Introduction Poly-c-glutamic acid (c-PGA) is an unusual anionic‚ naturally occurring homo-polyamide that is made of D and L -glutamic acid units connected by amide linkages between a-amino and c-carboxylic acid groups (Fig. 1). It was ®rst discovered by Ivnovics and co-workers a (Ivnovics and Bruckner‚ 1937; Ivnovics and Erds‚ a a o 1937) as a capsule of Bacillus anthracis which was released into

although other local senses are often affected as well. Also‚ when it is used on specific nerve pathways (nerve block)‚ paralysis (loss of muscle power) can be achieved as well. Clinical local anesthetics belong to one of two classes: * Amino amide local anesthetics‚ and * Amino ester local anesthetics. Synthetic local anesthetics are structurally related to cocaine. They differ from cocaine mainly in that they have no abuse potential and do not act on the sympathoadrenergic system‚ i

Acetaminophen Abstract: The aim of this experiment is to prepare Acetaminophen (p-acetamidophenol)‚ an amide. Acetaminophen will be created by treating an amine (p-aminophenol) with an acetic anhydride. Color impurities present in the solid acetaminophen will be removed and then the decolorized product will be collected on a Büchner funnel for further purification by crystallization. Purity will then be determined by melting point. Introduction: Acetaminophen is commonly used as an analgesic to

INTRODUCTION The purpose of this project paper is to highlight the chemistry and science of the very curious material: Kevlar®. Our aim is to create a very informative piece of writing that can be of reference to our project subject‚ when in need. Upon taking up this project we conducted some very superficial research initially. Our research led us to believe that Kevlar® is a rather well known material that has been used in bullet proof vests for the last couple of decades. In addition to
