alkaline [al´kah-līn]

1. having the reactions of an alkali.

2. having a pH greater than 7.0.

alkaline phosphatase an enzyme localized on cell membranes that hydrolyzes phosphate esters liberating inorganic phosphate and has an optimal pH of about 10.0. Serum alkaline phosphatase activity is elevated in hepatobiliary disease, especially in obstructive jaundice, and in bone diseases with increased osteoblastic activity such as hyperparathyroidism, osteitis deformans, and bone cancer. The liver and bone tissue each produce a distinct isoenzyme.

alkaline phosphatase

a nonspecific enzyme localized on cell membranes that hydrolyzes phosphate esters liberating inorganic phosphate and has an optimal pH of about 9.5. Serum alkaline phosphatase activity is elevated in hepatobiliary disease, especially in obstructive jaundice, and in bone diseases with increased osteoblastic activity such as hyperparathyroidism, osteitis deformans and bone cancer. The liver and bone tissue each produce a distinct isoenzyme. Called also AP, alkaline phosphomonoesterase, glycerophosphatase.

alkaline picrate test

a technique for estimating urine creatinine levels.

alkaline tide

see postprandial alkaline tide.

alkaline urine

the urine of carnivores is acidic, that of herbivores is alkaline. The presence of an alkaline urine in a carnivore, provided the sample is fresh and uncontaminated, is an indication that the patient is alkalotic, but urine findings must always be interpreted with caution.
