Amino Acids Glycine is the smallest of the amino acids. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. In aqueous solution at or near neutral pH‚ glycine will exist predominantly as the zwitterion. Alanine is a hydrophobic molecule. It is ambivalent‚ meaning that it can be inside or outside of the protein molecule. The α carbon of alanine is optically active; in proteins‚ only the L-isomer is found. Serine differs from alanine in that one of the methylenic

Lab 5 DECOMPOSITION (Nov 2‚ 2011) Introduction: Decomposition is the breakdown of organic material into its smaller molecules and elements. (This term is generally considered as a biotic process but one may find it also used to describe an abiotic process‚ e.g.‚ due to weathering.) The decomposing organisms may use the release of elements for nutrients and by breaking apart the carbon-carbon bonds in organic matter this can release energy for them. These smaller molecules and nutrient elements

BALANCE OF TRADE AND BALANCE OF PAYMENTS – An Introduction The balance of payments account indicates a systematic record of all export incomes and import payments of a country during any year. Any import from abroad has to be paid for. On the other hand‚ any export will bring money flow into the country. If we subtract the total value of the imported commodities from the total value of the exported commodities of a country‚ what we obtain is called the ‘Balance of Trade’ of the country. If the

Base Details Siegfried Sassoon’s epic war poem "Base Details" focuses on a soldier’s bitterness toward the fact that old men wage war while young men fight it. Sassoon uses various literary devices to express his anger toward such injustice. The main ones being rhyme‚ strong connotative words and especially diction. The speaker‚ a soldier in World War I‚ contemplates what it would be like to be an officer in during war. By using a sarcastic and cynical tone‚ he is effectively able to condemn war

NUCLEIC ACIDS I.BASIC CONCEPTS II.CLASSES III.CHEMICAL NATURE IV.FUNCTION I.BASIC CONCEPTS NUCLEIC ACIDS polymeric macromolecules‚ or large biological molecules‚ essential for all known forms of life are made from monomers known as nucleotides Each nucleotide has three components: a 5-carbon sugar‚ a phosphate group‚ and a nitrogenous base If the sugar is deoxyribose‚ the polymer is DNA. If the sugar is ribose‚ the polymer is RNA. Together with proteins‚ nucleic acids are the most

DNA Worksheet Answer the following in at least 100 words: 1. Describe the structure of DNA. A molecule of DNA is made up of long chains of polymers and monomers called nucleotides. Those chains‚ two in particular that compose a strain of DNA‚ are formed by the grouping of nucleotides into polynucleotides. A nitrogenous base‚ a sugar‚ and a phosphate group make up the composition of a nucleotide. In the case of DNA‚ the four nucleotides that are found along the chain of DNA are thymine (T)

Separation of Amino Acids by Paper Chromatography Chromatography is a common technique for separating chemical substances. The prefix “chroma‚” which suggests “color‚” comes from the fact that some of the earliest applications of chromatography were to separate components of the green pigment‚ chlorophyll. You may have already used this method to separate the colored components in ink. In this experiment you will use chromatography to separate and identify amino acids‚ the building blocks of proteins

Lab 11: Animal Behavior Introduction Ethology is the study of animal behavior. There are two specific categories of behavior: learned ad innate. Orientation behaviors place the animal in their specific environment. Animals move away from sensory input in taxis where as behavior is the response to sensory input. Stimulus’ of light‚ heat‚ moisture‚ sound‚ or chemicals are mostly found in taxis. Kinesis is the movement that does not result in orientation with stimulus. When animals respond to each
