The mechanism of action of probiotics (e.g., having an impact on the intestinal microbiota or enhancing immune function) was dropped from the definition to encompass health effects due to novel mechanisms and to allow application of the term before the mechanism is confirmed.
Noun. 1. electronegativity - (chemistry) the tendency of an atom or radical to attract electrons in the formation of an ionic bond. negativity.
Electronegativity is a quadratic function of partial charge given by the following equation. Where q is the partial charge on the atom a,b, and c are coefficients determined from I v and E v Orbital electronegativity, and subsequently partial charge distribution of any molecule is calculated iteratively. 3. Examples of Charge Calculation Example 1.
