Fenn, Koichi Tanaka, Kurt W?thrich ( nglish Swedish Popular Information Information for tK H PuEliF 9 October 2002 The Nobel Prize in Chemistry for 2002 is being shared between scientists in two important fields: mass spectrometry (MS) and nuclear magnetic resonance (NMR). The Laureates, John B. Fenn and Koichi Tanaka (for MS) and Kurt W?thrich (for NMR), have contributed in different ways to the further development of these methods to embrace biological macromolecules. This has meant a revolutionary breakthrough, making

Campbell Biology 9th Edition chapter04 test Bank with Answer

Campbell's Biology, 9e (Reece et al.) Chapter 4 Carbon and the Molecular Diversity of Life This chapter focuses on the chemistry of carbon and organic compounds. Students should be able to identify the nature of the bonds between carbon and other elements (nonpolar versus polar), the different types of weak bonds and interactions, the various types of isomers, the basic functional groups of organic molecules, and their relative solubility in water. The abiotic formation of organic molecules from inorganic molecules is important in the origin of life. Multiple-Choice Questions 1) The element present in all organic molecules is A) hydrogen. B) oxygen. C) carbon. D) nitrogen. E) phosphorus. Answer: C Topic: Concept 4.1 Skill: Knowledge/Comprehension

Lecture 2 (Chapter 4 & 25) Atomic Structure Democritus (400 BC) ? Postulated there must be some basic unit of matter that could not be divided any further. ? Basic unit ? atomos (Greek = indivisible) Dalton Dalton?s Atomic Theory ? All matter is composed of extremely small particles called atoms ? All atoms of a given element are identical having the ame size, mass and chemical properties. Atoms of a specific element are different from those of any other element ? Different atoms combined in simple whole number ratios to form compounds ? Ina chemical reaction, atoms are separated, combined, or rearranged ? Atoms cannot be created, divided into smaller particles or destroyed. Scientist and Experiments Cathode Ray Tube Experiments ? Plum pudding model ?

Basic Building Blocks of Life Organic Molecules Organic molecules contain carbon and hydrogen atoms Both atoms can form hydrocarbon chains and rings The four major classes of organic molecules: carbohydrates, proteins, lipids and nucleic acids. ? Functional groups Functional groups are reactive molecules that usually contain oxygen, nitrogen, phosphorus or sulfur They are responsible for some of the unique properties of a molecule Some examples of functional groups Alcohols Aldehyde Amides Carboxyl groups Ketones Carbohydrates (basic building blocks of life) Carbohydrates These are organic molecules that contain carbon, hydrogen and oxygen Their general formula is CnH2nOn Carbohydrates are a source of energy Carbohydrates are also known as sugars They have a suffix of ?ose?

Chemistry Notes in Physiology Chemistry notes in Physiology: Atoms Atom?the basic unit of an element An atom consists of subatomic particles: Proton This has a ( + ) charge The number of protons in an atom is called atomic number Neutron This has no charge Electron This has a ( ? ) charge The number of electrons is usually equal to the number of protons ? Both the proton and the neutron are in the nucleus The sum of the proton and neutron is called atomic mass Shell = energy level 1st shell has 2 electrons 2nd shell has 8 electrons Valence electrons are the outermost electrons ? Isotopes = same atomic number, but different atomic mass Isotopes will differ in the number of neutrons For example: Hydrogen has 1 proton Deuterium has 1 proton and 1 neutron

Pre-AP Chemistry Modern Chemistry (2006) Chapter 1 Notes ? Matter and Change 1.1 Chemistry is a Physical Science 1. The natural sciences were once divided into two categories: biological and physical sciences. 2. The biological sciences focus on living things and their interaction with the environment. 3. The physical sciences focus is mainly on non-living things. 4. However, chemistry is central to all living and non-living things because they consist of chemical structures. 5. Chemistry is the study of the composition, structure, and properties of matter, the processes that matter undergoes, and the energy changes that accompany these processes. Branches of Chemistry 1. Chemistry includes six branches of study ? although these branches often overlap.
