four levels of protein structural organization: primary‚ secondary‚ tertiary‚ and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from long-range contacts within the chain. The quaternary structure is the organization of protein subunits‚ or two or more independent polypeptide chains. The primary structure of a protein is simply the sequence

A Brief Tutorial on Drawing Lewis Dot Structures (YouTube references at the end) Procedure for Neutral Molecules (CO2) 1. Decide how many valence (outer shell) electrons are posessed by each atom in the molecule. 2. If there is more than one atom type in the molecule‚ put the most metallic or least electronegative atom in the center. Recall that electronegativity decreases as atom moves further away from fluorine on the periodic chart. Arrangement of atoms in CO2: 3. Arrange
