Lysine (Lys) Unit Converter
Lysine (Lys) is an essential amino acid, meaning it must be acquired entirely through diet. It plays a foundational role in human physiology, being crucial for protein synthesis, the absorption of calcium, and the production of hormones, enzymes, and antibodies. Lysine is also key to the formation of collagen, a vital component of connective tissue.
Clinically, Lysine levels are monitored in amino acid analysis. Highly elevated levels (Hyperlysinemia) are caused by rare genetic defects in Lysine metabolism. While often benign, severe cases can be associated with neurological complications. Deficiency is rare but can impact growth and immune function. This converter facilitates accurate switching between the conventional mass unit (mg/dL) and the International SI unit (μmol/L).

Clinical Context
Reference Range (Fasting): Plasma Lysine levels are typically maintained around 80–250 μmol/L.
Hyperlysinemia is diagnosed by markedly elevated levels, usually greater than 600 μmol/L. The conversion factor relies on MW 146.19 g/mol: 1 mg/dL ≈ 68.40 μmol/L.
