Proteins are organic compounds made of amino acids arranged in a linear chain and folded into a globular form. The amino acids in a polymer are joined together by the peptide bonds between the carboxyl and amino groups of adjacent amino acid residues. The sequence of amino acids in a protein is defined by the sequence of a gene, which is encoded in the genetic code.

Basic Rules of Protein Folding
31 Dec 2008 | | Contributor(s):: Seth Lichter
How are proteins made? Inside cells, messenger RNA first instructs the ribosomes as to the order which amino acids should be joined together. Linked together and released from the ribosome, the protein is not functional. It now needs to fold into a precise three-dimensional shape. There are no...
Bio-nanotechnology: Implications for More Effective Tissue Engineering Materials
06 Mar 2003 |
Nanotechnology can be defined as using materials and systems whose structures and components exhibit novel and significantly changed properties by gaining control of structures at the atomic, molecular, and supramolecular levels. Although many advanced properties for materials with constituent...

Bionanotechnology: a different perspective
30 Apr 2008 | | Contributor(s):: Murali Sastry
The study of the synthesis, exotic properties, assembly/packaging and potential commercial application of nanomaterials is an extremely important topic of research that is expected to have far-reaching global impact. The focus of my talk will be on an emerging branch of nanotechnology that...
Carbon Dioxide Gating in Silk Cocoon
21 Aug 2012 | | Contributor(s):: sunil kumar meena
Silk is the generic name given to the fibrous proteins spun by a number of arthropods. During metamorphosis, the larva of the silk producing arthropods excrete silk-fiber from its mouth and spun it around the body to form a protective structure called cocoon. An adult moth emerges out from the...
Cataract, Myopathy and Keratitis: Possible use of Nanoparticles
16 Sep 2008 | | Contributor(s):: Ch. Mohan Rao
Small heat shock proteins are critical for several cellular functions. Failure of heat shock proteins, thus, can cause compromised cellular activity leading to disease. Fungal Keratitis is an eye dieses that can be treated with anti fungal drugs. Availability of the drug at the site of action is...
Combining New Experimental and Informatic Tools for Protein Investigation and Engineering
09 Jan 2008 | | Contributor(s):: Alan Friedman
The stability and activity of proteins is dependent on both the correct functioning and placement of individual amino acids and their interactions. Great attention has been paid to critical individual residues (generally revealed by their location in the active site and their conservation among...
Computational Nanoscience, Lecture 27: Simulating Water and Examples in Computational Biology
16 May 2008 | | Contributor(s):: Elif Ertekin, Jeffrey C Grossman
In this lecture, we describe the challenges in simulating water and introduce both explicit and implicit approaches. We also briefly describe protein structure, the Levinthal paradox, and simulations of proteins and protein structure using First Principles approaches and Monte Carlo...
Computer Simulation of Nanoparticles, Viruses, and Electrical Power-Generating Bacteria
20 Mar 2007 |
Models of cells and nanometer-scale biosystems are presented that clarify their physico-chemical characteristics and allow for computer- aided design of therapeutic and nanotechnical devices. Multiscale techniques are used to obtain rigorous, coarse-grained equations for the migration and...

Exploiting the Electronic Properties of Protiens: An Approach to Nanoscale Electronics
From Research to Learning in Chemistry through Visualization and Computation
17 May 2007 | | Contributor(s):: Eric Jakobsson
Modern chemistry research and high school chemistry education are separated by institutional and geographical boundaries. As such, much of secondary chemistry education is still based on the periodic table instead of the computational methods that drive current chemistry research. In this talk,...
