Question
Chapter 22, Problem 22.83GP
Interpretation Introduction
Interpretation:
The major food sources of galactose in the diet has to be identified.
Concept Introduction:
Galactose is a simple sugar it founded in milk; it is one of the monosaccharide (like simple carbohydrate). It is rarely found in nature or in foods as it is commonly found linked with glucose, forming the disaccharide lactose.
Galactose pathway
- Galactose is a monosaccharide
- The lactose is sugar that is found in many foods, when the lactose is broken down in the body, glucose and galactose are produced.
- Galactose is converted into glucose in the body for energy purpose in the Leloir pathway.

All of the following statements about glucose are true except:
Glucose is metabolized in the cytoplasm of prokaryotic organisms.
On a low-carb diet, keto acids from glucogenic amino acids will be used to synthesize glucose.
Glucose is metabolized in the mitochondria of mature red blood cells.
Under non-starvation conditions, the brain relies exclusively on glucose as its fuel source.
Lactose is found in milk products. It is converted by the body into a usable form in a series of chemical
reactions. The diagram shows the series of reactions that convert lactose into a usable form.

Glucose 6-phosphatase allows cells to trap glucose in the cell; however, these tissues primarily rely on noncarbohydrate energy sources. Glucose 6-phosphatase allows cells to generate glucose through gluconeogenesis; however, gluconeogenesis only takes place in the liver. Glucose 6-phosphatase allows cells to release glucose into the blood; however, these tissues should never release glucose. Glucose 6-phosphatase provides glucose 6-phosphate for glycogen synthesis; however, these tissues do not need glycogen.arrow_forward
