Properties of Amphiphilic and Hydrophilic Forms of AlkalinePhosphatase from Human Liver
Bibliographic record
Abstract
Amphiphilic and hydrophilic forms of alkaline phosphatase differed in electrophoretic mobility, sensitivity to heat, activation by phospholipids and albumin, and affinity of monoclonal antibodies, but were similar in substrate Km and inhibitor Ki values, sensitivity to sodium dodecyl sulfate, and electrophoretic behavior on desialylation. Chemical cross-linking experiments failed to conclusively demonstrate an aggregated state of amphiphilic alkaline phosphatase in Triton X-100. Further, attempts to identify a polymeric hybrid between amphiphilic forms of human liver and placental alkaline phosphatase were unsuccessful. We conclude that the covalent attachment of the hydrophobic phosphatidyl-inositol membrane anchor causes the amphiphilic form to behave anomalously on electrophoresis and to affect certain of the enzyme's catalytic and physical properties.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
