Cholesky decomposition In linear algebra, the Cholesky decomposition or Cholesky factorization is a decomposition of a Hermitian, positive-definite matrix into the product of a lower triangular matrix and its conjugate transpose, which is useful e.g. for efficient numerical solutions and Monte Carlo simulations.hen A has real entries, L has real entries as well and the factorization may be written A = LLT. The Cholesky decomposition is unique when A is positive definite; there is only one lower triangular matrix L with strictly positive diagonal entries such that A = LL *.

Is Sesame Oil Healthy Sesame oil offers a variety of health benefits as well as a nice flavor boost to your recipes. Sesame oil has been used for centuries in Asian cuisine. It has also been commonly used for medicinal purposes, especially in Ayurvedic medicine. It has a subtle nutty flavor and is used both as a cooking oil and condiment. Sesame oil is made from toasted and untoasted sesame seeds, with the oil from toasted seeds possessing a stronger sesame flavor. Sesame oil also has many health benefits that make it a good alternative oil to use in moderation.

Cholesterol Since cholesterol is essential for all animal life, each cell synthesizes it through a complex process beginning with mevalonate pathway and ending with the 19 step conversion of lanosterol to cholesterol.holesterol is oxidized by the liver into a variety of bile acids. These, in turn, are conjugated with glycine, taurine, glucuronic acid, or sulfate. A mixture of conjugated and nonconjugated bile acids, along with cholesterol itself, is excreted from the liver into the bile.

- Catechol oxidase is an enzyme that catalyses the oxidation of phenols such as catechol. Catechol oxidase is a copper-containing enzyme whose activity is similar to that of tyrosinase, a related class of copper oxidases.atechol oxidase carries out the oxidation of phenols such as catechol, using dioxygen (O 2). In the presence of catechol, benzoquinone is formed (see reaction below). Hydrogens removed from catechol combine with oxygen to form water.

Fischer-Tropsch process The Fischer–Tropsch process is a set of chemical reactions that changes a mixture of carbon monoxide gas and hydrogen gas into liquid hydrocarbons. People care about the F-T process for many different reasons, for example, it might be a way to make fuel for cars and trucks that doesn't pollute as much as fossil fuels.

elliesfoodblog Cooking with chemistry: gelatinisation. In class today we studied the shape and structure of three different starch granules, corn flour, wheat flour and potato starch. In addition we looked at the usefulness of gelatinization in cooking by making a risotto, and a white sauce.STRUCTURE OF STARCH GRANULES. Gelatinization is the process in which starch thickens by absorbing liquid in the presence of heat. The heat breaks down the starch molecules allowing it to absorb the liquid.When the starch is heated to roughly 60 degrees, it starts to absorb liquid.elatinisation is used in food preparation as an adhesive and a thickening agent for foods. Gelatinisation of starch is used for meals like risotto, and for sauces like gravy my favourite to use with any type of roast! and white sauces used as a part of a dish like lasagne.

Cholecystectomy Cholecystectomy (/ˌkɒləsɪsˈtɛktəmi/ ; plural: cholecystectomies) is the surgical removal of the gallbladder.It is a common treatment of symptomatic gallstones and other gallbladder conditions.ndications for cholecystectomy include inflammation of the gall bladder (cholecystitis), biliary colic, risk factors for gall bladder cancer, and pancreatitis caused by gall stones.

LCAT gene The LCAT enzyme helps transport cholesterol out of the blood and tissues by a process called cholesterol esterification. This process results in a form of cholesterol that is more efficiently carried by molecules called lipoproteins, which transport the cholesterol to the liver.

XSL Transformations (XSLT) XSL Transformations (XSLT) is a standard way to describe how to transform (change) the structure of an XML (Extensible Markup Language) document into an XML document with a different structure.XSLT is a Recommendation of the World Wide Web Consortium (W3C).SL is a language for formatting an XML document (for example, showing how the data described in the XML document should be presented in a Web page). XSLT shows how the XML document should be reorganized into another data structure (which could then be presented by following an XSL style sheet).

