Ionic Bonds, Polar Covalent Bonds, and Nonpolar Covalent Bonds
This organic chemistry video tutorial explains how to identify a bond as an ionic bond, polar covalent bond, or a nonpolar covalent bond. Ionic bonds usually consist of metals and nonmetals where as covalent bonds consists of nonmetals. In a nonpolar covalent bond, electrons are shared equally and the electronegativity difference between the two atoms is 0.4 or less. For polar covalent bonds, the electrons are shared unequally between the two atoms and the electronegativity difference is defined to be 0.5 or more

Protein Structure - Primary, Secondary, Tertiary, & Quarternary - Biology
This biology video tutorial provides a basic introduction into the four levels of protein structure - primary, secondary, tertiary and quarternary structure. The primary structure of a protein is based on the sequence of amino acids. The secondary structure is based on localized shapes such as the alpha helix or the beta pleated sheet. The tertiary structure of a protein describes its three-dimensional folding pattern. A tertiary structure contains one individual subunit where as a quarternary structure has multiple subunits
