uses of fatty acids

Fatty acids with long hydrocarbon chain carboxylic acid. Usually in the form of esters of various lipid components to form free fatty acids in nature are rare, the most common fatty acids in the table below. Most fatty acids containing an even number of carbon atoms, because they are usually from 2 carbon units biosynthesis. Higher animals and plants the most abundant fatty acids containing 16 or 18 carbon atoms, such as palmitic acid (palmitic acid), oleic acid, linoleic acid and stearic acid. More than half of animal and plant lipid fatty acids as unsaturated fatty acids containing double bonds, and often more than double bonds of unsaturated fatty acids. Bacterial fatty acid double bonds, but often there is little hydroxylation, or contain branched chain, or containing cyclopropane ring structure. Some vegetable oils and waxes containing unusual fatty acids. Unsaturated fatty acids must have a double bond at C (9) and C (10) between (starting from the carboxyl carbon atoms). Fatty acid cis-double bond is almost always the geometry, which allows the hydrocarbon chain of unsaturated fatty acids, about 30 ° bend, interfere with the accumulation time they fill space efficiently, results in reduced van der Waals interactions, giving the melting point of fatty acids with its degree of unsaturation increases. Lipid mobility with the unsaturated fatty acids increase, the nature of this phenomenon on the membrane have a major impact. Saturated fatty acids are very flexible molecules, in theory, each C-C bonds around relatively freely able to rotate, and thus a wide range of some conformation. However, its fully extended conformation with the energy of the smallest, most stable; because the conformation of the methylene adjacent to steric hindrance between the minimum. And most of the substances, the melting point of saturated fatty acids with the molecular weight increases.
Animals can synthesize saturated fatty acids and linoleic acid required to contain only one type of double bonds of unsaturated fatty acids, containing two or more double bonds or more double bond fatty acids must be obtained from plants, so the latter said for the essential fatty acids, linolenic acid and linoleic acid in which the most important. Arachidonic acid from linoleic acid generation. Arachidonic acid is the precursor of most prostaglandins, prostaglandin can regulate cell function is hormone-like substances.
Fatty acids can be used for the production of styrene butadiene rubber emulsifiers and other surfactants, lubricants, gloss agents; can also be used to produce advanced soap, transparent soap, stearic acid and various surfactant intermediates.

what is β-Defensin-2 (human recombinant)

The β-defensins are small, cysteine-rich, cationic peptides expressed throughout the epithelia of many organs. Expression of these defensin genes is regulated in response to infection and inflammation. β-defensins play important roles along with α-defensins in the human primary defense system against infection. They have been reported to link innate and adaptive immunity by attracting immature dendritic cells and memory T-cells. The antimicrobial, antiviral, and immunomodulatory properties of β-defensins increase resistance to infection. Due to their unique mechanism of action, β-defensins are expected to be ideal therapeutic agents as peptide antibiotics, mitigating the problem of acquired resistance.

How to Prevent Nocardia Infections

The following steps show you how to prevent Nocardia infection.
  1, using trimethoprim-sulfamethoxazole (TMP-SMX) as prophylaxis in patients with AIDS, chronic granulomatous disease and other diseases immunocompromising. This is usually for the purposes of prevention of Pneumocystis pneumonia. Be aware that this therapy can reduce the symptoms of Nocardia and complicate a diagnosis.
   2, use of chronic suppressive therapy with TMP-SMX to prevent recurrence of Nocardia infection. Recurrence of infection is the most common complication of nocardiosis so it is very important to complete the entire treatment. A CD4 cell count below 200 cells / ml should decrease the incidence of nocardiosis in these patients.
   3rd Treat mild cases for at least six weeks, while severe infections may need to be treated for one year. All treatment should be continued until at least one month after all signs of infection have subsided.
   4, Nocardia expect to be at least partially resistant to antibiotics during prolonged treatment.
   5, Consider the use of corticosteroids in the prevention of pulmonary nocardiosis. AIDS drugs in the smallest doses and for the shortest time that is effective should be used.

What is a Calcium Channel?

A calcium channel is a structure in the body, the cells to transmit electrical charges can be mutually exclusive. These fees are performed on a calcium ion, which can travel freely back and forth through the calcium channel. There are a number of different types of calcium channels in order to break the speed and how they behave. This anatomical structure is part of a family of similar structures known collectively as ion channels.
  Calcium channels are found in places such as muscles, neurons and glial cells. These types of cells are known as "excitable" cells. Different calcium channels are working in different ways, but the general idea is that the structure of proteins, which is made ​​sensitive to electrical impulses. When proteins receive the right signal, they open the calcium-channel so that an ion flow to the channel in another cell.
  Ions carry a small electrical charge that can stimulate such a thing as muscle contraction, the release of a hormone or the firing of a neurotransmitter. At any given time thousands of ions to the calcium channels of the body are moving, signals of different activities, ranging from strokes to heart talk. Different types of calcium channels behave a little differently, react or sensitive to certain types of calcium ions, so that the body greater control over how and when these structures are active.

what is humectant

A humectant is a hygroscopic substance. It is often a molecule with several hydrophilic groups, most often hydroxyl groups, but amines and carboxyl groups, sometimes esterified, can be encountered as well; the affinity to form hydrogen bonds with molecules of water is crucial here.
Since hygroscopic substances absorb water from the air, they are frequently used in desiccation or for humidity buffering.
When used as a food additive, thehumectant has the effect of keeping the foodstuff moist.Humectants are sometimes used as a component of antistatic coatings for plastics. Humectants are also found in many cosmetic products where moisturization is desired, including treatments such as moisturizing hair conditioners and also commonly used in body lotions.
Humectants are also used in the manufacture of some cigarettes and other tobacco products.
Humectants are also used in topical dosage forms to increase the solubility of the active ingredient, to elevate its skin penetration and increase its activity time. It also elevate the hydration of the skin to minimize the dehydrating effect of some active ingredients like corticoids.
Examples of humectants include glycerol, propylene glycol (E1520), and glyceryl triacetate (E1518). Others can be sugar polyols like sorbitol (E420), xylitol, and maltitol (E965), polymeric polyols like polydextrose (E1200), or natural extracts like quillaia (E999), lactic acid, or urea.
The chemical compound lithium chloride is an excellent humectant, but is toxic.

what is FABP5 (murine recombinant)

Fatty acid-binding protein, epidermal is a protein that in humans is encoded by the FABP5 gene.
This gene encodes the fatty acid binding protein found in epidermal cells, and was first identified as being upregulated in psoriasis tissue. Fatty acid binding proteins are a family of small, highly conserved, cytoplasmic proteins that bind long-chain fatty acids and other hydrophobic ligands. It is thought that FABPs roles include fatty acid uptake, transport, and metabolism.FABP5 has been shown to interact with S100A7.
