Increased levels of this enzyme may indicate a serious health problem. Elevated aldolase is usually a sign of muscle or liver damage. For example, muscle damage from a heart attack releases aldolase in large quantities. Liver damage, such as hepatitis or cirrhosis, raises aldolase levels as well.
What are aldolase levels?
Generally, the normal range for adults is between 1.0 and 7.5 units per liter. The normal amount of aldolase in the blood is higher in children. For those under age 18, anything under 14.5 units per liter is considered normal.
Can aldolase levels fluctuate?
Aldolase will not change when weakness is caused by neurological problems. Normal ranges may vary slightly based on a particular laboratory’s calibrations. There are also slight differences in normal ranges based on age and gender.
Is there a blood test for muscle damage?
A creatine kinase (CK) test may be used to detect inflammation of muscles (myositis) or muscle damage due to muscle disorders (myopathies) such as muscular dystrophy or to help diagnose rhabdomyolysis if a person has signs and symptoms.
Why is aldolase test done?
Aldolase testing may reveal muscle or organ damage that has occurred due to injury or a condition that affects the muscles or organs. As a diagnostic test, aldolase testing is used with other muscle enzyme tests to help diagnose muscle diseases like muscular dystrophy, polymyositis, and dermatomyositis.
What is the function of aldolase?
Aldolase is a cytoplasmic enzyme involved in glucose and fructose metabolism. It specifically catalyzes the reversible reaction of converting fructose 1,6-bisphosphate into dihydroxyacetone phosphate (DHAP) and glyceraldehydes 3-phosphate. The enzyme works on six reversible reactions in gluconeogensis and glycolysis.
What is another name for aldolase?
Aldolase A (ALDOA, or ALDA), also known as fructose-bisphosphate aldolase, is an enzyme that in humans is encoded by the ALDOA gene on chromosome 16.
What is aldolase deficiency?
Aldolase A deficiency, is an autosomal recessive metabolic disorder resulting in a deficiency of the enzyme aldolase A; the enzyme is found predominantly in red blood cells and muscle tissue.
Is aldolase reversible?
Fructose-bisphosphate aldolase (EC 4.1. 2.13), often just aldolase, is an enzyme catalyzing a reversible reaction that splits the aldol, fructose 1,6-bisphosphate, into the triose phosphates dihydroxyacetone phosphate (DHAP) and glyceraldehyde 3-phosphate (G3P).
How high is too high for creatine kinase?
In rhabdomyolysis, the CK levels can range anywhere from 10 000 to 200 000 or even higher. The higher the CK levels, the greater will be the renal damage and associated complications.
How high are CK levels in polymyositis?
Serum creatine kinase (CK) levels are usually elevated in persons with polymyositis, ranging from 5-50 times the reference range. A level greater than 100 times the reference level is rare. Serum CK levels, along with careful physical examination, may be used to monitor myositis activity.
What does myositis pain feel like?
Myositis is the name for a group of rare conditions. The main symptoms are weak, painful or aching muscles. This usually gets worse, slowly over time. You may also trip or fall a lot, and be very tired after walking or standing.
What is a very high CPK level?
When the total CPK level is very high, it most often means there has been injury or stress to muscle tissue, the heart, or the brain. Muscle tissue injury is most likely. When a muscle is damaged, CPK leaks into the bloodstream. Finding which specific form of CPK is high helps determine which tissue has been damaged.
Does MRI show muscle damage?
An MRI is the best type of imaging for looking at tissue. Your physician may order an MRI on the damaged muscle to find or learn more about your injury. This type of muscle tear imaging can pinpoint the location of even the smallest muscle strains and determine whether a partial or complete strain has occurred.
What blood test shows inflammation?
Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) are blood tests that can be used to check the levels of inflammation in your body.
How long do aldolase test results take?
An aldolase blood test looks for damage to muscles, liver or the heart. Preparation: No special preparation required. Test Results: 1-3 days.
What is the normal range for creatine kinase?
In a healthy adult, the serum CK level varies with a number of factors (gender, race and activity), but normal range is 22 to 198 U/L (units per liter). Higher amounts of serum CK can indicate muscle damage due to chronic disease or acute muscle injury.
What is a normal CPK?
CPK blood tests the different forms of CPK in the bloodstream and the CPK normal range varies from a male to female. The CPK normal range for a male is between 39 – 308 U/L, while in females the CPK normal range is between 26 – 192 U/L.
What are the 10 steps in glycolysis?

- Step 8: Phosphoglycerate Mutase.
What is the function of enolase?
Enolase is a glycolytic enzyme, which catalyzes the inter-conversion of 2-phosphoglycerate to phosphoenolpyruvate. Altered expression of this enzyme is frequently observed in cancer and accounts for the Warburg effect, an adaptive response of tumor cells to hypoxia.
Which aldolase is used in glycolysis?
Aldolase B also known as fructose-bisphosphate aldolase B or liver-type aldolase is one of three isoenzymes (A, B, and C) of the class I fructose 1,6-bisphosphate aldolase enzyme (EC 4.1. 2.13), and plays a key role in both glycolysis and gluconeogenesis.
Where is aldolase found?
Aldolase B is found primarily in the liver, but it is also present at lower levels in kidney and intestinal cells. Aldolase B is involved in the breakdown (metabolism) of the simple sugar fructose, which is found mostly in fruits and is used in the body for energy.
How is aldolase regulated?
Aldolase is regulated by a handful of energy metabolism substrates. These include glucose, lactate and glutamine. When human mast cells are looked at, this enzyme is seen to behave differently. It goes through a post-translational regulation by protein tyrosine nitration.
What class of enzyme is aldolase?
class Lyases Aldolases belong to the class Lyases.
How does aldolase B deficiency cause hypoglycemia?
In individuals deficient in aldolase B activity, this causes an accumulation of fructose-1-phosphate, leading to subsequent inhibition of both glycolytic and gluconeogenesis pathways, thus causing hypoglycemia in individuals.
What are the symptoms of fructose intolerance?
After ingesting fructose, individuals with hereditary fructose intolerance may experience nausea, bloating, abdominal pain, diarrhea, vomiting, and low blood sugar (hypoglycemia). Affected infants may fail to grow and gain weight at the expected rate (failure to thrive).
What does essential Fructosuria mean?
Essential fructosuria is a rare autosomal recessive disorder of fructose metabolism (see this term) caused by a deficiency of fructokinaseenzyme activity. It is characterized by elevated fructosemia and presence of fructosuria following ingestion of fructose and related sugars (sucrose, sorbitol).
Is aldolase A protein?
Aldolase A (ALDOA), Active Protein.
Is fructose bisphosphate aldolase reversible?
Aldolase A (fructose-bisphosphate aldolase A, ALDOA) is a glycolytic enzyme that catalyzes reversible conversion of fructose‑1,6-bisphosphate to glyceraldehyde 3-phosphate and dihydroxyacetone phosphate.
How does aldolase work in glycolysis?
Aldolase is a glycolytic enzyme that catalyzes the conversion of fructose 1-6-diphosphate to glyceraldehyde 3-phosphate and dihydroxy-acetone phosphate via the glycolysis metabolic pathway. The enzyme regulates cell contraction through its reversible binding to these filaments.
