Homocysteine a Biomarker and Its Impact on Health

Homocysteine (Hcy) is a sulfur-containing amino acid that is a nonessential amino acid for bodily functions and is produced from methionine. It serves as an intermediary compound in the biosynthesis of methionine and cysteine.
Methylation is a universal biochemical process that covalently adds methyl groups to a variety of molecular targets, including neurotransmitters, lipids, proteins, and DNA.
Typical homocysteine levels range from 5 to 15 micromoles per liter (µmol/L).
Levels between 15 and 30 µmol/L are considered moderately high.
Levels above 30 µmol/L are considered very high.
Homocysteine is an indicator of 100+ medical conditions
