The importance of phosphates in the metabolism of plants and animals

Bring fact-checked results to the top of your browser search. The study of metabolic pathways There are two main reasons for studying a metabolic pathway: Studies with whole organisms or organs can provide information that one substance is converted to another and that this process is localized in a certain tissue ; for example, experiments can show that ureathe chief nitrogen-containing end product of protein metabolism in mammalsis formed exclusively in the liver. They cannot reveal, however, the details of the enzymatic steps involved.

Its synthesis in plants is a two-step process, involving the production of trehalosephosphate T6P catalyzed by trehalosephosphate synthase TPS and its consecutive dephosphorylation to trehalose, catalyzed by trehalosephosphate phosphatase TPP.

T6P has recently emerged as an important signaling metabolite, regulating carbon assimilation and sugar status in plants. In addition, T6P has also been demonstrated to play an essential role in plant development. This review recapitulates the recent advances we have made in understanding the role of T6P in coordinating diverse metabolic and developmental processes.

These complex carbohydrates fulfill very diverse functions in plants and are, for example, used as long-term energy storage or constitute important structural components of plant cells. In addition to their metabolic and structural roles, carbohydrates can also influence plant growth and development by acting as elicitors or growth regulators Creelman and Mullet, The regulation of plant development by carbohydrates has attracted a lot of interest over the last few years and several signaling pathways that integrate sugar responses have been identified.

One such pathway involves the synthesis, perception, and response to the non-reducing disaccharide trehalose and its precursor trehalosephosphate T6P.

Trehalose is widely distributed in actinomycetes, fungi, insects, and other invertebrates Veluthambi et al. However, the majority of land plants contain only low quantities of trehalose, making its role in stress protection seem unlikely Zentella et al.

The biosynthesis of trehalose in plants involves the generation of trehalosephosphate T6P from glucosephosphate and UDP-glucose by trehalosephosphate synthase TPSand the subsequent dephosphorylation of T6P to trehalose by trehalosephosphate phosphatase TPP; Cabib and Leloir, Table 1 Genes involved in trehalose metabolism in Arabidopsis thaliana.The importance of organic phosphates in metabolism was first indi­cated by the studies of Harden and Young, who found that fermentation of glucose by cell-free yeast juice in­creased rapidly when inorganic phosphorus is added to the medium, which was later converted to organical­ly bound phosphate.

Phosphorus is an important constituent in every body tissue.

The total amount constitutes about one per cent of the body weight. The amount of phosphorus in the body is exceeded only by calcium. In bones the proportion of calcium to phosphorus is much higher than that of calcium.

Trehalose, a sugar found in many species of plants and animals, is a non-reducing disaccharide composed of two glucose moieties. Phosphorus (P) is one of the most important elements for plant growth and metabolism.

It plays key roles in many plant processes such as energy metabolism, the synthesis of nucleic acids and membranes, photosynthesis, respiration, nitrogen fixation and enzyme regulation (Raghothama, ).
