What is acylcarnitine used for?
What is an acylcarnitine profile? An acylcarnitine profile is a blood test used to check for the presence of genetic disorders related to fatty acid oxidation and several organic acidurieas. If a patient is at risk of having these disorders or is suspected of having it, the doctor may order the test.
What is the function of carnitine acyl transferase?
Carnitine acyltransferases catalyze the exchange of acyl groups between carnitine and coenzyme A (CoA).
How is acylcarnitine formed?
Introduction. Acylcarnitines (ACs) are formed from carnitine and acyl-CoAs by carnitine acyltransferases in mitochondria or peroxisomes1,2.
What does acylcarnitine profile test for?
The acylcarnitine profile is a diagnostic test for inherited disorders of fatty acid and branched-chain amino acid catabolism. Patients with this type of metabolic disorder accumulate disease-specific acylcarnitines that correlate with the acyl coenzyme A compounds in the affected mitochondrial metabolic pathways.
What does low Acylcarnitine mean?
Carnitine acylcarnitine translocase deficiency (CACT) is a condition in which the body is unable to break down certain fats.
What does high Acylcarnitine mean?
High levels of C10:2 acylcarnitines can indicate that your child has 2, 4–Dienoyl-CoA reductase deficiency (DE-RED). A positive result does not mean your baby has DE-RED, but more testing is needed to know for sure. What happens next? Your baby’s doctor or a metabolic specialist will help arrange for more testing.
What is carnitine-Acylcarnitine cycle?
Mitochondrial carnitine–acylcarnitine cycle is an important component of carnitine cycle, which consists of carnitine palmitoyl-transferases 1 (CPT1), carnitine palmitoyl-transferases 2 (CPT2), and the transporter protein carnitine-acylcarnitine translocase (CACT), which can uptake fatty acyl-CoAs across the …
Where is carnitine acyl transferase found?
outer mitochondrial membrane
The mitochondrion is the site of the β-oxidation pathway that generates acetyl CoA from fatty acids. Fatty acids, as the CoA derivatives, are transported into the mitochondrion by carnitine acyltransferase located in the outer mitochondrial membrane.
How do you say Acylcarnitine?

What are the symptoms of carnitine deficiency?
Signs and symptoms of primary carnitine deficiency typically appear during infancy or early childhood and can include severe brain dysfunction (encephalopathy), a weakened and enlarged heart (cardiomyopathy), confusion, vomiting, muscle weakness, and low blood sugar (hypoglycemia).
What will happen if someone has carnitine deficiency of carnitine Acylcarnitine Translocase genetic deficiency?
Signs and symptoms of this disorder usually begin soon after birth and may include breathing problems, seizures, and an irregular heartbeat (arrhythmia). Affected individuals typically have low blood sugar (hypoglycemia) and a low level of ketones, which are produced during the breakdown of fats and used for energy.
What does low Acetylcarnitine mean?
Carnitine-acylcarnitine translocase (CACT) deficiency is a condition that prevents the body from using certain fats for energy, particularly during periods without food (fasting).
How do you increase carnitine naturally?
What foods provide carnitine? Animal products like meat, fish, poultry, and milk are the best sources. In general, the redder the meat, the higher its carnitine content. Dairy products contain carnitine primarily in the whey fraction [1,3,5].
What does low carnitine cause?
Carnitine deficiency is a condition where the nutrient can’t reach your body’s cells. It can cause muscle weakness. It may also cause heart and liver problems. With the primary condition, not enough carnitine can get into cells because of a genetic problem.
How do I know if I’m deficient in L-carnitine?
What is carnitine deficiency caused by?
What causes carnitine deficiency? Carnitine deficiency may occur in response to a genetic mutation (gene defect) in the protein responsible for bringing carnitine into the cell (primary carnitine deficiency), or it may occur secondary to other metabolic diseases (secondary carnitine deficiency).
What food is highest in carnitine?
Red meat
Red meat has the highest levels. A 4-ounce beef steak has an estimated 56 mg to 162 mg of carnitine. Carnitine is also found in smaller amounts in chicken, milk and dairy products, fish, beans, and avocado. Vegans tend to get less carnitine from foods, but their bodies usually produce enough anyway.
How do you know if you have a carnitine deficiency?
What are the symptoms of carnitine deficiency?
- Decreased or floppy muscle tone or muscle weakness.
- Tiredness (fatigue)
- Irritability.
- Delayed movement (motor) development.
- Poor feeding in a baby.
- Symptoms of low blood sugar (hypoglycemia) if the liver is affected.
How do you fix carnitine deficiency?
The main treatment for CDSP is L-carnitine supplementation, which is very effective if started before organ damage occurs. Hypoglycemic episodes associated with carnitine deficiency are treated with intravenous dextrose infusion or proper feeding and diet.
What is the primary cause of carnitine deficiency?
Mutations in the SLC22A5 gene cause primary carnitine deficiency. This gene provides instructions for making a protein called OCTN2 that transports carnitine into cells. Cells need carnitine to bring certain types of fats (fatty acids) into mitochondria , which are the energy-producing centers within cells.
How can I get L-carnitine naturally?
Meat, poultry, fish, and dairy products are the richest sources of L-carnitine, while fruit, vegetables, and grains contain relatively little L-carnitine.
How do I know if I have a carnitine deficiency?
Do eggs have carnitine?
The main dietary sources of choline and carnitine are red meat, poultry, fish, dairy products and eggs (yolks).
What happens if you don’t have enough carnitine?
