Homocysteine
Definition
Homocysteine is an amino acid in the blood that is mostly sourced from eating meat, and its levels are influenced by diet, genetic factors, and lifestyle. High levels may be associated with certain health conditions.
Scientific / Technical Definition
Homocysteine is a non-proteinogenic amino acid that forms as an intermediate in the metabolism of methionine and cysteine. It is involved in the body's methylation cycle. Elevated homocysteine levels are considered a risk factor for cardiovascular diseases and may result from deficiencies in vitamins B6, B12, and folate.
Benefits
- Helps in assessing cardiovascular health risks.
- Can be an indicator for vitamin deficiencies.
- Monitoring levels aids in managing homocystinuria, a metabolic disorder.
Examples
- Meat (particularly red meat)
- Eggs
- Dairy products
Additional Information
- Importance: Maintaining normal homocysteine levels during pregnancy is crucial as elevated levels are linked to complications such as pre-eclampsia and increased risk of neural tube defects.
