The digestibility and estimated glycemic indices (GI) of native (NWS), cross-linked (CLWS) and hydroxypropylated wheat starches (HPWS) were obtained by in vitro enzymatic hydrolysis. The resistant starch (RS) content and GI were found to be 6.59 and 93.13 for NWS, 7.57 and 92.20 for CLWS, and 13.15 and 89.04 for HPWS, respectively. The amounts of glucose release for CLWS were approximately 6–11...

in this research, gelatin nanoparticles were synthesized via inverse miniemulsion method by employing a mixture of a water soluble carbodiimide (cdi) and n-hydroxysuccinimide (nhs) as a non-toxic cross-linking system. the gelatin nanoparticles were characterized for their size and size distribution, morphology and stability and were compared with those of nanoparticles cross-linked by glutarald...

In higher plants the production of starch is orchestrated by chloroplast-localized biosynthetic enzymes, namely starch synthases, ADP-glucose pyrophosphorylase, and starch branching and debranching enzymes. Diurnal regulation of these enzymes, as well as starch-degrading enzymes, influences both the levels and composition of starch, and is dependent in some instances upon phosphorylation-linked...

Purpose: To analyze the physicochemical properties and in vitro digestibility of sweet potato starch phosphodiester prepared using sodium trimetaphosphate. Methods: The physicochemical properties of sweet potato starch phosphodiester were analyzed by using infrared spectrometry (IR), differential scanning calorimetry (DSC) and rapid visco-analyser (RVA). In addition, an in vitro digestibility m...

Purpose: To optimize the process conditions and analyze in vitro digestibility of corn starch phosphodiester prepared by sodium trimetaphosphate (STMP). Methods: By using response surface method, the effects of STMP concentration, pH, esterification temperature, and urea addition on digestion resistance of corn starch phosphodiester were investigated and optimal conditions were determined. Corn...

In this research, gelatin nanoparticles were synthesized via inverse miniemulsion method by employing a mixture of a water soluble carbodiimide (CDI) and N-hydroxysuccinimide (NHS) as a non-toxic cross-linking system. The gelatin nanoparticles were characterized for their size and size distribution, morphology and stability and were compared with those of nanoparticles cross-linked by glutarald...

BACKGROUND Uncooked corn-starch (UCCS) has been the mainstay of therapy for the hepatic glycogen storage diseases (GSD) but is not always effective. A new starch (WMHMS) has demonstrated a more favourable short-term metabolic profile. OBJECTIVE To determine efficacy and safety of a new uncooked starch (WMHMS) compared to UCCS over 16 weeks treatment with each. METHOD A double-blind cross-ov...

BACKGROUND Hypohidrotic ectodermal dysplasia (HED) is a severe developmental disorder in which nonallelic genetic heterogeneity has been demonstrated. Even though X-linked and autosomal recessive forms are phenotypically similar, identification of the way of transmission is mandatory to give reliable genetic counseling to the family and to address molecular studies. Complete examination of rela...

ADP-glucose pyrophosphorylase (AGP) is a heterotetrameric enzyme comprising two small and two large subunits that catalyze the production of ADP-glucose linked to starch biosynthesis. The current paradigm on leaf starch metabolism assumes that post-translational redox modification of AGP in response to light is a major determinant of fine regulation of transitory starch accumulation. According ...

s b a t c t fi BSTRACT bjective Dietary fiber represents a broad class of undiested carbohydrate components. The components vary n chemical and physical nature and in their physiological utcomes. Resistant starch is starch that escapes digesion in the small intestine and that may be fermented in he large intestine. The purpose of this study was to stimate consumption of resistant starch by the ...
