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…

1. 2. List which carbohydrates are described as simple and which are complex? Briefly describe the general structures of monosaccharides, disaccharides, and polysaccharides (include the difference between starch and glycogen. Unbranched, occasional branching, and highly branched and how chemical structure effects function). Name the three monosaccharides considered to be important in nutrition, name the three disaccharides commonly found in foods and their component monosaccharides. Then name the foods these sugars are commonly found in (both mono and disaccharides).
Consider these three monosaccharides. H H CH₂OH H- -OH HO H HO H H -OH H OH CH₂OH CH₂OH CH₂OH Part 1 of 3 Which two monosaccharides are stereoisomers? Check two.
