Key result
Lipid class composition did not differ between low and high potassium sheep red blood cells, indicating major lipid distribution is not directly responsible for cation concentration differences.

Does not implicate lipid classes in erythrocyte cation differences; leaves open non-lipid membrane factors for further study.
Gary J. Nelson (1967) studied Sheep red blood cells (low vs high potassium) (n=10). Low potassium (LK) red cells vs. High potassium (HK) red cells was evaluated on Lipid class composition. Lipid class composition did not differ between low and high potassium sheep red blood cells, indicating major lipid distribution is not directly responsible for cation concentration differences.
