衣壳是病毒的蛋白质外壳,又称为壳体。衣壳是由病毒衣壳蛋白亚基所形成的寡聚体。衣壳的作用是用于包裹病毒的遗传物质(核酸)。

衣壳的类型大致是按它们的形态来分类的。不同的病毒可以具有不同形态的衣壳,大多数病毒的衣壳为二十面体形和螺旋形。但也有少量病毒,如噬菌体的衣壳具有较为复杂的结构,其衣壳类型为复合型。

此外,有些病毒具有包膜,可以将衣壳包裹在其中。

A capsid is the protein shell of a virus. It consists of several oligomeric structural subunits made of protein called protomers. The observable 3-dimensional morphological subunits, which may or may not correspond to individual proteins, are called capsomeres. The capsid encloses the genetic material of the virus.
