Answer:
C) substitutions that reduce the affinity of hemoglobin for oxygen
Explanation:
Heinz bodies are inclusions in the eritrocite, filled by denaturalized globin (protein part of the hemoglobin). Hemoglobin is formed by 4 globin subunits (2 alpha chains and 2 beta chains) plus a heme group. The latter, is responsible for oxygen binding.
The denaturalization of the globin is caused by substitutions that do not allow the protein to fold properly and bind the heme group accordingly. This is the cause of the Heinz bodies in the eritrocite. Therefore, this is a structural problem that impedes the protein to fold into a functional protein and has nothing to do with hemoglobin having less affinity for oxygen. In the last mentioned case, the protein is still functional but poorly binds oxygen, hence, does not for Heinz bodies.
Answer:
See explanation and image attached
Explanation:
The structure of imidazole is attached to this answer. The compound is colourless. The solid can be to dissolved in water leading an alkaline solution. Owing to the fact that imidazole possesses heteroatoms in an aromatic heterocycle it is classified as a diazole. The nitrogen atoms in imidazole are not adjacent to each other.
From the structure shown, we can see that the lone pair of the sp2 hybridized nitrogen atom is available because it is not part of the aromatic system of the heterocycle. This nitrogen is much more basic than the nitrogen atom attached to hydrogen whose lone pair becomes part of the aromatic sextet hence it unavailable for protonation and less basic.
Answer:
Vitamins are the organic molecules essential for the proper metabolism of the body. These nutrients are required in adequate amount by the body.
The following ways can be used to minimize the vitamin losses when cooking and storing food:
- Try not to remove the skin from the vegetables.
- Do not reheat the food continuously.
- Minimum amount of liquid is used in cooking.
- Always try to cook the food by steam not by boiling the food.
- A pressure cooker should be used when possible.
- Baking soda should not be used frequently to retain the color for the food.
It depends on how his body is in taking it. So he will not have to use the medication any longer. If the body is healing the body then he doesn’t have to take it anymore.
