All cells need the amino acid asparagine, and to make it they need the enzyme asparagine synthetase.
This substance is the amino acid, "L"-asparagine.
But dependence upon asparagine does not extend to all types of cancer; it appears to be limited to some forms of leukemia and disease of the lymphatic system.
Meat, egg, dairy nutrient essential for brain development Research indicates that brain cells depend on the local synthesis of asparagine to function properly. "The cells of the body can do without it because they use asparagine provided through diet. Asparagine, however, is not well transported to the brain via the blood-brain barrier," said senior co-author of the study.
