The protein coat that constitutes the shell of a virus particle.

[From Latin capsa, box.]


(Animals) any heteropterous bug of the family Miridae (formerly Capsidae), most of which feed on plant tissues, causing damage to crops
[C19: from New Latin Capsus (genus)]


(Biochemistry) the outer protein coat of a mature virus
[C20: from French capside, from Latin capsa box]


(ˈkæp sɪd)

the coiled or polyhedral structure, composed of proteins, that encloses the nucleic acid of a virus. Also called protein coat.
[1960–65; < French capside= Latin caps(a) case2 + -ide -id1]
