WHERE TO GO NOW. While R-404A, the most popular refrigerant for commercial supermarket refrigeration, is labeled as needing POE oils, the industry has introduced a range of HFC refrigerants that do work with a range of lubricants, including mineral oil, for specific retrofit applications.
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.uring this process, new capsid subunits are synthesized according to the genetic material of the virus, using the protein biosynthesis mechanism of the cell. During the assembly process, a portal subunit is assembled at one vertex of the capsid.
Terminology â¢ Capsid (syn: coat): regular, shell-like structure composed of aggregated protein subunits which surrounds the viral nucleic acidâ¢â¢ Nucleocapsid (syn: core): viral nucleic acid enclosed by a capsidprotein coatâ¢ Envelope (syn: viral membrane): lipid bylayer containing viral glycoproteins.
