Disulfide bonds result in a part, of the three dimensional shape of the molecule, not in the order of the amino acids. The peptide chain twists back and forth, with the side chanis pointed outward. 20.40 See page 581. You should be very familiar with the material on this page and on page 582. 20.47 Denaturation affects the tertiary structure of the protein.
Digestion breaks peptide bonds and affects the primary structure of the protein.
A very important difference. The problems assigned on the syllabus are very representative of what you should be concentrating on in this chapter. To do this you must understand the basic structures of lipids and phospholipids and of course must know the structure of glycerol and phosphate. Answers to the the assigned problems not given in the text are given here. Any decomposed plant or animal matter, which can be extracted with a nonpolar solvent is classified as a lipid.
