Antibodies are characterized as and possess oligosaccharides bonded to which amino acid?

Out of the following given choices;

A. O-linked; serine

B. O-linked; asparagine

C. O-linked; threonine

D. N-linked; glutamine

E. N-linked; asparagine

The answer is B. O-Linked referred to type of glycosylation of the proteins. This type of glycosylation involves attachment of a monosaccharide or an oligosaccharide molecule to an oxygen atom in an amino acid residue of proteins. While N-linked glycosylation is an attachment of an oligosaccharide molecule to an amide nitrogen atom of arginine or asparagine of proteins. Glycosylation (a post-transcriptional modification) is a bond formed from donor of a glycosyl group (usually a carbohydrate ) and a glycosyl acceptor. This occurs in the constant domains of antibodies such as IgG.

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
