Although ESI-MS analyses identified HNP-1 (3.442 Da), lysozyme (14.692 Da), and psoriasin (11.366 Da), the unknown antimicrobial compound did not show any signal > 1.000 Da. A representative chromatogram, which shows the highest amounts of the unknown antibiotic, is shown. This peak was ...
(Li) and oxygen combine to create lithium oxide (Li2O). Sometimes, a new compound might form when an element is exposed to an existing compound. For example, when pure elemental sodium (Na) is submerged into liquid water (H2O), a reaction occurs, resulting in the formation of sodium ...
