Transcript of Informal Reading Inventory. 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.
Peptides are polymers of amino acids. A tripeptide contains three amino acid residues. Peptide bonds are ester linkages. Peptide bonds form from nucleophilic attack by an alpha-carboxyl carbon atom on an electron pair of an alpha-amino nitrogen atom of another amino acid.
