Carbohydrate metabolism

1. CARBOHYDRATE METABOLISM

2. Main pathways of carbohydrate metabolism

Insulin
Glucagon

3.

4. Violations of carbohydrate metabolism Lactose intolerance

5. Violation of glycolysis

Enzyme deficiency
Symptoms
Glucokinase
Hyperglycemia
Increased lipogenesis in adiposities
Overweight
Hexokinase
Low concentration of 2,3-biphosphoglycerate
Increased affinity to oxygen
Abnormal oxygen supply
Muscle
phosphofructokinase
Exercise intolerance
Pyruvate kinase
Hemolytic anemia provoked by oxidants
High concentration of 2,3biphosphoglycerate
Decreased affinity to oxygen
Abnormal oxygen supply

6. Fructose intolerance

7. Galactosemia

Enzyme
Name
Type I Galactose-1-phosphate Classic galactosemia
uridyl transferase
Type II Galactokinase
Galactokinase
deficiency
Type II UDP galactose
Galactose epimerase
epimerase
deficiency
Autosomal recessive
Caused by the deficiency in an enzyme responsible for adequate
galactose metabolism
Toxic levels of galactose-1-phosphate result in hepatomegaly,
cirrhosis, brain damage, cataracts, renal failure, hypoglycemia.
Without treatment, mortality in infants with galactosemia is about
75%.
