Document Summary
Amino acids and proteins: amino acids are the building blocks of proteins. They are formed via a condensation reaction between two amino acids which results in the formation of a peptide bond: shorter amino acid chains are referred to as polypeptides. Disulfide bonds can cross link two polypeptide chains and are critical in proper chain folding: tertiary structure determines the biological function of the protein. Quaternary function: only proteins with more than one polypeptide chain have a quaternary structure. Interactions among these chains determine the quaternary structure: folding protein -> gives the protein its biological function, misfolding protein -> causes the protein to become inactive and lose its biological function. However, starch has alpha glycosidic bonds that are easy to break but cellulose has beta ones that are hard to break. M-rna is released and is ready to go to the ribosomes.
