Answer: protein structure

Explanation:

In Sickle-cell anemia, the gene sequence of hemoglobin is changed in its sixth position due to the substitution of glutamate with valine.

So, since glutamate, an amino acid soluble in water due to its hydrophilic side chain is substituted with valine, an amino acid that has a hydrophobic side chain insoluble in water or bloodstream; the resulting hemoglobin protein is altered in structure (sickle shaped) and unable to bind and transport oxygen efficiently to the various body parts.
