Engineering Potato Starch with a Higher Phosphate Content
Phosphate esters are responsible for valuable and unique functionalities of starch for industrial applications. Also in the cell phosphate esters play a role in starch metabolism, which so far has not been well characterized in storage starch. Laforin, a human enzyme composed of a carbohydrate-binding module and a dual-specificity phosphatase domain, is involved in the dephosphorylation of glyc...
متن کاملLocation of Phosphate Esters in a Wheat Starch Phosphate by 3 " P - Nuclear Magnetic Resonance Spectroscopy '
Cereal Chem. 70(2):145-152 Phosphate esters of D-glucose, methyl c-D-glucopyranoside, and on potato starch were confirmed to be the 6and 3-esters. The wheat maltose, as well as the a,,y-limit phosphodextrins from native potato starch phosphate, prepared by heating starch with sodium tripolystarch (degree of substitution [DS] 0.0033) and phosphorylated amylose phosphate under semidry conditions ...
متن کاملEnhancement of Dissolution Rate and Formulation Development of Ritonavir Tablets Employing Starch Phosphate- a New Modified Starch
The objective of the study is to prepare, characterize and evaluate starch phosphate, a new modified starch as a carrier in solid dispersions for enhancing the dissolution rate of ritonavir. The feasibility of formulating solid dispersions of ritonavir in starch phosphate into compressed tablets with enhanced dissolution rate was also investigated. Starch phosphate was prepared by reacting star...
متن کاملFormulation Development of Etoricoxib Tablets by Wet Granulation and Direct Compression Methods Employing Starch Phosphate- A New Modified Starch
The objective of the present study is to develop etoricoxib rapidly dissolving tablet formulations by wet granulation and direct compression methods employing starch phosphate, a new modified starch. As per FDA guidelines on biowaivers, drug products containing weakly acidic BCS class II drugs with a dissolution of > 85% in 30 min are eligible for biowaiver. Hence a dissolution of > 85% in 30 m...
متن کاملA mutant of Arabidopsis lacking the triose-phosphate/phosphate translocator reveals metabolic regulation of starch breakdown in the light.
The chloroplast envelope triose-phosphate/phosphate translocator (TPT) is responsible for carbohydrate export during photosynthesis. Using measurements of carbohydrates, partitioning of assimilated 14CO2, photosynthetic gas exchange, and chlorophyll fluorescence, we show that a mutant of Arabidopsis lacking the TPT increases synthesis of starch compared to the wild type, thereby compensating fo...
