Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH 4) 2 (HPO 4)) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation: [2]
A dopamine reuptake inhibitor (DRI) is a class of drug which acts as a reuptake inhibitor of the monoamine neurotransmitter dopamine by blocking the action of the dopamine transporter (DAT). Reuptake inhibition is achieved when extracellular dopamine not absorbed by the postsynaptic neuron is blocked from re-entering the presynaptic neuron.
DaT Scan (DaT scan or Dopamine Transporter Scan) commonly refers to a diagnostic method, based on SPECT imaging, to investigate if there is a loss of dopaminergic neurons in striatum. The term may also refer to a brand name of Ioflupane (123I) tracer used for the study.

In the case of DAT two Na + and one Cl − ion are transported along with one DA. When ionic gradients are altered (extracellular K + increases or extracellular Na + or Cl − decreases) transporters can function in reverse resulting in a net efflux of substrates and ions out of a neuron.
Diamidophosphate (DAP) is the simplest phosphorodiamidate ion, with formula PO 2 (NH 2) 2 −. It is a phosphorylating ion and was first used for the phosphorylation of sugars in aqueous medium. [1] DAP has attracted interest in the area of primordial chemistry. [2]
Diaminopimelic acid (DAP) is an amino acid, representing an epsilon-carboxy derivative of lysine. meso-α,ε-Diaminopimelic acid is the last intermediate in the biosynthesis of lysine and undergoes decarboxylation by diaminopimelate decarboxylase to give the final product. [1] DAP is a characteristic of certain cell walls [2] of some
The Draw-a-Person test (DAP, DAP test), Draw-A-Man test (DAM), or Goodenough–Harris Draw-a-Person test is a type of test in the domain of psychology. It is both a personality test, specifically projective test, and a cognitive test like IQ. The test subject uses simple art supplies to produce depictions of people.
