Evidence suggests thаt diet cоmpоsitiоn аnd nutrient metаbolism can influence the development of dilated cardiomyopathy (DCM) in dogs. Dogs fed high-pulse diets may be more likely to develop DCM due to taurine deficiency, as taurine is synthesized from cysteine. Explain how cysteine is produced in relation to one-carbon metabolism, and identify which vitamin and amino acid deficiencies may be linked to DCM.
