Sucrose Synthesis by D. DeWitt‚ PhD v1.5 11/10/12 Introduction | Condensation Reaction | Plant Synthesis | A. Introduction Although it might seem straight forward‚ the synthesis of sucrose‚ either as a simple condensation reaction (a.k.a. dehydration synthesis)‚ or what actually happens in plants is complicated. Before we explore sucrose’s creation‚ let’s take a look at its structure. In Figure 1‚ the space-filling model is pretty but rather useless at this point in our journey. We

CHEM3412 Synthesis of a Porphyrin Porphyrins are hetereonuclear‚ macrocyclic compounds that play an important role in living organisms. Examples include the non-protein heme portion of hemoglobin in animals whereby the lone pairs on nitrogen can bind to the oxygen-carrying iron. In plants‚ chlorophyll uses the vast conjugation to allow absorption of light for photosynthesis. The characteristic colors of porphyrins is also due to the conjugation. An examination of the porphyrin structure

1. a) Nursing research is one of the concepts mentioned in the video‚ Evidence-based practice‚ quality improvement‚ & nursing research. Nursing research is a systematic inquiry that uses disciplinary methods to answer questions and to resolve problems. The goal of nursing research is to generate new nursing knowledge. Nursing research is based on theory and the use of rigorous methods in order to conclude viable results (Hewner‚ 2013). The results are applied in a broad spectrum. Research publications

Introduction Cinnamaldehyde‚ cinnamic aldehyde or 3-phenyl-2-propenal is the major constituent of cinnamon oil‚ extracted from several species of Cinnamomum (C. verum‚ C. burmanii‚ C. cassia)‚ under the family Lauraceae‚ a group of evergreen trees. Cinnamon bark (particularly C. verum) yields 0.4-0.8% oil‚ which contains 60-80% cinnamaldehyde

THEORY X‚ Y AND Z IN NURSING ADMINISTRATION According to Mc Gregor‚ the traditional manager in a bureaucracy operates on a set of assumptions about human nature and human behaviour‚ which was called as Theory X. Accordingly‚ his assumptions are the following: (1) the average human being has an inherent dislike of work and will avoid it‚ if he can‚ when possible; (2) Because of dislike of a work‚ most people must be coaxed‚ controlled‚ directed‚ threatened with punishment to get through

Across Theory Concept Comparison and Analysis Across Theories Concept Comparison and Analysis Across Theories Nursing has evolved into a science. Like other scientific disciplines‚ the practice of nursing is guided by nursing theories. According to Julia George‚ “practice is based on the theories of the discipline that are validated through research” (George‚ 2011‚ p. 7). The major shift in theoretical thinking in nursing is said to occur in the 1960s when the focus in nursing shifted

What is MPTP and how is it used? MPTP is a form of synthetic analog drug that is only obtainable illegally. Demerol‚ also known as MPPP or MPTP is an analog of fentanyl and meperidine. When ingested‚ MPTP metabolizes into a reactive molecule in the brain that selectively destroys neurons containing dopamine‚ which found in the motor regions of the basal ganglia. Gradual neuronal degeneration is the result of Parkinson’s disease found in aging individuals however‚ the consumption of MPTP dramatically

Synthesis of Aspirin Name: Xuanyi Li Teaching assistant: Deirdre Zwilling November 15‚ 2009 Purpose: To synthesize aspirin‚ a common analgesic drug‚ via nucleophilic acid-catalyzed substitution reaction of salicyclic acid with acetic anhydride. The whole reaction is catalyzed by phosphoric acid. (The experiment involved three parts: The synthesis of aspirin‚ the isolation and purification of aspirin‚ and the estimation of the purity of the final product.) [pic] Procedure[1]: A mixture
