Starch is composed of α-amylose and amylopectin. The structure of α-amylose consists of long polymer chains of glucose units connected by an α (1-4) linkage. Amylopectin consists mainly of α (1-4) linked glucose residues but is a branched molecule with α (1-6) branch points every 24 to 30 glucose residues on average. As a result of the bond angles in the α (1-4) linkage‚ amylose actually forms a spiral much like a coiled spring. Amylose is responsible for the formation of a deep blue color in the presence

Purpose: This experiment is used to perform a series of synthesis reactions that convert aluminum foil to alum. Alum is used in cooking‚ to treat wastewater‚ and is used in common deodorant. In this lab a series of four reactions will occur to yield alum. Calculations: Aluminum foil: 0.5035 grams Alum & Watch Glass: 21.7691 grams Watch Glass: 15.1560 grams Alum: 6.6131 gram Theoretical Yield of Alum: 2Al(s) + 2KOH(aq) + 4H2SO4 + 22H20 -> 3H2(g) + 2KAl(SO4)2 + 12H2O(s) 0.5035gAl

Environment Week 1 Biomes and Diversity. As you have learned in the readings‚ extinction is a natural selection process. You have also read that humans are often responsible for accelerating this process. Using at least two scholarly sources‚ address whether or not we as humans should be concerned with the extinction rate. Additionally‚ discuss whether or not humans strive to preserve representative samples of all biomes on the planet Introduction to Science. Read Lab 1: Introduction to Science

The purpose of this lab that was completed was to observe standing wave patterns in clamped strings‚ and understand the effect of the standing wave frequencies of changing the length (L)‚ tension (T)‚ and linear density (p) of the strings. Standing wave patterns in strings are observed at certain excitation frequencies for special values of L‚ T‚ and p. A standing wave can be defined as a vibration of a system in which some particular points remain fixed while others between them vibrate with the

College General Biology I Enzymes‚ test for effect of pH on catalase activity Purpose The main purpose of this experiment was to learn about enzymes and how to test for the effect of pH on catalase activity and to be able to tell if a reaction is an exergonic or endergonic process. Introduction Enzymes are made from amino acids‚ which are made from proteins. In order to make an enzyme‚ hundreds of amino acids are strung together in a very specific and unique order and eventually is folded

1 What is the goal and purpose of a BIA? To identify the impact of outages. More specifically‚ the goal is to identify the critical functions that can affect the organization. 2 Why is a business impact analysis (BIA) an important first step in defining a business continuity plan (BCP)? The first step towards creating a serious BCP is to identify the potential disasters one by one and determining what the potential impact might be on your business. In order to generate a professional and

Section 1 Purpose: The purpose of this lab was to separate plant pigments using chromatography‚ calculate Rf values using the collected data‚ and study photosynthesis with isolated chloroplasts. Light energy Light energy Background Information (Activity A): In photosynthesis‚ plant cells convert light energy into chemical energy that is stored in sugars and other organic compounds. It is an endergonic and anaerobic reaction. Critical to the process is chlorophyll‚ the primary photosynthetic pigment
