There are three scholarships for pre-medical students that are available for the academic year. These are: Whatcom County Medical Society Scholarship: one $500 award Dr. Ralph & Mrs. Eleanor Rinne Pre-Medical Scholarship: two $1500 awards If you would like to apply, please visit for a statement of eligibility and for application details. Or, you may stop by Old Main 380 or Old Main 280 to pick up an application. Completed applications are due in Old Main 380 (Academic Advising Center) by Monday, May 3, 2010.

Other Properties of Amino Acids Stereochemistry (all biosynthetic proteins made up of L-isomer) Hydropathy (partitioning between polar and nonpolar solvents as indicator of polarity) (see Table 6-2 in VVP p 150) these two properties are major determinants of peptide conformation

Globular Protein 3 o Structure 2 o structural elements (helices, sheets, turns…) pack together to give a folded protein or subunit. This so-called “tertiary” structure is stabilized by non- covalent interactions, the hydrophobic effect and disulfides. Within the 3 o structure are “motifs” and “domains”. The 3 o structure can be derived from one or more domains.

H-bond Fun Fact 1984 survey of protein crystal data shows that “almost all groups capable of forming H-bonds do so.” (mainchain amides, polar sidechains)
