Question

Review| Constants| Periodic Table Protein structure is conceptually divided into four levels, from most basic to higher order Primary structure describes the order of amino acids in the peptide chain. Secondary structure describes the basic three-dimensional structures, a-helices and B sheets. Tertiary structure describes how the secondary structures come together to form an individual globular protein. Quatemary structure results from individual proteins coming together to form multi-subunit protein complexes Part A Complete the following vocabulary exercise relating to the level of structure in proteins Match the words in the left-hand column with the appropriate blank in the sentences in the right-hand column View Available Hint s) Reset Help Primary structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding between backbone atoms located near each other in the polypeptide chain Tertiary strueture is the result of two or more protein subunits assembling to form a larger Quatemary biologically active protein complex structure is achieved when a pratein folds into a compact, three-dimensional shape stabilized by interactions between side-chain R groups of amino acids structure is the sequence of amino acids in a protein Submit
