Diagram of SARS‐CoV‐2 virus structure. The spike glycoprotein (red) is the protein that binds to the ACE2 receptor of host cells and mediates viral entry. Additionally, this protein is what gives the virus its crown‐like (Latin ‘corona’) appearance. The membrane proteins (yellow) and the envelope small membrane proteins (blue) are important structurally as well as mechanistically. The genomic RNA (white) comprises the genetic material that the virus uses to propagate itself once inside its host.
