Answer 1

11. Antibodies are characterized as ____ O-linked; asparagine __ and possess oligosaccharides bonded to which amino acid?

• O-linked glycans attached to the hydroxyl oxygen of serine, threonine, tyrosine, hydroxylysine, or hydroxyproline side-chains, or to oxygens on lipids such as ceramide

12.  E. glyconucleotide.

In Gram-positive bacteria and Gram-positive archaea (Fig. .... The bacterium possesses a unique Gram-negative cell envelope with a glycosylated ... cycle, with the glycan moieties protruding from the cell surface into the exterior environment (Fig. ..... Also, both glycans contain a deoxyhexose residue in their linear structure.
