Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream. Digestion is a form of catabolism that is often divided into two processes based on how food is broken down: mechanical and chemical digestion. The term mechanical digestion refers to the physical breakdown of large pieces of food into smaller pieces which can subsequently be accessed by digestive enzymes. In chemical digestion, enzymes break down food into the small molecules the body can use.

Systematic evolution of ligands by exponential enrichment: photoselection of nucleic acid ligands and solution selex

A method for identifying nucleic acid ligands to target molecules using the SELEX procedure wherein the candidate nucleic acids contain photoreactive groups and nucleic acid ligands identified thereby are claimed. The complexes of increased affinity nucleic acids and target molecules formed in the procedure are crosslinked by irradiation to facilitate separation from unbound nucleic acids. In other methods partitioning of high and low affinity nucleic acids is facilitated by primer extension steps as shown in the figure in which chain termination nucleotides, digestion resistant nucleotides or nucleotides that allow retention of the cDNA product on an affinity matrix are differentially incorporated into the cDNA products of either the high or low affinity nucleic acids and the cDNA products are treated accordingly to amplification, enzymatic or chemical digestion or by contact with an affinity matrix.

Method and system for rapid biomolecular recognition of amino acids and protein sequencing

Methods, compositions, kits, and apparatus are provided wherein the aminoacyl-tRNA synthetase system is used to analyze amino acids. The method allows very small devices for quantitative or semi-quantitative analysis of the amino acids in samples or in sequential or complete proteolytic digestions. The methods can be readily applied to the detection and / or quantitation of one or more primary amino acids by using cognate aminoacyl-tRNA synthetase and cognate tRNA. The basis of the method is that each of the 20 synthetases and / or a tRNA specific for a different amino acid is separated spatially or differentially labeled. The reactions catalyzed by all 20 synthetases may be monitored simultaneously, or nearly simultaneously, or in parallel. Each separately positioned synthetase or tRNA will signal its cognate amino acid. The synthetase reactions can be monitored using continuous spectroscopic assays. Alternatively, since elongation factor Tu:GTP (EF-Tu:GTP) specifically binds all AA-tRNAs, the aminoacylation reactions catalyzed by the synthetases can be monitored using ligand assays. Microarrays and microsensors for amino acid analysis are provided. Additionally, amino acid analysis devices are integrated with protease digestions to produce miniaturized enzymatic sequenators capable of generating either N- or C-terminal sequence and composition data for a protein or peptide. The possibility of parallel processing of many samples in an automated manner is discussed.

Reduced digestible carbohydrate food having reduced blood glucose response

Reducing the digestion of digestible carbohydrates in a digestible carbohydrate-based material, and reducing the absorption of the digestion product(s) of digestible carbohydrates (that is, simple sugars) within the small intestine. The undigested digestible carbohydrate and the unabsorbed digestion products pass through the small intestines and into the colon, where they are fermented. In effect, the food materials made by practicing the present invention cause a controlled amount of digestible carbohydrate to by-pass the small intestine, resulting in the fermentation of digestible carbohydrates in the colon. The invention also provides for processing of a digestible carbohydrate-based ingredient with a non-digestible food film material, to form a reduced digestible carbohydrate food having a protective food film network, which can inhibit or prevent digestion of the digestible carbohydrate. The present invention also provides for processing of a digestible carbohydrate-based ingredient with a non-digestible food film material, to provide a resulting reduced digestible carbohydrate food containing a viscosity-building component that contributes to the formation of a viscous intestinal chyme that can inhibit or prevent digestion of the digestible carbohydrate and can inhibit adsorption of digestion products of digestible carbohydrates in the small intestine.

Production of biodiesel and other valuable chemicals from wastewater treatment plant sludges

A process for producing biodiesel has been invented by first extracting lipids from the sludges generated during primary and / or biological treatment of municipal, agricultural, and industrial wastewaters using primary, secondary, and tertiary treatments followed by the transesterification of the extracted lipids using transesterification conversion into alcohol-based esters. The resulting products from this process include biodiesel, glycerol, lipid-free proteins, various other useful chemicals and an aqueous-based substrate well suited for optimized digestion within subsequent biological digestion (either aerobic or anaerobic). The lipids extracted from the sludges containing high levels of microorganisms are phospholipids which can also be directly used as lecithin. The extraction of the lipids from the sludges will be performed using chemical extraction techniques with the transesterification of the extracted lipids accomplished using basic, acidic, and / or a combination of the two transesterification techniques.
