pyrimidines: CUT the Caramel Apple pie
CUT= C,U,T and pie=py
Caramel = Carbamoyl phosphate
Apple= Aspartate
-----------
Purines: Pure As Gold, Glitz And Glam
As Gold = A,G Pure = purine
Glitz = Glycine
And = Aspartate
Glam = Glutamine
sorry for the inactivity. this is where im going to upload boards review stuff for awhile.

NASA Scientists Cook Up Building Blocks of Life in Lab
Many of the chemical ingredients necessary for life as we know it were available on the early Earth, and should be present on exoplanets as well, new research suggests. Researchers at NASA's Ames Research Center in California generated three key components of RNA (ribonucleic acid) and DNA (deoxyribonucleic acid) in the lab, by exposing commonly occurring ring-shaped molecules of carbon and nitrogen to radiation under spacelike conditions. "Nobody really understands how life got started on Earth," Scott Sandford, a space science researcher at Ames, said in a statement. The rings hold carbon atoms, but the presence of nitrogen makes pyrimidine less stable than other carbon-rich compounds, researchers said. http://dlvr.it/9NrFbm

Importer and Distributor of all types Research Chemicals or Biochemical
Research chemicals are needed with other pharmaceutical supplies in the current scenario. With the requirement of those chemicals and pharmaceutical drug ingredients have a trusted source or perhaps a well known provider to deal good business needs a credible in all types of chemical provider. The quantity of chemical marketers is several however, only few of them tends to be immensely worried about the impact of supplying quality items; and, only few are understand on real welfare of their supply. It is very important that each research chemical meets these types of standards while packaging and marking, top high quality and authorized research chemicals, secure chemical transport and on-time shipping. This requires every research chemical distributor in addition to suppliers in order to abide using the environmental as well as conservation laws to be able to mitigate impacts about the environment due to manufacturing research chemicals substances. Here are few most demanding chemicals - (1) Boronic Acid • A boronic acid is an alkyl or aryl substituted boric acid containing a carbon– boron bond belonging to the larger class of organoboranes. • Boronic acids act as Lewis acids • Their unique feature is that they are capable of forming reversible covalent complexes with sugars, amino acids, hydroxamic. • Boronic acids are used extensively in organic chemistry as chemical building blocks and intermediates predominantly in the Suzuki-coupling. • Small molecules containing boronic acid moieties are potential therapeutics for the treatment of breast cancer, including multi-drug resistant breast cancer. The compounds may be used alone or in combination treatments (2) Pyridine • Pyridine is a basic heterocyclic organic compound. • The pyridine ring occurs in many important compounds, including azines and the vitamins niacin and Pyridoxal. • Pyridine is used as a precursor to agrochemicals and pharmaceuticals and is also an important solvent and reagents. • It is used in the in vitro synthesis of DNA and synthesis of sulfapyridine (a drug against bacterial and viral infections • pyridine serves as a building block for making a variety of drugs, insecticides and herbicides. • Pyridine is also the starting compound for the preparation of pyrithione-based fungicides. • Cetylpyridinium and laurylpyridinium, which can be produced from pyridine with a Zincke reaction, are used as antiseptic in oral and dental care products. (3) Pyrimidine • Pyrimidine is a heterocyclic aromatic organic compound containing two nitrogen atoms at positions 1 and 3 of the six-member ring. • The three nucleotides found in nucleic acids namely Cytosine (C), Thymine (T) and Uracil (U) are pyrimidine derivatives.
(4) Amino acid • Amino acids are molecules containing an amine group, a carboxylic acid group, and a side-chain that is specific to each amino acid.. • Amino acids serve as the building blocks of proteins, which are linear chains of amino acids. Amino acids can be linked together in varying sequences to form a vast variety of proteins. • The chelating ability of amino acids has been used in fertilizers for agriculture to facilitate the delivery of minerals to plants in order to correct mineral deficiencies, such as iron chlorosis. These fertilizers are also used to prevent deficiencies from occurring and improving the overall health of the plants. • Unnatural amino acids, utilized as building blocks, conformational constraints, molecular scaffolds or pharmacologically active products. (5) Piperidine • Piperidine is a heterocyclic amine consists of a six-membered ring containing five methylene units and one nitrogen atom. • piperidine is used for the production of dipiperidinyl, dithiuram ,tetrasulfide, which is used as a rubber vulcanization accelerator. (6) Phenol • Phenol, also known as carbolic acid and phenic acid. It is a white crystalline solid at room temperature. • Phenol is also a versatile precursor to a large collection of drugs, most notably aspirin but also many herbicides and pharmaceuticals. Phenol is also used as an oral anesthetic/analgesic, commonly used to temporarily treat pharyngitis. • Phenol derivatives are also used in the preparation of cosmetics including sunscreens, hair dyes, and skin lightening preparations Labex Corporation a well known importers and suppliers of Research Chemicals, Elisa Kits, recombinant proteins, antibodies, Biochemicals, Screening Compounds from across the Globe and distribute it according to the need of our clients which are base of over 500 plus Pharma Companies in all over India.
