New insights into the roles of cysteine and homocysteine in pathological processes

Abstract

Both cysteine and homocysteine are sulfur-containing amino acids with distinct roles in cellular processes. This chapter explores novel perspectives on the roles of cysteine and homocysteine in pathological processes, delving into their intricate involvement in various disease pathways. Additionally, the chapter elucidates the regulatory mechanisms governing homocysteine metabolism and its implications for a range of pathological conditions, including cardiovascular diseases and neurodegenerative disorders. By synthesizing recent research findings, this chapter aims to provide fresh insights into the nuanced interplay among cysteine, homocysteine, and disease progression. The exploration of these sulfur-containing amino acids opens avenues for understanding pathophysiological mechanisms and suggests potential targets for therapeutic interventions.
