Lysine has a net positive charge, which makes it one of the three basic (by charge) amino acids. Lysine plays a role in the production of antibodies and lowers triglyceride levels. Lysine is needed for proper growth and bone development in children and to maintain a proper nitrogen balance in adults. Lysine helps in the absorption and conservation of calcium and plays an important role in the formation of collagen, a component of cartilage and connective tissue.
| Micromole per liter | µmol/L = mcmol/L = umol/L = µM/L = mcM/L = uM/L = micromol/L |
| Milligram per liter | mg/L = millig/L = milligram/L = mg/liter |
| Milligram per deciliter | mg/dL = millig/dL = milligram/dL |
| Milligram per 100 milliliters | mg/100mL = millig/100mL = milligram/100mL |
| Milligram percent | mg% = millig% = milligram% |
| Microgram per milliliter | µg/mL = mcg/mL = ug/mL = microg/mL = microgram/mL |
