Document Summary
Structure and function in proteins lecture 5. The conformation of a protein predicts its function, they are held in their shape by non-covalent bonds. Globular (polar amino acids on outside) proteins, fibrous proteins, transmembrane proteins and dna binding proteins (positively charged) are the major classifications of the different types of proteins. Primary structure is the list of amino acids in order from dna instruction. A mistake in the dna can lead to the incorrect amino acid and function problems. Secondary structure is the elements that compose the common shape within the protein. Composed of either alpha helices or beta sheets to create the folding mechanism of the protein. Tertiary structure is the shape of the protein in 3-dimentional shape (i. e globular, fibrous etc. ) Quaternary structure is comprised of multiple subunits of the tertiary structure. A telomere is when there are 2 of each subunit i. e 2 alpha helices and 2 beta sheets.
