Summary Introduction
Introduction:
Proteins are complex macromolecules that are vital for the several different biological processes in the human body. Proteins are composed of amino acids, as building blocks or monomeric units. An amino acid has a carboxyl, an amino group, and an R group.

Label:
1) the type of chemical bonds between the amino acids (e.g. covalent bond, ionic bond, metallic bond)
2) the type of interparticle forces of attraction occurring within the protein and with its environment
*Indicate at least four observed interparticle forces of attraction
*pink - negatively charged, blue - positively charged, yellow - nonpolar and uncharged, green - polar and uncharged
*[See example picture] The chemical bond (shown by the arrow) is depicted as a line between the amino acids. Interparticle forces of attraction, such as the one between Phe and Glu (boxed), are not represented by lines but rather by the proximity of amino acids.
