Definitions: Contract; Agreement; Contract for sale; Sale; Present sale; Conforming to Contract; Termination; Cancellation. (1) In this Article unless the context otherwise requires contract and agreement are limited to those relating to the present or future sale of goods. Contract for sale includes both a present sale of goods and a contract to sell goods at a future time. A sale consists in the passing of title from the seller to the buyer for a price (Section 2-401). A present sale means a sale which is accomplished by the making of the contract. (2) Goods or conduct including any part of a performance are conforming or conform to the contract when they are in accordance with the obligations under the contract.
A single polymer molecule may consist of hundreds to a million monomers and may have a linear, branched, or network structure. Covalent bonds hold the atoms in the polymer molecules together and secondary bonds then hold groups of polymer chains together to form the polymeric material. Copolymers are polymers composed of two or more different types of monomers.
Best Answer: Proteins are linear polymers formed by linking the a-carboxyl group of one amino acid to the a-amino group of another amino acid with a peptide bond (also called an amide bond). The formation of a dipeptide from two amino acids is accompanied by the loss of a water molecule (Figure 3.18). 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).
