Inulin, a natural fructan, cannot be hydrolyzed by digestive enzymes in the human body and plays a role as a dietary fiber and prebiotic. Due to its versatile physicochemical properties and physiological functions, inulin has been widely applied in food, pharmaceuticals, and many other fields. The microorganism-derived inulin-forming enzyme inulosucrase (ISase) (
184.108.40.206) can biosynthesize higher-molecular-weight inulin than plants using sucrose as the sole substrate, and the enzyme also shows transfructosylation activity toward other saccharide acceptors. In this article, the properties, functions, and applications of inulin are overviewed. The biosynthesis of inulin by ISase is addressed, including ISase characteristics, structural features, molecular modifications and applications.

In this study, in order to directly and efficiently convert inulin into a single-cell oil (SCO), an INU1 gene encoding inulinase from Kluyveromyces marxianus was integrated into the genomic DNA and ac...
Structural analysis of molecular pores can yield important information on their behaviour in solution and in the bulk. We developed pywindow, a python package that allows for the automated analysis of...
The short chain fatty acid (SCFA) propionate, produced through fermentation of dietary fibre by the gut microbiota, has been shown to alter hepatic metabolic processes that reduce lipid storage. We ai...
The germin-like protein (GLP) purified from Thevetia peruviana, Peruvianin-I, is the only one described as having proteolytic activity. Therefore, the goal of this study was to investigate the structu...
High chemical input is required for enzymatic production of xylo-oligosaccharides (XOS) using xylan extracted from lignocellulosic biomass. In this study, enzymatic hydrolysis of alkaline oxidation (A...
This is an acute human bioavailability study in self-reported healthy participants aged 20-70 years old. We hypothesize that combination of dietary polyphenolics and non-digestible carbohy...

This is an acute human bioavailability study in self-reported healthy participants aged 20-70 years old. The investigators hypothesize that combination of polyphenolics from a soup rich in...
Halitosis associated with tongue coating results from the production of volatile sulfur compounds by bacterial action. The use of prebiotics and probiotics might be useful in treating such...
The intake of inulin products has been linked to multiple health benefits which has lead to inulin fortification in food products. The investigators hypothesis that doses of up to 10 gram...
Artifactual vesicles formed from the endoplasmic reticulum when cells are disrupted. They are isolated by differential centrifugation and are composed of three structural features: rough vesicles, smooth vesicles, and ribosomes. Numerous enzyme activities are associated with the microsomal fraction.

Those characteristics that distinguish one SEX from the other. The primary sex characteristics are the OVARIES and TESTES and their related hormones. Secondary sex characteristics are those which are masculine or feminine but not directly related to reproduction.
Procedures by which protein structure and function are changed or created in vitro by altering existing or synthesizing new structural genes that direct the synthesis of proteins with sought-after properties. Such procedures may include the design of MOLECULAR MODELS of proteins using COMPUTER GRAPHICS or other molecular modeling techniques; site-specific mutagenesis (MUTAGENESIS, SITE-SPECIFIC) of existing genes; and DIRECTED MOLECULAR EVOLUTION techniques to create new genes.
RNA which does not code for protein but has some enzymatic, structural or regulatory function. Although ribosomal RNA; (RNA, RIBOSOMAL) and transfer RNA; (RNA, TRANSFER) are also untranslated they are not included here.
A structural subclass of streptogramins that includes molecules containing unsaturated macrocyclic lactones with approximate molecular weight of 500 KDa.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
Food is any substance consumed to provide nutritional support for the body. It is usually of plant or animal origin, and contains essential nutrients, such as carbohydrates, fats, proteins, vitamins, or minerals. The substance is ingested by an organism ...