- By converting cholesterol to cholesteryl esters more cholesterol can be packaged into the interior of lipoproteins. This vastly increases the capacity of lipoproteins, allowing for more efficient cholesterol transport through the blood stream.

Cholesterol In addition to its importance within cells, cholesterol also serves as a precursor for the biosynthesis of steroid hormones, bile acids, and vitamin D. Cholesterol is the principal sterol synthesized by animals.holesterol is oxidized by the liver into a variety of bile acids. These, in turn, are conjugated with glycine, taurine, glucuronic acid, or sulfate. A mixture of conjugated and nonconjugated bile acids, along with cholesterol itself, is excreted from the liver into the bile.

Winterization of oil Winterization of oil is a process of removing of the higher melting point parts from oil like waxes or triglycerides by slowly cooling vegetable oils and felling saturated glycerides from the solvent. Used primarily for oils in salad dressings. Mainly applied in Bioindustry.

Cholestasis Cholestasis is a condition where bile cannot flow from the liver to the duodenum. Pruritus is the primary symptom of cholestasis and is thought to be due to interactions of serum bile acids with opioidergic nerves. 2  In fact, the opioid antagonist naltrexone is used to treat pruritus due to cholestasis. 3  jaundice.

Cholesterol, Lipoproteins and the Liver The liver is central to the regulation of cholesterol levels in the body. Not only does it synthesize cholesterol for export to other cells, but it also removes cholesterol from the body by converting it to bile salts and putting it into the bile where it can be eliminated in the feces. The liver removes LDL and other lipoproteins from the circulation by receptor-mediated endocytosis. 2  Additionally, excess cholesterol from cells is brought back to the liver by HDL in a process known as reverse cholesterol transport (green pathway).

What is Cholecystokinin? Cholecystokinin or CCK is a hormone produced by the digestive tract, mostly in the small intestine. It plays a role in the digestion of proteins and fats, and it also has an effect on the brain and vagus nerve, generating feelings of satiety which are designed to shut down the appetite once someone has eaten enough.

What Are the Cholesterol Functions? Its functions are as follows: 1  Hormone production. Cholesterol plays a part in producing hormones such as estrogen, testosterone, progesterone, aldosterone and cortisone. 2  Vitamin D production. Vitamin D is produced when the sun’s ultraviolet rays reach the human skin surface.  Bile production.

17 Loading and Transformation in Data Warehouses Multistage Data Transformation in Data Warehouses. The data transformation logic for most data warehouses consists of multiple steps. For example, in transforming new records to be inserted into a sales table, there may be separate logical transformation steps to validate each dimension key. Figure 17-1 offers a graphical way of looking at the transformation logic.

- Squalene is converted to cholesterol. Pathway of cholesterol biosynthesis. Synthesis of cholesterol begins with the transport of acetyl-CoA from within the mitochondria to the cytosol. The rate limiting step in cholesterol synthesis occurs at the 3-hydroxy-3-methylglutaryl-CoA (HMG-CoA) reducatase, HMGR, catalyzed step.YP metabolism of cholesterol yields several oxysterols that function as biologically active molecules such as in the activation of the liver X receptors (LXRs) and SREBP (see the next section). CYP3A4: CYP3A4 is also known as glucocorticoid-inducible P450 and nifedipine oxidase.

How Caterpillars Work This process of complete transformation is known as holometabolism. The amount of time required to transform completely varies from one species to another, but in general it takes about two weeks. For species that survive the winter by staying in the chrysalis, it can take months.

Overview Cholecystectomy (koh-luh-sis-TEK-tuh-me) is a surgical procedure to remove your gallbladder — a pear-shaped organ that sits just below your liver on the upper right side of your abdomen.holecystectomy is most commonly performed by inserting a tiny video camera and special surgical tools through four small incisions to see inside your abdomen and remove the gallbladder. Doctors call this laparoscopic cholecystectomy.
