Dawn Talbott Definition: Informal Reading Inventory (IRI) Diagnostic assessment that is administered in a series of tests to evaluate different parts of a student's reading ability and performance. Betts regarded informal assessment a more accurate indicator of a student's reading ability.
Any reaction that combines two monomers in a reaction that generates H 2 O as one of the products is known as a dehydration reaction, so peptide bond formation is an example of a dehydration reaction.
Two amino acid molecules can be covalently joined through a substituted amide linkage, termed a peptide bond, to yield a dipeptide. Such a linkage is formed by removal of the elements of water from the Î±-carboxyl group of one amino acid and the Î±-amino group of another (Fig. 5-15).
