two molecules of pyruvate.  The series involves 10 reactions.

Galactose: It is a compound with same chemical formula as glucose and it is a naturally occurring monosaccharide.  Glucose and galactose differ in the position of one hydroxyl group.  The metabolism of galactose is done by converting it to $\text{glucose-1-phosphate}\text{and}\text{then}\text{to}\text{glucose-6-phosphate}$

Gluconeogenesis: The reaction in which glucose is synthesised from pyruvate.

$NA{D}^{+}$Molecule: It is the oxidized form of $\text{Nicotinamide adenine dinucleotide }\left(NAD\right)$ which exists in all cells and needed for activation of enzymes.

$NADHmolecule:$ It is coenzyme which gets oxidized on reducing another compound. The oxidized form of $\text{NADH}\text{is}{\text{NAD}}^{\text{+}}$.
