Which of the following secondary structures would you expect to find on the surface of a globular protein? Alpha helix Beta sheet a, b, and c if the polar and charged amino acid side chains face the surface of the protein. Loops between two alpha-helices

Your friend has discovered a protein that they suspect is glycosylated. They decide to perform a series of tests to determine the nature of the oligosaccharide. Assuming/Knowing the following: Fucose molecular weight is approximately 164 Galactose molecular weight is approximately 180 GalNAc molecular weight is approximately  221 Mannose molecular weight is approximately 180  Sialic Acid molecular weight is approximately 309 Neuraminidase cleaves before a Sialic Acid (Sialic Acid and anything after leaves the protein) Beta-galactosidase cleaves after a Galactose (Galactose and anything before remains on the protein) Peanut Agglutinin binds to GalNAc Concanavalin A binds to Mannose Hemagglutinin binds to Sialic Acid Based on preliminary results, they suspect that the oligosaccharide is 7 glycosides long and weighs a total of 1414 g/mol They carried out the following experiments: they treated the protein with either a glycosidase or a lectin, and then pelleted the protein using…
