dHB

DHB is an acronym with multiple meanings across different fields. Two widely recognized uses are the Deutscher Handballbund (DHB), the German Handball Federation, and 2,5-dihydroxybenzoic acid, a chemical compound used as a matrix in MALDI mass spectrometry. Context is important to determine which meaning is intended.

Deutscher Handballbund is the national governing body for the sport of handball in Germany. It oversees the organization of the national teams, development programs, and the governance of the sport at the national level. The DHB represents German handball in international bodies and assists in coaching, refereeing standards, and competition administration. It is involved in promoting the sport from grassroots to elite levels within Germany and works with regional associations to coordinate activities.

2,5-Dihydroxybenzoic acid, also known as gentisic acid, is a chemical compound used prominently as a matrix in MALDI (matrix-assisted laser desorption/ionization) mass spectrometry. As a matrix, it facilitates the desorption and ionization of biomolecules such as peptides and proteins, as well as small molecules, enabling their analysis by mass spectrometry. DHB matrices are typically prepared in organic solvents and applied to samples to form crystalline layers that aid ionization in MALDI workflows. It is one of several matrices used in proteomics and analytical chemistry.

In summary, DHB most often refers to either the German Handball Federation or the MALDI matrix 2,5-dihydroxybenzoic acid, with the intended meaning depending on the disciplinary context.
