For some viruses, the capsid is surrounded by lipid bilayer that contains viral proteins, usually including the proteins that enable the virus to bind to the host cells. This lipid and protein structure is called the virus envelope, and is derived from the host cell membranes.
A capsid is composed of structural units called capsomeres. Its symmetry may be cubic or helical. A protein coat that covers the nucleoprotein core or nucleic acid (RNA, DNA) of a free virus particle or phage, which may have icosahedral symmetry and itself be enclosed in an envelopeâe.g., Togaviridae.capÂ·sid/ (kapÂ´sid) the shell of protein that protects the nucleic acid of a virus; it is composed of structural units, or capsomers.
