Answer:
Iron deficiency anemia.
Explanation:
The presence of blood in her stool does not affect blood volume, but leads to iron deficiency anemia when iron stores are depleted.
Iron deficiency anemia is a common type of anemia, a condition in which the blood does not have enough healthy red blood cells. It is due to a lack of iron, so the body cannot produce a sufficient amount of hemoglobin, a substance present in red blood cells that allows them to transport oxygen. As a consequence, iron deficiency anemia can make you feel tired and short of breath.
Answer:
The correct answer to the question: What would happen if the urea were removed after oxidation, would be, C: Disulfide bonds are not positioned correctly unless weak bonding interactions are present.
Explanation:
Christian Anfinsen´s and colleagues´s research on proteins, their structure, their function, and what affects them, yielded information that has impacted the way that proteins are studied today. This research was not only able to find the structure of proteins, but also how this structure was formed, and what would happen if it was affected by different factors, meaning, if the protein would remain functional or not. In his experiment with urea, Anfinsen and his colleagues found that what mattered in protein structure was the fine balance in the elements, called residue, inside the structure, and not those on the outside. They also found that when urea was removed from the protein after oxidation had happened, then the cysteine residue would not be placed correctly inside the structure, thus affecting it and reducing its capacity to perform.
