Proteins are three dimensional molecules made of strands of amino acids (imagine a ball of string). There are 20 different amino
zlopas [31]

Answer:

A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.

Explanation:

Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.

Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.

When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.

Firstly, select "Administration" (section 3) because the procedure is the administration of bone marrow to the patient. Secondly, select "Circulatory" (section 30) because it is being administered in a vein (circulatory system). Third, select "Transfusion" (section 302) because it is being done a transfusion of bone marrow. Then select "Central Vein" (section 3024) because that's the place of administration in the circulatory system. Lastly, go to "Bone Marrow" (section 30240G) as that is what's being transfused and then choose "Transfusion of Allogeneic Unspecified Bone Marrow into Central Vein, Open Approach" (<span>30240G4) because it is not specified what type of transfusion it is.</span>
