Summary of "Effect of enzyme de-esterified pectin on the electrostatic complexation with pea protein isolate under different mixing conditions."

Native high methoxy citrus pectin (NP) was de-esterified by pectin methyl esterase to produce modified pectins [MP (42, 37, and 33)] having different degrees of esterification. Complex coacervation between a pea protein isolate (PPI) and each pectin was investigated as a function of pH (8.0-1.5) and mixing ratio (1:1-30:1, PPI-pectin). Complex formation was found to be optimal for biopolymer-mixing ratios of 8:1, 8:1, 25:1 and 25:1 for PPI complexed with NP, MP42, MP37 and MP33, respectively, at pHs 3.6, 3.5, 3.9 and 3.9. And, the critical pHs associated with complex formation (accessed by turbidity) was found to shift significantly to higher pHs as the degree of esterification of the pectin decreased, whereas the shift in the pH corresponding to their initial interactions was minimal with degree of esterification. Complexation of PPI with NP and MP42 greatly improved the protein solubility.

Medical and Biotech [MESH] Definitions

A pharmaceutical preparation containing a mixture of esterified estrogens derived from estrogen sulfates, principally from ESTRONE sulfate. Esterified estrogen content should be 75-85% of the estrone sulfate and 6-15% of the EQUILIN sulfate.

An effect usually, but not necessarily, beneficial that is attributable to an expectation that the regimen will have an effect, i.e., the effect is due to the power of suggestion.

Chemical compounds applied to materials to reduce their retention of an electrostatic charge.

An autophagy-related protein that functions in AUTOPHAGOSOME biogenesis. It is conjugated to the ATG12 PROTEIN via a process that is similar to UBIQUITINATION and involves the ATG7 PROTEIN and ATG10 enzyme. The ATG12-ATG5 conjugate acts as an E3 UBIQUITIN LIGASE-like enzyme and is required for the localization of ATG8 PROTEINS to AUTOPHAGOSOME vesicle membranes and modification of membrane lipids.

A synthetic PGE2 analog that has an inhibitory effect on gastric acid secretion, a mucoprotective effect, and a postprandial lowering effect on gastrin. It has been shown to be efficient and safe in the treatment of gastroduodenal ulcers.
