INORGANIC PHOSPHATE [6 records]

Record 1 2021-10-04

English

Subject field(s)
  • Aquaculture
DEF

A procedure in which the water is completely drained from the pond to improve the fertility by enabling air to penetrate the sediments and by assisting in the breakdown and mineralization of organic matter [that] produces inorganic nutrients(nitrate, phosphate, carbonate).

PHR

pond dry-out

French

Domaine(s)
  • Aquaculture
DEF

Méthode consistant à vider l'étang, afin de minéraliser les matières organiques, de supprimer certains bioagresseurs et de contrôler la végétation qui améliore la production primaire.

CONT

phosphate group : Oxygenated phosphorus attached to a carbon chain(called inorganic phosphate when not attached.

CONT

The ATP molecule consists of a nitrogen-containing organic base(adenine), a sugar(ribose) and a string of three phosphate groups.... In most of the reactions where ATP serves as an energy currency only the terminal phosphate group is involved. ATP is formed by attaching a third phosphate to adenosine diphosphate(ADP) with the elimination of water. The reaction does not proceed spontaneously; on the contrary, a substantial quantity of energy must be supplied. Much of that energy can then be recovered in the reverse reaction, in which ATP is split into ADP and inorganic phosphate.

CONT

Most of the usable energy in the body comes from splitting the energy rich molecule adenosine triphosphate(ATP) into the lower-energy products adenosine diphosphate(ADP) and inorganic phosphate(Pi).

  • Biochimie
CONT

La molécule d'ATP comprend une base organique qui contient un groupe azoté (l'adénine), un sucre (le ribose) et une série de trois groupements phosphate [...] La plupart des réactions où l'ATP fournit l'énergie ne font intervenir que le phosphate terminal. L'ATP se forme par addition d'un troisième phosphate à l'adénosine-diphosphate (ADP) et élimination d'une molécule d'eau. La réaction ne s'effectue pas spontanément; elle nécessite au contraire l'apport d'une quantité importante d'énergie dont la majeure partie peut ensuite être récupérée au cours de la réaction inverse dans laquelle l'ATP est scindé en ADP et en phosphate inorganique.

CONT

La plus grande partie de l'énergie utilisable par l'organisme provient de la dégradation d'une molécule réservoir d'énergie, l'ATP (adénosine-triphosphate) en ADP (adénosine diphosphate), moins riche en énergie, et en phosphate inorganique (Pi).

Record 3 2011-01-10

English

Subject field(s)
  • Biological Sciences
DEF

Transfer of the carbamoyl of carbamoyl phosphate to an amino group with elimination of inorganic phosphate.

OBS

Many polymers containing isocyanate or isothiocyanate functional groups have been used as carbamylating or thiocarbamylating reagents, respectively, to effect coupling of proteins illustrating a class of immobilization technique. Polymers containing the isothiocyanate group have gained larger acceptance than those containing isocyanate owing to the higher stability of the former and the relative ease of its preparation. When isocyanates react in aqueous medium with proteins, the isocyanato groups are mainly hydrolyzed.

Le traitement d'érythrocytes drépanocytaires par l'isocyanate provoque une carbamoylation des groupements aminés libres des valines N-terminales de l'hémoglobine S.

Subject field(s)
  • Translation (General)
  • Industrial Crops
CONT

... potato production is usually low because of imbalanced use of inorganic fertilizers and low input of organic manure. Over-applying nitrogen(N) also resulted in low quality, which is characterized by vulnerability to rot, higher water content in tubers, and lower commercial value. Therefore, there is a need to improve potato yield and quality through balanced use of N, phosphate(P), and potash(K).

Record 5 2003-11-18

English

Subject field(s)
  • Biological Sciences
DEF

General term for an enzyme transferring an inorganic phosphate group to some organic acceptor, hence belonging to the transferases.

CONT

Some enzymes may exist in two forms of different activity which are interconvertible. Frequently, the mechanism of interconversion consists of phosphorylation .... One of the best known cases is glycogen phosphorylase, the enzyme that degrades glycogen into its glucose units, and which exists in two forms: a and b. Phosphorylase a is a tetrameric protein having the higher activity; phosphorylase b is a less active dimer. The b form can be converted into the a form by the convalent binding of four phosphate groups.

French

Domaine(s)
  • Sciences biologiques
DEF

Toute enzyme qui catalyse la phosphorolyse d'un composé par l'acide phosphorique.

CONT

Le glycogène est dégradé par phosphorolyse. Ceci signifie que le glycogène subit des coupures au niveau des restes de glucose, non pas hydrolytiques (avec fixation d'une molécule d'eau), mais phosphorolytiques (fixation d'une molécule d'acide phosphorique). Cette réaction est catalysée par une enzyme, la phosphorylase, enzyme très complexe (Cori, Sutherland) qui a été préparée à partir du foie et du muscle. Les enzymes des deux origines sont d'ailleurs de structure très différente.
