What is the structure of hemagglutinin?

Hemagglutinin consists of a globular head and a stem. The globular head consists of three chains, Chains A, C, and E. The stem of the protein consists of three chains as well, Chains B, D, and F.

Why is it called orthomyxovirus?

Classification. The family Orthomyxoviridae comprises the genera Influenzavirus A, Influenzavirus B, Influenzavirus C, Thogotovirus, Quaranjavirus, and Isavirus. The name of the family is derived from the Greek myxa, meaning mucus, and orthos, meaning correct or right.

What is the classification of influenza virus?

Influenza A viruses are classified by subtypes based on the properties of their hemagglutinin (H or HA) and neuraminidase (N or NA) surface proteins. There are 18 different HA subtypes and 11 different NA subtypes. Subtypes are named by combining the H and N numbers – e.g., A(H1N1), A(H3N2).

What is the structure of Tamiflu?

C16H28N2O4Oseltamivir / Formula

What is the function of hemagglutinin?

The hemagglutinin(HA) of influenza virus is a major glycoprotein and plays a crucial role in the early stage of virus infection: HA is responsible for binding of the virus to cell surface receptors, and it mediates liberation of the viral genome into the cytoplasm through membrane fusion.

What does hemagglutinin mean?

hemagglutinin, any of a group of naturally occurring glycoproteins that cause red blood cells (erythrocytes) to agglutinate, or clump together. These substances are found in plants, invertebrates, and certain microorganisms.

What are the characteristics of Orthomyxovirus?

orthomyxovirus, any virus belonging to the family Orthomyxoviridae. Orthomyxoviruses have enveloped virions (virus particles) that measure between 80 and 120 nm (1 nm = 10−9 metre) in diameter. The nucleocapsid, which consists of a protein shell, or capsid, and contains the viral nucleic acids, has helical symmetry.

What are 5 influenza types?

There are four main influenza viruses (A, B, C, D), with A and B strains causing flu outbreaks every year. Read more about the different types of flu, the flu vaccine, and other ways to protect yourself from getting sick with the flu this year.

What are the 3 types of influenza?

What Are the Different Types of Flu? There are three types of flu viruses: A, B, and C. Type A and B cause the annual influenza epidemics that have up to 20% of the population sniffling, aching, coughing, and running high fevers. Type C also causes flu; however, type C flu symptoms are much less severe.

How many sp2 atoms are in Tamiflu?

More specifically, benzaldehyde contains 7 sp2 hybridized carbon atoms.

What is the medical name for Tamiflu?

Oseltamivir is used to treat symptoms caused by the flu virus (influenza). It helps make the symptoms (such as stuffy nose, cough, sore throat, fever/chills, aches, tiredness) less severe and shortens the recovery time by 1-2 days.

What compounds are subject to specialized nomenclature rules?

Many compounds containing three or more elements (such as organic compounds or coordination compounds) are subject to specialized nomenclature rules that you will learn later.

Are there any exceptions to the general naming method of oxyacids?

There are some exceptions to the general naming method (e.g., H 2 SO 4 is called sulfuric acid, not sulfic acid, and H 2 SO 3 is sulfurous, not sulfous, acid). Table 8. Names of Common Oxyacids

Why is hydrogen not specified in the IUPAC nomenclature system?

Since hydrogen is such a common component of organic compounds, its amount and locations can be assumed from the tetravalency of carbon, and need not be specified in most cases. The IUPAC nomenclature system is a set of logical rules devised and used by organic chemists to circumvent problems caused by arbitrary nomenclature.

How do you name Binary compounds with monatomic ions?

The name of a binary compound containing monatomic ions consists of the name of the cation (the name of the metal) followed by the name of the anion (the name of the nonmetallic element with its ending replaced by the suffix – ide ). Some examples are given in Table 1. Table 1.
