Answer:

-A disulfide bond joins the sulfur atoms in two adjacent polypeptide chains.

-Permanent wave solution breaks a disulfide bond by adding a hydrogen atom to each of its sulfur atoms.

-The sulfur atoms attach to the hydrogen atom from the permanent waving solution, breaking their attachment to each other.

-Once the disulfide bond is broken, the polypeptide chains can form into their new curled shape. Reduction breaks disulfide bonds and oxidation reforms them.

A Burial at Ornans

<em>Gustave Courbet</em>

This painting depicts the burial of Courbet’s great uncle in the small French town of Ornans, and it is considered to be one of the turning points in French art. The painting depicted the scene with an unflattering air, and it did not romanticize the depictions of grief and mourning, as in traditional Romantic paintings. Critics of the piece decried both the style of the painting as well as the size. At 10 feet tall by 22 feet wide, the size of the canvas was typically reserved for religious or heroic scenes, and the painting critics said was intentionally ugly and harsh. For the subjects in the painting, Courbet also used the real people who had actually been at the burial, rather than actors used as models for the art. As it had such a deleterious effect on the Romantic style of painting, it could also be easily called “The Burial of Romanticism,” as Courbet himself said: “The Burial at Ornans was in reality the burial of Romanticism.”

This 22 foot long canvas situated in a main room at the Musee d'Orsay buries the viewer as if he or she were in a cave. In a decidedly non-classical composition, figures mill about in the darkness, unfocused on ceremony. As a prime example of Realism, the painting sticks to the facts of a real burial and avoids amplified spiritual connotations. Emphasizing the temporal nature of life, Courbet intentionally did not let the light in the painting express the eternal. While sunset could have expressed the great transition of the soul from the temporal to the eternal, Courbet covered the evening sky with clouds so the passage of day into night is just a simple echo of the coffin passing from light into the dark of the ground. Some critics saw the adherence to the strict facts of death as slighting religion and criticized it as a shabbily composed structure with worn-faced working folk raised up to life-size in a gigantic work as if they had some kind of noble importance. Other critics such as Proudhon loved the inference of equality and virtue of all people and recognized how such a painting could help turn the course of Western art and politics.
