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 following chart shows the solubility of various ionic compounds in water at 1 atm pressure and room temperature (approx. 25 °C, 298.15 K). "Soluble" means the ionic compound doesn't precipitate, while "slightly soluble" and "insoluble" mean that a solid will precipitate; "slightly soluble" compounds like calcium sulfate may require heat to precipitate.

The systematic name of this enzyme class is N-succinyl-LL-2,6-diaminoheptanedioate amidohydrolase. This enzyme is also called N-succinyl-L-alpha,epsilon-diaminopimelic acid deacylase . This enzyme participates in lysine biosynthesis .
The lysine/diaminopimelic acid branch of the aspartate pathway produces the essential amino acid lysine via the intermediate meso-diaminopimelic acid (meso-DAP), which is also a vital cell wall component in Gram-negative bacteria. [2] The production of dihydropicolinate from aspartate-semialdehyde controls flux into the lysine/diaminopimelic ...

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
