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.
The resulting CO-NH bond is called a peptide bond, and the resulting molecule is an amide. The four-atom functional group-C(=O)NH-is called an amide group or (in the context of proteins) a peptide group. Polypeptides and proteins are chains of amino acids held together by peptide bonds, as is the backbone of PNA. peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O).
