Fig. 3From: GC–MS and ADME profile analysis of Carcinoscorpius rotundicauda bioactive compounds and their potential as COVID-19 antiviral3D interaction (surface area interaction) between ligand–receptor. A ACE2; B RdRp; C 3CLpro. The interaction surface area represents when the ligand is at its active site where the receptor in purple tends to be a hydrogen bond donor, while green tends to be a hydrogen bond acceptorBack to article page
