Isomer

AHHHH CHOO-DOEPHEDRINE Although, originally defined as the chemistry of biological structures, organic chemistry has since been redefined to refer specifically to organic (carbon based) molecules. The hydrocarbon is the very basic molecule of organic chemistry and by adding functional groups to the hydrocarbon we can manipulate the properties of the molecule. Through the manipulation of these organic compounds, organic chemistry can be used to chemically synthesise many products such as soaps,…

Hello National Institute of Health, As you may know, Thalidomide can be a life-saving drug in certain cases such as Cancer and Leprosy however, this is only done in the case of absolute emergencies due to the very serious side effects it causes such as limb malformation and birth defects. The reason Thalidomide can simultaneously have such positive and negative effects will make more sense once we understand the mechanism for the acid hydrolysis of thalidomide. Initially thalidomide will be…

Chemistry has given me the opportunity to explore my interest in science and I enjoyed carrying out experiments in the lab which has improved my laboratory techniques. It has also enabled me to delve into topics that have fascinated me such as the optical isomer s-thalidomide and it's tragic teratogenic effect on the human body. A-levels maths has helped refine my problem solving and data handling skills. Psychology has broadened my research and debating skills as well as my ability to apply…

What four elements make up 96% of all living matter? _________________________________________ Concept 2.2 An element’s properties depend on the structure of its atoms 2.

Toluene diisocyanate (TDI) is an organic compound with the formula CH3C6H3(NCO)2. Two of the six possible isomers are commercially important: 2,4-TDI (CAS: 584-84-9) and 2,6-TDI (CAS: 91-08-7). 2,4-TDI is produced in the pure state, but TDI is often marketed as 80/20 and 65/35 mixtures of the 2,4 and 2,6 isomers respectively. It is produced on a large scale, accounting for 34.1% of the global isocyanate market in 2000, second only to MDI. Approximately 1.4 billion kilograms were produced in 2000…

Analysis Questions: 1. The primary reaction catalyzed by catalase is the decomposition of hydrogen peroxide to form water and oxygen, which occurs spontaneously, but not at a very rapid rate. Write a balanced equation for this reaction. Label the reactant and the product. (Remember that catalase is not a reactant or a product and can be written over the arrow separating the reactant from the products.) I will help you with the equation. Catalase 2H2O2…

Few decades ago, developments in health care have given to individuals to be more healthy and living longer. As a result, the number of people with non communicable diseases such as dementia is reduced. Despite dementia principally influence older people; it is not usual part of ageing. Dementia is a syndrome caused by a numerous of brain illnesses leading to loss memory, abnormal behavior, disability and cause extreme effect in individuals’ lives. Alzheimer disease (AD) is the major form of…

The problems that were identified in Mr. Elliot were his runny nose, cough, head, and chest congestion, frequent nose bleeds and multiple bruises to his arms and legs. He also had an elevated blood pressure of 180/90, chronic atrial fibrillation, elevated INR of 4.8, and elevated digoxin level 3.8. Mr. Elliot has chronic atrial fibrillation and is being treated with Warfarin. Warfarin is a Vitamin K antagonist, a blood thinner that is used to treat and reduce the chance of blood clots forming,…

The retinal pigment epithelium (RPE) is very a important part of the eye; It is responsible for absorption of scattered light, the visual cycle and phagocytosis of photoreceptor outer segment membranes. The protein RPE65 is normally abundantly made in the RPE, unless there is a mutation in the RPE65 gene, caused by a deletion of 4 base pairs. This deletion causes a frame shift and also an early stop on the protein, so the protein is shorter and does not function properly. The mutated gene is…

An insight in the biophysical properties of bio macromolecules Natural biopolymers such as nucleic acids, proteins and carbohydrates are essential for life as we see it today. It is incredible to think how this vast set of molecules that are in every living thing, from bacteria to human beings, are mostly made up by six elements (carbon, hydrogen, oxygen, nitrogen, sulfur and phosphorus). These biopolymers have the properties to, from small monomers, build giant tridimensional structures with a…
