Towards (attribute)
This attribute is used to specify the third element of a relational quality, the first two elements being the type of property and the entity in which the quality inheres. The type of property is typically a concentration, and the entity in which it inheres is typically a fluid such as plasma, serum or blood. The third element typically is the substance or molecule that is the thing being measured as a concentration. The concentration of sodium in blood would be "property type" concentration, "towards" sodium, "inheres in" blood.
