Acid Phosphatase Activities of the Skin, Flesh, and Seed in Sechium edule , Sw, the Chayote.

The skin, flesh, and seed of the green variety of chayote ( Sechium edule ) were analyzed for relative phosphatase activities on phenyl phosphate, sodium phytate, fructose-1, 6-diphosphate, β-glycerol phosphate. glucose-1-phosphate, glucose-6-phosphate, and ATP. Relative rates of phosphatase activities were highest with ATP and lowest with glucose-1-phosphate. Activities of all phosphatases were highest in the skin and lowest in the seed.
