What is the product of fructose metabolism via glycolysis?
What is the product of fructose metabolism via glycolysis?
Fructose 1-phosphate is then converted into the trioses dihydroxyacetone phosphate and glyceraldehyde via aldolase B. Aldolase B also functions in the liver for normal glycolysis (glucose metabolism). Glyceraldehyde is then converted to glyceraldehyde-3-phosphate via triokinase.
What are the products of fructose metabolism?
The products of fructose metabolism are liver glycogen and de novo lipogenesis of fatty acids and eventual synthesis of endogenous triglyceride.
What is the product of reduction of galactose?
Galactose can be converted to glucose-6-P, after which it can be used for glycogen synthesis; or it can be oxidized further to form PYR or acetyl-CoA for additional energy generation or fatty acid synthesis.
What are the by products of glucose metabolism?
Glucose (blood sugar) is distributed to cells in the tissues, where it is broken down via cellular respiration, or stored as glycogen. In cellular (aerobic) respiration, glucose and oxygen are metabolized to release energy, with carbon dioxide and water as endproducts.
Where are fructose and galactose metabolized?
In the liver, galactose is converted to glucose-6-phosphate in order to enter the glycolytic pathway. Fructose is converted into glycogen in the liver and then follows the same pathway as glycogen to enter glycolysis.
How is galactose metabolized?
Although glucose is the form of sugar stored as glycogen within cells, galactose is utilized via conversion to glucose, which can then be oxidized in glycolysis or stored as glycogen. Indeed, up to 30% of ingested galactose is incorporated into glycogen.
What product is formed when both ends of glucose are oxidized?
Glucose can be oxidized to give three different acids. The enzyme glucose oxidase gives rise to gluconic acid and H2O2. Cupric ions and ferricyanide ions also oxidize glucose to gluconic acid. Glucuronic acid is the monomeric component of pectin and occurs mostly as the methyl ester (methylated pectin).
What are the three products obtained upon metabolism of glucose?
Glucose is oxidized during glycolysis, creating pyruvate, which is processed through the Krebs cycle to produce NADH, FADH2, ATP, and CO2. The FADH2 and NADH yield ATP.
What are the final products of glycolysis?
The final product of glycolysis is pyruvate in aerobic settings and lactate in anaerobic conditions.
What does fructose galactose make?
Table of Common Disaccharides
| Dissacharide | First Unit | Second Unit |
|---|---|---|
| sucrose | glucose | fructose |
| lactulose | galactose | fructose |
| lactose | galactose | glucose |
| maltose | glucose | glucose |
What are the products glycolysis?
1: Glycolysis produces 2 ATP, 2 NADH, and 2 pyruvate molecules: Glycolysis, or the aerobic catabolic breakdown of glucose, produces energy in the form of ATP, NADH, and pyruvate, which itself enters the citric acid cycle to produce more energy.
