Proteins have four levels of organization Primary Secondary Tertiary Quaternary structure structure structure structure Lys Lys Leu Ala Amino a Helix Polypeptide Assembled acids chain subunits
Proteins have four levels of organization
Levels of Organization ·Primary structure -Amino acid sequence of the protein ·Secondary structure -H bonds in the peptide chain backbone a-helix,B-sheets,B-turn,random coil ·Tertiary structure Non-covalent interactions between the R groups within the protein Quanternary structure Interaction between 2 polypeptide chains
Levels of Organization • Primary structure – Amino acid sequence of the protein • Secondary structure – H bonds in the peptide chain backbone • -helix , -sheets, -turn, random coil • Tertiary structure – Non-covalent interactions between the R groups within the protein • Quanternary structure – Interaction between 2 polypeptide chains
