The Succinate - Glycine Cycle
This aminoketonic acid is the source of all the carbon atoms of protoporphyrin (2-4). In this series of reactions, t.he a-carbon atom of glycine becomes the b-carbon atom of S-aminolevulinic acid. Since the a-carbon atom of glycine, detached from its carboxyl group, is not only utilized for porphyrin synthesis but also conforms to the metabolic pattern of the “Cl” compounds (3), this carbon acy...
متن کاملCyclooctanaminium hydrogen succinate monohydrate
In the title hydrated salt, C(8)H(18)N(+)·C(4)H(5)O(4) (-)·H(2)O, the cyclo-octyl- ring of the cation is disordered over two positions in a 0.833 (3):0.167 (3) ratio. The structure contains various O-H.·O and N-H⋯O inter-actions, forming a hydrogen-bonded layer of mol-ecules perpendicular to the c axis. In each layer, the ammonium cation hydrogen bonds to two hydrogen succinate anions and one w...
متن کاملAminoguanidinium hydrogen succinate
The title compound, CH(7)N(4) (+)·C(4)H(5)O(4) (-), is a molecular salt containing discrete amino-guanidinium and succinate ions. The amino-guanidinium cation is nearly planar, with a maximum deviation of 0.035 (1) Å. The dihedral angle between the amino-guanidinium cation and the succinate anion is 3.35 (6)°. The crystal packing exhibits inter-molecular N-H⋯O and O-H⋯·O hydrogen bonds.
متن کامل3,4-Diaminopyridinium hydrogen succinate
In the title compound, C(5)H(8)N(3) (+)·C(4)H(5)O(4) (-), the pyridine N atom of the 3,4-diamino-pyridine mol-ecule is protonated. The protonated N atom participates in an N-H⋯O hydrogen bond to a succinate O atom of the singly deprotonated succinate anion. Each of the two amino groups are hydrogen-bonded to the O atoms of two different sets of succinate groups.. The crystal structure is furthe...
متن کامل4-Aminopyridinium hydrogen succinate
In the title salt, C(5)H(7)N(2) (+)·C(4)H(5)O(4) (-), the asymmetric unit comprises an amino-pyridinium cation and a hydrogen succinate anion as protonation of the aromatic N atom of the 4-amino-pyridine mol-ecule has occurred. The crystal packing is stabilized by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds that lead to a two-dimensional array. Short C-H⋯O contacts are also present.
