Endocrinology – Case study 1 A 37 year old female with a recent history of dizziness‚ shakiness and intolerance to heat and sees her GP. Her blood tests come back as normal apart from a thyroid stimulating hormone (TSH) of <0.05 mU/l and free thyroxine (T4) of 30.1 pmol/l. Normal Ranges of TSH‚ T4‚ and T3 The results received from the patient blood tests indicate abnormal levels of these hormones. The reference ranges of these hormones are: TSH has a range of 0.4-4.5 mU/l‚ free T4 has a range of

Electrophilic addition causes N2 to be lost‚ which is a thermodynamically favourable process‚ resulting in the formation of a stable carbene. The carbene is the intermediate and in this reaction‚ it is a highly reactive‚ neutral molecule. The carbene acts as

oxidation of benzoin. In order to produce the desired o-diketone‚ the alcohol on benzoin must be oxidized. Nitric acid was the oxidizing agent used in this experiment. As a result‚ the alcohol group on benzoin acted as the nucleophile and attacked the electrophilic nitrogen of nitric acid. As this step forms oxonium‚ excess water in the system deprotonated the oxonium to restore the neutral charge on oxygen. However‚ the organic nitrate was unstable due to its positively charged nitrogen. To stabilize the

alkenes. Alkanes only contain c-c single bonds‚ are saturated‚ and are the least reactive. Alkenes are c=c double bonds‚ more reactive than alkanes‚ and unsaturated. In the next part of the experiment we added bromine to alkenes. This caused an electrophilic halogenation reaction. If the bromine reacted with the alkene the bromine would discolor from orange and turn clear.

Lab 1: Synthesis of Aspirin Introduction: The purpose of this lab was to demonstrate the ability to easily alter the molecular structure of a compound to greatly increase its utility. In this case‚ an acetyl group was added to salicylic acid‚ a naturally occurring compound with significant pharmaceutical value. Without the addition of the acetyl group‚ salicylic acid is an irritant to the gastro-intestinal (GI) tract. Once the acetyl group is added via a simple reaction‚ acetylsalicylic

13. ORGANIC CHEMISTRY IV) ALKYNES SYNOPSIS Alkynes are commonly known as acetylenes. Acetylene is the simplest and important member of the alkyne series. • Alkynes contain – C ≡ C – • General molecular formula of alkynes is CnH2n–2 • Triple bonded carbons are ‘sp’ hybridized and greater s – character is associated with it. • Alkynes will exhibit chain‚ position and functional isomerism. • Their functional isomers are alkadienes and cyclo alkenes. • The minimum number of carbons required to exhibit
