[A model of tissue thromboplastin]

The molecular structure of the human brain tissue thromboplastin was studied by the method of NMR-31P and 1H using the shifting reagent. Molecular model of the tissue thromboplastin is suggested. According to the model only 10-20% of polar phosphate-containing heads are exposed outside. Phospholipids located deeper form hexagonal (HII) cylinders which may consist only of lipids or of complexes with proteins.
