Elasmobranchs maintain a high concentration of NaCl in their extracellular fluid, which is matched intracellularly by organic solutes such as p-amino acids. Hypo-osmotic stress causes a volume regulatory response involving a n increased efflux of p-amino acids. The mechanism of transmembrane signali
## Abstract Neutral, organic molecules with seven or less major atoms permeate erythrocytes of the little skate (__Raja erinacea__.) Hypotonicity (80%) increased permeation up to 10โfold. Under both isotonic and hypotonic conditions solute influx occurred with the same size limitation, indicating t
The pathway of p-alanine (BALA) oxidation was examined in the liver of the little skate, Raja erinacea. BALA oxidation in liver slices was reduced by inhibitors of transamination and mitochondria1 electron transport. Experiments with liver homogenates indicated that BALA was oxidized by a twostep pr
