Acylcarnitine assay

Acylcarnitine assay

Understand energy homeostasis across generations

Acylcarnitines play an exceptional role in the understanding and diagnosis of inborn errors of metabolism. A growing body of evidence puts acylcarnitines now in the spotlight of uncovering mechanisms of aging and age-related diseases. Acylcarnitines and their regulation are the missing piece between cellular malfunction and physiological outcome – a set of universal markers for energy homeostasis across generations.

Understand energy homeostasis across generations

Acylcarnitines play a vital role in energy production and metabolism. Studying them can help us understand and diagnose inborn errors of metabolism and explore mechanisms of aging and age-related diseases. Acylcarnitines are the missing link between cellular malfunction and physiological outcome – a set of universal markers for energy homeostasis across generations.

Acylcarnitines in health and disease

Analysis of acylcarnitines is a go-to check when screening blood for inborn errors of metabolism. There is also growing interest in how acylcarnitines can help to understand and diagnose other metabolic diseases, such as certain types of cancer, cardiovascular diseases and neurological disorders.

Many diseases are associated with changes in acylcarnitine metabolism

  • Alzheimer´s disease
  • Depression
  • Hepatocellular cancer
  • Cardiovascular disease
  • Liver disease (NASH)
  • Newborn screening


Role of acylcarnitines in cellular and systemic metabolism

Acylcarnitines’ role in both, glucose and fatty acid metabolism

  • Regulate beta-oxidation
  • Maintain the balance between beta-oxidation and glucose oxidation
  • Involved in metabolism of branched chain amino acids (BCAA)
  • Involved in production of ketone bodies
acylcarnitine pathways

How to read mitochondrial metabolism from plasma.

Mammals get fatty acids through their diet, when fat is broken down during digestion. Albumin transports fatty acids to cells, where they conjugate with Coenzyme A to form Acyl-CoA. Acyl-CoA can either be used in beta-oxidation inside mitochondria or, depending on the current metabolic situation and mitochondrial status, conjugated with carnitine to form acylcarnitine. Excess acylcarnitines are released into the bloodstream, acting as a regulator of glucose metabolism.
