Organic Chemistry Recognizing the 4 main classes of organic molecules. Organic Compounds An organic compound is any compound that contains atoms of the element carbon. Carbon has 2 electrons in its 1 st energy level and 4 electrons in its 2 nd energy level. Carbon

Membranes & Proteins Can lead to the formation of excess CHOLESTEROL Steroid that helps stabilize membranes of animal cells So why are saturated fats bad for me? Is there such a thing as a “good” fat? Polyunsaturated fats (>1 double bond) contain essential fatty acids (omega-3)

Structure of proteins by X-ray crystallography. George N. Phillips, Jr. ECE 532 Spring 2005. Points to be covered. What are proteins? How they are organized? How do we know their three-dimensional structures? Why do you need a crystal and how does one get a crystal?.

Chapter 20, part A. Antimicrobial Drugs. Antimicrobial Drugs. Chemotherapy The use of drugs to treat a disease Antimicrobial drugs Interfere with the growth of microbes within a host Antibiotic Substance produced by a microbe that, in small amounts, inhibits another microbe

단백질 특성. Amino Acid Nomenclature. 단백질은 모든 종에 걸쳐 20 개의 아미노산 레퍼토리로 구성되어 있다 . 20 종류의 측면 사슬들은 크기 , 모양 , 전하 , 수소 결합 용량 , 소수성 특성 , 그리고 화학적 반응에 의해 다양하다. achiral (non-chiral). Most Simple Amino Acids. Most Typical Aliphatic Amino Acids. Most Typical Non-Polar Hydrophobic Amino

Amino Acids and Proteins. Structure of amino acids. The hydrolysis of most proteins produces about twenty different amino acids. The acids have an amino group bonded to the  carbon:-. an  -amino acid. Amino acid classification. The 20 amino acids are further classified:.

Biology. The Molecules of Cells. Carbon and Functional Groups Why is Carbon Important? A. What is Organic Chemistry? The study of carbon compounds is know as Organic Chemistry Organic molecules are molecules that contain carbon. A Look at History

Biochemistry. Lysozyme – a protein. Carbohydrates. There are two types of carbohydrates: The simple sugars Glucose, sucrose, fructose (and many others) The complex carbohydrates. Carbohydrates that are made of long chains of sugars Starches, cellulose . Simple Sugars.

Notes for 8/30 Parts of CH3 and 4: Review of Bio 241/242. Please also review the cell structure power point for cell structure review materials which are also important. Peptides: bonds and structure Nucleosides: ATP, GTP, DNA Carbohydrate classes: mono, di and poly

Biosynthesis of protein (translation). Materials involved in the translation (1) mRNA a. genetic code b. the category of genetic code. c. Triplet code d. Open reading frame (ORF) c. character of the genetic code. * non-spacer,non overlap

Amino Acids. Dehydration reaction ( condensation ) -- two amino acids linked together. enzymes necessary link is between carboxyl group on one a.a. and the amino group on the other. water is formed and remaining N and C link together with a peptide bond

Chapter 3. Amino acids, peptides, and proteins. Properties of Amino Acids. capacity to polymerize novel acid-base properties varied structure and chemical functionality chirality. carboxyl group. amino group. a -carbon. side chain. Basic Amino Acid Structure.

Water. H-Bonding Angle (linear = strongest) Distance (between donor and acceptor) Partial Charges on Participants Dielectric Constant ( E ) (a measure of a solvent’s ability to shield charges) F = kq 1 q 2 E r 2 Polar: E >15 Apolar: E <15. High Boiling Point

The Raw Materials of Biotechnology. Learning Outcomes. Identify the levels of biological organization and explain their relationships Describe cell structure and its significance in biotechnology research and product development

Amino acids. Met dank aan Dr. Detke. Most amino acids are chiral. All naturally occuring amino acids except Gly are the L isomer L & D amino acids are stereoisomers. Most amino acids are zwitterions. amino acids are zwitterions at neutral pH (contains negative and positive charged groups).

Chapter 6 : The Chemistry of Life. Everything is made up of Elements. Elements are made up of only one type of atom 96% of the atoms in the human body are either: Carbon, Hydrogen, Oxygen or Nitrogen. Mixtures and Solutions.
