  Terpenoids :                  Any of the class of the organic compounds including terpenes, diterpenes, and sesquiterpenes. They are unsaturated   molecules composed of linked isoprene units, generally having formula (C 5 H 8 )n.    Application of terpenoids:            the applications of the terpenoids in detail are following below; In Medicine :            A method of medicinal treatment for a medical condition in a mammals, said condition being selected from the group consisting of viral infections, bacterial infection, fungal infection dermatoses indolent neoplasma sunburns burn and swollen joints said method comparising the parental applications to said mammals of a pharmacologically effective amount for treatment of said condition of an ozonide of a terpene in a pharmacologically acceptable carrier. In industry:               Terpenoids represents the oldest known biomolecules having been recoverd from the sediments as old as 2.5 billion years among plant sec

  Applications of Gas chromatograph   Applications of gas chromatography are as following: 1. Qualitative analysis :    By comparing the retention time or volume of the sample to sample to the standard/ by collecting the individual components as they emerge from the chromatography and identifying these compounds by other methods like UV, IR, NMR. 2. Quantitative analysis :                                         Area under a single component elution peak is proportional to the quantity of the detected component /   response factor of the detectors. a.   Direct comparison method: A (sample) / A (std) = αC (sample) /C (Std) Where, α is the response factor determined for every pure compound under given conditions. b.   Calibration curve: A graph is plotted   by taking peak areas on y-axis and concentration of standard compounds on x-axis. Concentration of the unknown sample is then determined by putting the value of its peak area on same graph. C.   Internal sta

  Application of heterocyclic compounds In an organic chemistry, largest families of organic compounds are belongs in the heterocyclic compounds. In our daily life important of heterocyclic compounds are of very essential. It has broad range of application in medicinal chemistry and in agrochemicals products. Applications of the heterocyclic compounds in detail are following below; 1.       Medicinal chemistry: Heterocyclic have been found a key structural in medical chemistry and also they are frequently found in large percent in biomolecules such as enzyme, vitamins, natural products and biological active compounds including antifungal, anti-inflammatory, antibacterial, antioxidant, anti-convulsant, anti-allergic, enzyme inhibitors, herbicidal activity, anti-HIV, anti-diabetic, anticancer activity, insecticidal agents. ·          Antifungal activity: It is substances or medications that used to treats the fungal infection which is most commonly located on the skin, ha

  Alkaloids       Alkaloids are a class of naturally occurring organic compound that mostly contain basic nitrogen atoms. Alkaloids are produced by a large variety of organisms including bacteria, fungi,   plants and animal.          Applications of alkaloids: In pharmaceutical:         Alkaloids are used in the regulation of microbial and schizonticide activity and as pharmaceuticals. Medical use of alkaloids containing plants has a long history and thus, when the first alkaloids were isolated in 19 th century, they immediately found application in clinical practice. Many alkaloids are still used in medicine, usually in the form of salts widely used including   the following. Alkaloids  Caffeine Physotigmine  Tubocurraine   There Actions Stimulant, adenosine receptor antagonist. In hibitor of acetylcholinesterase. Muscle relaxant.  Many synthetic and semisynthetic drugs are structural modification of the alkaloids, which were designed to enhance or change primary ef

  What is Coulometry ? Coulometry is an analytical  method  for measuring an unknown  concentration  of an analyte in  solution  by completely converting the analyte from one  oxidation   state  to another.  Coulometry  is an absolute measurement similar to gravimetry or  titration  and requires no chemical  standards  or  calibration . It is therefore valuable for making absolute  concentration  determinations of  standards .   Coumetry uses constant  current   source  to deliver a measured amount of  charge . One  mole  of electrons is equal to 96,485 coulombs of charge, and is called a  faraday . Basic Principle : The main principle involved in the coulometry is the measurement of the quantity of the electricity which is directly proportional to the chemical reaction at the electrode. This is given by the Faraday's first law:where Q is the consumed current; Mr is the relative molecular weight.   Concept Of Coulometry : In coulometry, the current, created by analyte exh
