Campbell’s Biology‚ 9e (Reece et al.) Chapter 5 The Structure and Function of Large Biological Molecules In Chapter 5‚ the principles of chemistry covered in earlier chapters are applied to the understanding of biological polymers and lipid membranes. The emphasis is on properly linking monomers and their polymers‚ and on the structural and functional diversity of the different polymer types. Particular attention is given to protein structure‚ because this is central to understanding subsequent

Written Report: Prolonged Immobilization I. A. Definition Defined as prolonged inactivity‚ bed rest and immobilization were widely used in the early days of rehabilitative science in the management of trauma and acute and chronic illness‚ before the physiologic effects were well understood. It was generally assumed that rest fostered healing of the affected part of the body. However‚ while it has beneficial effects to soft tissue healing and to bone healing after fractures among a myriad of other

and understanding the enzyme. Stereospecificity is a property of a reaction mechanism that allows for a different stereoisomer reaction product from a different stereoisomeric reactant basically‚ the enzyme is able to act on a steric or optical isomer. Chemical specificity entails three components: Absolute specificity - the enzyme catalyzes with only one enzyme. Group specificity - the enzyme will act only on molecules that have specific functional groups. These are more common and such functional

Analysis of a Volatile Liquid Abstract: The purpose of this experiment was to use various methods of analysis to determine the identity of an unknown volatile liquid. In the first part of the experiment‚ the molecular mass was found by using water to find the volume of a flask through calculations and this as well as the mass of the gas of the unknown liquid were put into the a manipulated version of the ideal gas equation to determine the molar mass of the liquid‚ which was 14.21g per
