HBsAg (hepatitis B surface antigen) was the first hepatitis B virus protein to be discovered. [15] It consists of small (S), medium (M) and large (L) protein. [16] HBcAg (hepatitis B core antigen) is the main structural protein of HBV icosahedral nucleocapsid and it has function in replication of the virus. [17]
The structure of hepatitis B virus. Hepatitis B virus (HBV) is a member of the hepadnavirus family. [39] The virus particle consists of an outer lipid envelope and an icosahedral nucleocapsid core composed of core protein. These virions are 30–42 nm in diameter.

HBeAg is a hepatitis B viral protein, produced by the HBcAg reading frame. It is an indicator of active viral replication ; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
Hepadnaviridae [a] is a family of viruses. [2] Humans, apes, and birds serve as natural hosts. There are currently 18 species in this family, divided among 5 genera. [3] Its best-known member is hepatitis B virus.
In histology (microscopic anatomy), the lobules of liver, or hepatic lobules, are small divisions of the liver defined at the microscopic scale. The hepatic lobule is a building block of the liver tissue, consisting of a portal triad, hepatocytes arranged in linear cords between a capillary network, and a central vein.
HBcAg (core antigen) is a hepatitis B viral protein. [ 1 ] [ 2 ] It is an indicator of active viral replication; this means the person infected with Hepatitis B can likely transmit the virus on to another person (i.e. the person is infectious).
The structure consists of a lower stem, a bulge region, an upper stem and a tri-loop. The structure was determined and refined through enzymatic probing and NMR spectroscopy. [2] The closure of the tri-loop was not predicted by RNA structure prediction programs but observed in the NMR structure. The regions shown to be critical for ...
