    INTRODUCTION: LYSOZYME PART I - THE PROCESSES IN OUTLINE Organic chemistry: the atoms Strong bonds: nature, length, directional properties, rotation about bonds Weak bonds: hydrogen bonds - directional van der Walls force - non-directional Digression on molecular models Chemical formulae Why it usually doesn't fix the shape Preamble: The 3-D structure of lysozyme;its enzymatic function. The active site, specificity and çhepiical action. Protein molecules: Their chemical formulae: polypeptide chains the 20 amino acids digression on protein modification ■' The number of> possible polypeptide chains The number of different proteins in one cell. The identity of protein molecules of one type. Differences and similarities between and within species. The 3-D structure: Outline description of the fold The a-helix; the ß-sheet Irregular parts Forces holding the molecule in shape - S-S bridges - hydrogen bonds - salt bridges - hydrophobic contacts
