and toxins from our bodies. Water also doesn’t have artificial sweeteners‚ dyes‚ or preservatives. It is natural and helps you maintain correct pH levels. The chemical reactions that take place in our body on a daily basis rely on water as well. Monomers of the organic compounds in the body use dehydration synthesis and hydrolysis to build and break down larger molecules. Each time this occurs they gain and lose water

Available online at www.sciencedirect.com Polyhydroxyalkanoates: bioplastics with a green agenda Tajalli Keshavarz and Ipsita Roy Production of polyhydroxyalkanoates (PHAs) has been investigated for more than eighty years but recently a number of factors including increase in the price of crude oil and public awareness of the environmental issues have become a notable driving force for extended research on biopolymers. The versatility of PHAs has made them good candidates for the study

ABSTRACT For many years‚ the use of natural polymers for the fabrication of packaging materials has been an interesting alternative to replace non-biodegradable polymers which are normal components of these materials. The core problem of these starch based plastics is their hydrophilic character and the fact that they tend to become brittle with ageing. Unmodified starch is too much hydrophilic to be used as food packaging material. Chemical modification must be carried out in order to make them

Proteins are polymeric chains that are built from monomers called amino acids. All structural and functional properties of proteins derive from the chemical properties of the polypeptide chain. There are four levels of protein structural organization: primary‚ secondary‚ tertiary‚ and quaternary. Primary structure is defined as the linear sequence of amino acids in a polypeptide chain. The secondary structure refers to certain regular geometric figures of the chain. Tertiary structure results from

Chapter 1 The Problem and Its Background Introduction Cigarette smoking is now becoming a big issue through out the world and especially in the Philippines. Because of this‚ the researcher finds it interesting to make a research paper about it. The researcher wants to know the cause and effect of cigarette smoking amongst her fellow student in the City University of Pasay. The researcher thinks that everyone knows the side effects that the cigarette is giving to its user but the hardest

contrast the functions of alpha amylase in the production of ethanol‚ with another commodity enzyme called Chymosin that is a protease and is used in the cheese industry. The production of ethanol requires the breakdown of starch from a polymer to a monomer such as glucose. The three general process steps‚ gelatinization‚ liquefaction and saccharification are used in converting starch to dextrose. Firstly starch granules found in nature are resistant to enzymic breakdown thus the process of gelatinization

Protein Misfolding Brittany Mascarenhas (ID: 20471654) Corey Nixon Biol 130 Tuesday October 23‚ 2012 In an organism‚ almost every dynamic function relies on proteins. A protein ’s function is a direct result of their intricate folding‚ the simplest level of which is the sequence of amino acids. (Fitzpatrick et al‚ 2011). Each amino acid has a unique characteristic because of the physical and chemical properties in their side chains‚ which affects the function of a protein
