Homocysteine is the predecessor to cysteine based on its involvement in the metabolic pathway of methionine. Factors like lifestyle habits, nutritional status, and chronic disease states can lead ...

It also enables hormone metabolism, cellular energy production, ... Its active form facilitates the conversion of homocysteine to cystathionine, an alternative pathway for homocysteine clearance.

Decreased levels of vitamin cofactors such as vitamins B6 and B12 and folate, which are essential to the folate-methionine metabolic pathway, can also increase homocysteine levels.

Since homocysteine is a natural part of the body's metabolism, the researchers wanted to investigate metabolic pathways involving homocysteine in both rodents and humans with glaucoma.
