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

Hydrogel based controlled release formulations: Designing considerations‚ characterization techniques and applications. Abstract Hydrogels have evolved over the last decade as materials of choice in varied biomedical applications. This is associated with the inherent biocompatible nature of the hydrogels. The modulation of the properties of the hydrogels is easily possible due to the availability of polymers of varied chemistry and physical properties. This review discusses the pharmaceutical

The Biological Approach to Unipolar Depression. Katie Evans Abnormal behaviour was once thought to be caused by supernatural possession; this demonological model of abnormality was especially popular in the Middle Ages. It was not until the 18th century that psychologists began to argue that this behaviour should be treated as an illness and medical techniques could be used to treat it; and so emerged the medical model of abnormality. (Gross & McIlveen‚ 1996)1 The medical model of abnormal psychology

An old well-known method to stabilize a peptide sequences or protein motifs is N-terminal and C-Terminal modification to resistance against exo-nucleases cleavage. Due to its feasibility‚ we decided to perform this type of modification in order to stabilize synthesized sequences based on previous protocols. Understanding the appropriate compound and choosing the way of performance‚ were sensitive and definitely time consuming. Finally‚ N-terminal modification with 5(6) Carboxyfluorescein (FAM) in

Results indicate that the synthesized compound is (insert molecular formula here). 2.0 Synthesis of a Cobalt Complex. A cobalt(III) amine halide compound was prepared by treating solid CoCO3 with HBr to liberate Co(II) in solution. Ammonia and NH4Br were added‚ and the Co(II) oxidized to Co(III) with H2O2 yielding a wine colored solution from which 11.3 g of a solid‚ later identified
