Biophysical chemistry is a relatively new branch of chemistry that covers a broad spectrum of research activities involving Systems biology biological systems . The most common feature of the research in this subject is to seek explanation of the various phenomena in biological systems in terms of either the molecules that make up the system or the Supramolecular chemistry supra molecular structure of these systems. Biophysical chemists employ various techniques used in physical chemistry to probe the structure of biological systems. These techniques include spectroscopic methods like nuclear magnetic resonance NMR and X ray diffraction . For example, the work for which Nobel Prize was awarded in 2009 to three chemists was based on x ray diffraction studies of ribosomes ref http nobelprize.org nobel prizes chemistry laureates 2009 press.html ref . Some of the areas in which biophysical chemists engage themselves are protein structure and the functional structure of cell membranes . For example, enzyme action can be explained in terms of the shape of a pocket in the protein molecule that matches the shape of the Substrate biochemistry substrate molecule or its modification due to binding ... compositions and sizes.

Unreferenced date January 2007 In chemistry , antagonism is a phenomenon where two or more agents in combination have an overall effect which is less than the sum of their individual effects. The word is most commonly used in this context in biochemistry and toxicology . Interference in the physiological action of a chemical substance by another having a similar structure. For instance, a receptor antagonist is an agent that reduces the response that a Ligand biochemistry ligand produces when it binds to a Receptor biochemistry receptor on a cell biology cell . An example of this is the interleukin 1 receptor antagonist. The opposite of antagonism is synergy . It is an negative type of synergism.

In chemistry , residue refers to the material remaining after a distillation or an evaporation, or to a portion of a larger molecule, such as a methyl group . It may also refer to the undesired byproducts of a reaction. In biochemistry and molecular biology , a residue refers to a specific monomer within the polymer polymeric chain of a polysaccharide , protein or nucleic acid . For example, one might say, This protein consists of 118 amino acid residues or The histidine residue is considered to be basic due to its imidazole ring. Note that a residue is different from a Functional group moiety , which, in the above example would be constituted by the imidazole ring or the imidazole moiety . Note the origin of this usage during the process by which monomer ic building blocks e.g. amino acid s are strung together into a polymeric chain e.g. a protein , some material typically adding up to one molecule of water is discarded from each building block, and only a residue of the building block ends up in the finished product. For example, a residue is an individual amino acid in a peptide chain. Interlang Category Distillation Chemistry stub de R ckstand Chemie nl Residu chemie ja zh ... more details

About syneresis in chemistry synaeresis in linguistics synaeresis Syneresis also spelled syn resis or synaeresis , in chemistry, is the solvent extraction extraction or expulsion of a liquid from a gel , as when lymph drains from a contracting clot of blood . Another example of syneresis is the collection of whey on the surface of yogurt . Syneresis can also be observed when the amount of diluent in a swollen polymer exceeds the solubility limit as the temperature changes. A household example of this is the counter intuitive expulsion of water from dry gelatin when the temperature increases. Syneresis has also been proposed as the mechanism of formation of the Silicon dioxide amorphous silicate composing the frustule of diatom s ref name diatom skeleton Cite journal doi 10.1002 bies.20731 issn 1521 1878 volume 30 issue 4 pages 328 37 last Grachev first Mikhail A coauthors Vadim V Annenkov, Yelena V Likhoshway title Silicon nanotechnologies of pigmented heterokonts journal BioEssays News and Reviews in Molecular, Cellular and Developmental Biology accessdate 2009 02 03 date 2008 04 url http www.ncbi.nlm.nih.gov pubmed 18348175 pmid 18348175 ref In the processing of dairy milk , for example during cheese making , syneresis is the formation of the curd due to the sudden removal of the hydrophilic peptides macropeptides , which causes an imbalance in intermolecular forces. Bonds between hydrophobic sites start to develop and are enforced by calcium bonds which form as the water molecules in the micelles start to leave the structure. This process is usually referred to as the phase of coagulation and syneresis. The splitting of the bond between residues 105 and 106 in the casein &kappa casein molecule is often called the primary phase of the rennet action, while the phase of coagulation and syneresis is referred to as the secondary phase.
