    Influenza hemagglutinin (HA) is a glycoprotein found anchored in the lipid envelope of influenza virus particles which enables the virus to enter its host cell. Hemagglutinin molecules bind sialic acid residues present on a host cell surface, prompting uptake of the virus particle by endocytosis. Upon endosome acidification, the conformation of HA changes such that a fusion peptide becomes exposed, facilitating the fusion of the viral and endosomal membranes.
