PPT-Hypersenstivity Reactions Part 1

Definition Injurious consequences in the sensitised host following subsequent contact with specific antigens Gell and Coombs Classification   Type I Type II Type III Type IV Immune response altered. In addition to substitution, alkyl halides can also undergo elimination reactions, which lead to the formation of alkenes.. As with substitution reactions, elimination reactions come in two mechanistic types:. If a set of chemical reactions is taking place in a system, a . complete. mathematically independent sub-set is one where every reaction that is . not. included in the complete mathematically independent sub-set can be written as a linear combination of the reactions that . Chemical change. . Reactions with acid. . Reactions with oxygen . 7F. 7F Simple chemical reactions. Chemical change. . 7F Simple chemical reactions. 7F Chemical change – Changing materials. How many different materials can you see in this bedroom?. In general, we look at what occurs and try to learn how it happens. Common patterns describe the changes. Addition reactions – two molecules . combine. Elimination reactions – one molecule splits into two. Simon Yates, AstraZeneca. . FreeSlate European User Meeting. 24. th. September 2013. Our Journey so far. …. We produce a scalable process, not just a compound. From a few grams in the lab to multi-kilo plant campaigns . Part . 1: Decomposition and Synthesis Reactions. . Objectives. -To identify decomposition and synthesis chemical reactions. -To predict the products of these two types of reactions. 2. Symbols in . Free Radicals. Chain Free Radical Reactions. Nonchain. . Free Radical . Reactions. Miscellaneous . Free Radical Reactions. . Chapter Five. Free Radicals. Properties of free radicals. 1. One or more unpaired electrons.. Envenomations. Chapter 16. Allergic Reactions. Allergic reaction. Exaggerated immune response to any substance. Histamines and . leukotrienes. Chemicals released by the immune system. Anaphylaxis. Extreme allergic reaction. Alkenes. The commercial . process. of . hydrogenation is . used. to . convert the double . bonds. in . vegetable oils to . saturated. fats . such as those in margarine. . Learning . Goal . . Draw the condensed or line-angle structural formulas and give the names for the organic products of addition reactions of alkenes. Draw a condensed structural formula for a section of a polymer.. Synthesis reactions. Decomposition reactions. Single replacement reactions. Double replacement reactions. (Precipitate reaction). Chemical Reactions can be written as:. Word equation. Chemical equation. Changes or transforms chemicals into . other. chemicals. Ex: Iron + Oxygen . . Iron Oxide (rust). Physical Science Review. What is the product?. What are the reactants?. Chemical formula. . shows the kind and proportion of atoms of each element that occurs in a particular compound. Our estimates of pressures and temperatures experienced by rocks during metamorphism are based on metamorphic reactions.. Mineral Reactions. There are two basic types of mineral reactions:. Continuous. These are the OPPOSITE of neutralization reactions (i.e. acid-base reactions). Rather than forming a salt and water from an A-B reaction, a salt and water react to form an acid and a base.. You MUST determine if you have a Strong or Weak Acid and a Strong or Weak Base.. All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. .
