Represents the entire Microsoft Excel application. The Application object contains: Application-wide settings and options (many of the options in the Options dialog box (Tools menu), for example). Methods that return top-level objects, such as ActiveCell, ActiveSheet, and so on.
Proteins consist of one or more of these polypeptide chains. The primary structure of a protein is known as a polypeptide. From the two terminals of the polypeptide chain, N-terminus is where the amino group is free, and the c-terminus is where the carboxyl group is free. Polypeptides are synthesized at ribosomes.The amino acid sequence in the polypeptide chain is determined by the codons in mRNA. Protein. Proteins are one of the most important types of macromolecules in living organisms.he primary structure of a protein is known as a polypeptide. From the two terminals of the polypeptide chain, N-terminus is where the amino group is free, and the c-terminus is where the carboxyl group is free. Polypeptides are synthesized at ribosomes.
Proteins play important roles within our cells. Each protein is made up of at least one polypeptide chain. This lesson will discuss the synthesis of polypeptide chains and will emphasize the relationship between its structure and function.ach polypeptide chain is a series of amino acids joined together in a specific sequence. Because each amino acid has a unique R group, a particular amino acid sequence creates a polypeptide whose function is dependent upon its chemical structure.
