Molecular Mechanism of Absorption, Transport and Metabolic Transformation of Astaxanthin in Aquatic Animals

Résumé fourni par la source

ABSTRACT The global astaxanthin market reached $1.69 billion in 2024, with 47% directed to aquafeed—yet the molecular basis of its absorption, metabolism, deposition, and storage in aquatic organisms remains incompletely resolved. A deeper understanding of these mechanisms will help optimize feed formulations, enhance astaxanthin bioavailability, and improve economic efficiency in aquaculture. This study investigates the absorption mechanisms of astaxanthin mediated by intestinal lipid transporters (SR‐B1, CD36, NPC1L1) and its utilization/deposition in different tissues and organs. It reviews the latest research progress on major absorption pathways, metabolic processes, and storage forms of astaxanthin in aquatic organisms, analyzes key factors affecting its utilization efficiency, and discusses potential future research directions to provide a scientific basis and theoretical support for aquaculture practices.
