Organic Chemistry - Introduction 1 2812 Basic definitions for organic chemistry Scope Organic chemistry is a vast subject so it is easier to split it into small sections for study. This is usually done by studying compounds which behave in a similar way because they have a particular atom‚ or group of atoms‚ (FUNCTIONAL GROUP) in their structure. Catenation The ability to form bonds between atoms of the same element. Carbon catenates to form chains and rings‚ with single‚ double

INTRODUCTION : Human “PKNOX” gene is a homeobox gene (1)‚ belongs to the homeobox gene family‚ involved in the regulation of development of animals. It is also known as “PREP”. They play important roles in different steps of body pattern formation during early embryogenesis of animals. Homeobox genes are generally highly conserved and control similar phenotypic characters among distantly related organisms (2). However‚ they are also responsible for controlling different phenotypic characters

Protein in nature and in action specific; rapid and accurate; huge in size but with small active centres; highly exploited for disease diagnosis in lab centres”. DEFINITION Enzymes may be defined as biocatalysts synthesised by living cells. They are protein in nature (exception RNA acting as ribozyme) colloidal and thermo-labile in character and specific in their action. HISTORICAL BACKGROUND In

Importance of colloidal dispersion in pharmacy Pharmaceutical Applications of colloids: Colloids are extensively used for modifying the properties of pharmaceutical agents. The most common property that is affected is the solubility of a drug .However‚ colloidal forms of many drugs exhibits substantially different properties when compared with traditional forms of these drugs. Certain medicinals have been found to possess unusual or increased therapeutic properties when formulated in the colloidal
