  "Description": "A comprehensive framework for inferring\nmetabolite-mediated cell-cell communication from single-cell\ntranscriptomic data. scMetaLink integrates metabolite\nproduction potential via enzyme expression, metabolite sensing\ncapability via receptor and transporter expression, and\nsecretion potential to construct intercellular metabolic\ncommunication networks. The package leverages the MetalinksDB\ndatabase containing 41894 metabolite-protein interactions\ncovering 1128 metabolites and 4374 proteins. Key features\ninclude probabilistic inference of metabolite production,\nreceptor-mediated metabolite sensing quantification,\npermutation-based statistical testing with multiple hypothesis\ncorrection, pathway-level aggregation analysis, and\npublication-ready visualization.",
