“…The results indicate that the lower the pH, the higher the liquid protein that is obtained. The variation of solubility of protein reveals that the interaction between dihydrogen phosphate ion and amino acids group facilitated by hydrogen bonding force to form an ion protein phosphate that is more soluble in water at pH 7 [29][30][31]. The product of the reaction between the ion dihydrogen phosphate and amino acid is shown in Fig.…”

Chemical phosphorylation of hydrolysate resulting from hydrothermal carbonization of chicken feather waste was performed to enhance the amino acids and reduce the metal ions content. The aim of this research is to improve the functional properties of chicken feathers hydrolysate without impairing the nutritional availability thereof with the cheapest chemical method by phosphorylation. Phosphorylated hydrolysate can function as animal feed and fertilizer. The hydrolysate of chicken feathers was obtained by hydrothermal carbonization in an alkaline condition using a CaO and KOH catalyst, by the ratio of water:dry matter of chicken feathers is 5:1, at 9–10 atm pressure, and in a temperature of 190–200 °C during 3 h. Phosphorylation has been carried out by reacting the hydrolysate with H3PO4 85% in pH of 5, 6, 7 and using the original hydrolysate as control. The sample that has been prepared was characterized and semi-quantitative analyzed by HPLC and AAS. The phosphorylation results showed that the total maximum protein of soluble protein, their minimum metal ions, and anion in soluble protein was obtained at pH 7, while the higher the pH, the lower the liquid protein that was obtained.

“…In biocomplexes, non-covalent bonds within coordinative systems are also very important [ 57 ]. Due to the acid-base equilibrium, phosphate groups as ligands donate protons and non-covalent complexes can form [ 38 ]. Positive centre of such interaction could be the amino group of phosphoserine itself [ 58 ].…”

“…Positive centre of such interaction could be the amino group of phosphoserine itself [ 58 ]. Jastrzab et al [ 38 ] observed the strongest non-covalent bonds in a system of phosphoserine and biogenic amines pH-dependent at a value close to 7.0, at which the phosphate group, as well as the carboxyl group, were deprotonated, whereas the amino group was still present in a protonated state. Composition (2) and composition (3) in particular set neutrally near a pH of 7 (see Fig.…”

“…The aim of this work was to investigate new mineral-organic bone cements based on phosphoserine and magnesium phosphates or magnesium oxides. These are thought to possess strong adhesive properties since Mg 2+ in biocomplexes demonstrate a strong complexation to the phosphate group of phosphorylated amino acids which, depending on the pH, partly does not complex at all [ 38 ]. Suitable formulations were identified, which were analyzed by X-ray diffraction, Fourier infrared spectroscopy and electron microscopy and subjected to mechanical tests.…”

Present surgical situations require a bone adhesive which has not yet been developed for use in clinical applications. Recently, phosphoserine modified cements (PMC) based on mixtures of o-phosphoserine (OPLS) and calcium phosphates, such as tetracalcium phosphate (TTCP) or α-tricalcium phosphate (α-TCP) as well as chelate setting magnesium phosphate cements have gained increasing popularity for their use as mineral bone adhesives. Here, we investigated new mineral-organic bone cements based on phosphoserine and magnesium phosphates or oxides, which possess excellent adhesive properties. These were analyzed by X-ray diffraction, Fourier infrared spectroscopy and electron microscopy and subjected to mechanical tests to determine the bond strength to bone after ageing at physiological conditions. The novel biomineral adhesives demonstrate excellent bond strength to bone with approximately 6.6–7.3 MPa under shear load. The adhesives are also promising due to their cohesive failure pattern and ductile character. In this context, the new adhesive cements are superior to currently prevailing bone adhesives. Future efforts on bone adhesives made from phosphoserine and Mg2+ appear to be very worthwhile. Graphical Abstract

“…Phytic acid (PA), chitosan, tannin, and so on have been used to develop bio‐derived flame retardants 19,20 . Among these bio‐derived raw materials, PA, which is an organic phosphate compound extracted from plant seeds, has attracted much attention due to the relatively high phosphorus content in its molecule 21–24 . By neutralizing PA with melamine, Wang et al prepared a bio‐derived flame retardant, organic‐inorganic hybrid (PAMA), with a unique nanolayer structure, which can be applied in EP.…”

The synthesis and application of the bio‐derived flame retardant can meet the current requirements for the high‐efficient and sustainable development of flame retardants. Therefore, using phytic acid (PA), 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO), and piperazine as raw materials, a PA‐derived flame retardant (PAPDOPO) was prepared. Fourier transform infrared spectroscopy and x‐ray diffraction techniques were applied to characterize the structure of the PAPDOPO. In the prepared flame‐retardant epoxy resin (FEP), PAPDOPO showed high flame retardancy. When 4% PAPDOPO was added into epoxy resin (EP), the prepared FEP (EP‐PAPD‐4) passed the V‐0 level in the UL‐94 test, and the limited oxygen index value of EP‐PAPD‐4 reached 35.3%. Microcombustion calorimetry test was also applied to demonstrate the performance of PAPDOPO. The peak heat release rate of EP‐PAPD‐4 was reduced by 30.4% compared with that of the pure EP. Due to the low addition amount of PAPDOPO in FEP, the mechanical properties of the FEP using PAPDOPO as flame retardant were hardly decreased compared with pure EP.
