Gluconeogenesis: Metabolism of Galactose
About the Lecture
The lecture Gluconeogenesis: Metabolism of Galactose by Kevin Ahern, PhD is from the course Carbohydrate Metabolism.
Included Quiz Questions
Which of the following is true regarding the breakdown of galactose?
- It is converted into an intermediate of glycolysis.
- It is combined with UDP-lactose.
- It requires lactase.
- It produces fructose.
- It first must be recombined with glucose to form lactose.
Which of the following enzymes is NOT matched correctly to the reaction it catalyzes?
- Galactose-1-phosphate uridyl transferase: glucose-6-phosphate + GDP-glucose
- Lactase: lactose → glucose and galactose
- Galactose-1-phosphate uridyl transferase: galactose-1-phosphate + UDP-glucose → UDP-galactose + glucose-1-phosphate
- UDP-galactose-4-epimerase: UDP-galactose → UDP-glucose

Really a great and elaborate presentation. Thanks Prof. Kevin. Now I no longer struggle in cramming Biochemistry but rather find the subject interesting. I wish I started using your lecture guide early in Medical school, but any way not yet late! Thank you once again.
It's unfathomable how much this lecture has saved my time. Though I would appreciate a quick-summary of the products turning into intermediates for other cycles. Like with how g-1-p turns into g-6-p
