Sickle cell anemia results from a mutation in a gene called HBB, which contains the blueprint for cells to make part of a protein called hemoglobin. The hemoglobin protein is made up of two alpha chains and two beta chains.
Sickle cell anemia is the result of a point mutation, a change in just one nucleotide in the gene for hemoglobin. This mutation causes the hemoglobin in red blood cells to distort to a sickle shape when deoxygenated. The sickle-shaped blood cells clog in the capillaries, cutting off circulation.

So, we can say that in the absence of gravity, the rock and debris would never accrete into a planet.
Those would be enzymes I believe. They are the power house of the membrane and lower the amount of activation energy needed.
