New application of cysteine sulfinic acid, sulfo-alanine and high-sulfo-alanine

The invention discloses a novel application of cysteine sulfinic acid, sulfo-alanine and high-sulfo-alanine. Research finds that CSA, CA and an analogue HCA can specifically inhibit mitochondrial inner membrane ATP/ADP transporter (AAC) protein mediated proton (H +) leakage without affecting ATP/ADP transport, so that energy of a cell mitochondrial electron transport chain (ETC) is converted to ATP generation, heat production is reduced, ATP generation is increased, liver tissue injury repair and regeneration are promoted, and the liver tissue injury repair and regeneration effect is improved. The animal feed conversion rate and the animal movement ability are improved, and the animal heat stress in a high-temperature environment is relieved. The cysteine sulfinic acid, the sulfo-alanine and the analogue high-sulfo-alanine can be used for preparing medicines, foods or feeds for preventing or treating liver injury related diseases, promoting tissue regeneration, reducing heat production of animal bodies, promo
