Type in a word or phrase to search, you can also type in Article ID's separated by commas:

Enzymes are proteins that catalyze (i.e., increase the rates of) chemical reactions.[1][2] In enzymatic reactions, the molecules at the beginning of the process are called substrates, and the enzyme converts them into different molecules, called the products. Almost all processes in a biological cell need enzymes to occur at significant rates. Since enzymes are selective for their substrates and speed up only a few reactions from among many possibilities, the set of enzymes made in a cell determines which metabolic pathways occur in that cell.

Like all catalysts, enzymes work by lowering the activation energy (Ea) for a reaction, thus dramatically increasing the rate of the reaction. Most enzyme reaction rates are millions of times faster than those of comparable un-catalyzed reactions. As with all catalysts, enzymes are not consumed by the reactions they catalyze, nor do they alter the equilibrium of these reactions. However, enzymes do differ from most other catalysts by being much more specific. Enzymes are known to catalyze about 4,000 biochemical reactions.[3] A few RNA molecules called ribozymes also catalyze reactions, with an important example being some parts of the ribosome.[4][5] Synthetic molecules called artificial enzymes also display enzyme-like catalysis.[6]

Enzyme activity can be affected by other molecules. Inhibitors are molecules that decrease enzyme activity; activators are molecules that increase activity. Many drugs and poisons are enzyme inhibitors. Activity is also affected by temperature, chemical environment (e.g., pH), and the concentration of substrate. Some enzymes are used commercially, for example, in the synthesis of antibiotics. In addition, some household products use enzymes to speed up biochemical reactions (e.g., enzymes in biological washing powders break down protein or fat stains on clothes; enzymes in meat tenderizers break down proteins, making the meat easier to chew).

As early as the late 1700s and early 1800s, the digestion of meat by stomach secretions[7] and the conversion of starch to sugars by plant extracts and saliva were known. However, the mechanism by which this occurred had not been identified.[8]

November 05, 2009

Viagra Professional (Generic) is a latest created generic version of Viagra that is patently improved compared with the branded Viagra. Viagra Professional still is made of the foremost substance in the solution of erectile failure, Sildenafil Citrate, which cancels out the consequences of the enzyme phosphodiesterase type 5. This biomolecule, restricts blood from getting to the penis all through sexual activity. Sildenafil Citrate stops the production of Phosphodiesterase, making it possible for the blood to run liberally to the penis veins, ensuing in the success of a penile erection for eno... (read more)

Inflammation is anything in the body that should not be there. Any "non living tissue". And quite simply, this is just about anything that causes pain. Blockages, such as in the head or chest from mucus, like catarrh, sinus or bronchial problems, asthma, emphysema, or industrially induced problems including asbestosis.

5. The ELISA Kit - A Powerful Tool For Modern Science
October 23, 2009

ELISA is short for Enzyme Linked Immuno Sorbent, and up until now the ELISA kit is the safest and fastest way of diagnosing various types of infectious diseases in humans. The ELISA kit, in one of its many forms, can also be used to diagnose various diseases in plants and animals also. The ELISA test can be viewed much like the pregnancy test, because it works pretty much in the same way. The most common use for the ELISA kit is detecting antibodies and antigens in samples, in the field of immunology. Apart from using the ELISA kit to run toxicology tests which quickly reveal the presence or a... (read more)

8. Feeding Dogs Dairy Products
October 08, 2009

Whether or not dogs can eat dairy products such as milk, Yoghurt and cheese is one of the most commonly asked questions from new dog owners. Unfortunately there is no concise answer to this, since individual dogs vary. The most abundant sugar in dairy products is lactose, which is a disaccharide that consists of bonded galactose and glucose fragments and which requires an enzyme called lactase to be able to digest it. The enzyme cleaves the lactose molecule into its two subunits, the simple sugars glucose and galactose, which can then be readily absorbed. When a mammal's body does not sec... (read more)

11. How To Stop Hair Loss - Male Pattern Baldness?
October 01, 2009

DHT or dihydrotestosterone is the ultimate cause for male pattern baldness. Testosterone that is in the bloodstream combines with an enzyme which your body produces known as 5 alpha reductase.

Male pattern baldness can be treated with advanced hair treatment therapies such as hair restoration and laser treatments. People suffering from hair baldness due to DHT should control their stress. Stress causes hormonal imbalances that may increase the output of DHT. People often live in a fallacy that male pattern baldne... (read more)

17. Hair Loss Products for Women - Are They Effective?
September 10, 2009

Women may experience hair fall or thinning of hair. If you have telogen effluvium then you will experience hair loss. Certain enzymes in male and female are genetically predisposed to hair fall. It is known as 5-alpha reductase enzyme. This enzyme coverts the testosterone hormone into another hormone known as DHT or dihydrotestosterone. This dihydrotestosterone gets attached to the hair lobe on the top of the head. This further weakens the hair follicle damaging the hair growth with every hair growth cycle. Your hair grows thinner day by day and leads to baldness. Hair loss products such as Pr... (read more)

The rising numbers of children with autism could be a warning. Genetically, these children may be especially sensitive to some of the tens of thousands of pollutants in our environment. According to Discover magazine, autism researchers have begun paying attention to the digestive and immune disturbances that accompany the personality aberrations of autism. Autism is probably connected to genetics. That’s “genetics,” not “a gene.” And autism is probably connected to environment. Like most genetic phenomena, it’s a combination of nature and nurture.

21. Lactofree: enjoy the taste of milk without lactose
August 31, 2009

It is currently estimated that up to 15% of the UK population suffer from lactose intolerance.1 Many more sufferers are not even aware of their intoler¬ance. It is caused by a deficiency of lactase, an enzyme present in the lining of the small intestine which is needed to absorb and digest lactose (milk sugar). Lactase breaks down lactose into simpler forms of sugar called glucose and galactose (which is metabolised in the liver to glucose) which can be absorbed into the bloodstream. The body needs sugar as a source of fuel, but the only sugar the body is able to use is glucose. Therefore a... (read more)

.The amount of fat you carry around is not determined by your genes, but by what you do and what you eat. Recent scientific studies has shown that neither the number of fat cells nor their seize is genetically fixed, but body fat is dependent on lifestyle. Your body has no internal reference for a permanent level of fat, only for a habitual level. When you remain at a particular fat level for a year or more, your body develops all the adipore cells, capillaries, enzyme counts, periphal nerves,hormone levels and connective tissues to support it.
