Functionals linear in curvature and protein folding

چکیده
The free energy of globular protein chain is considered to be a functional defined on smooth curves in three dimensional Euclidean space. From the requirement of geometrical invariance, together with basic facts on conformation of helical proteins and dynamical characteristics of the protein chains, we are able to determine, in a unique way, the exact form of the free energy functional. Namely, the free energy density should be a linear function of the curvature of curves E-mail: [email protected]; fax: +39089965275 E-mail: [email protected] E-mail: [email protected]

One of the most common procedures for exporting and warehousing handmade carpets is keeping them folded over one another. Handmade carpets come out of their stable states by being folded,while increasing storage time can cause serious and sometimes irreversible changes to them. In this research, a pilot model carpet has kept folded under a load equal to 50 g/cm2 and then the applied load increa...

متن کاملAlmost multiplicative linear functionals and approximate spectrum
We define a new type of spectrum, called δ-approximate spectrum, of an element a in a complex unital Banach algebra A and show that the δ-approximate spectrum σ_δ (a) of a is compact. The relation between the δ-approximate spectrum and the usual spectrum is investigated. Also an analogue of the classical Gleason-Kahane-Zelazko theorem is established: For each ε>0, there is δ>0 such that if ϕ is...
متن کاملProtein Stability, Folding, Disaggregation and Etiology of Conformational Malfunctions
Estimation of protein stability is important for many reasons: first providing an understanding of the basic thermodynamics of the process of folding, protein engineering, and protein stability plays important role in biotechnology especially in food and protein drug design. Today, proteins are used in many branches, including industrial processes, pharmaceutical industry, and medical fields. A...
متن کاملOsmolyte-Induced Folding and Stability of Proteins: Concepts and Characterization
It is well-known that the typical protein’s three-dimensional structure is relatively unstable in harsh conditions. A practical approach to maintain the folded state and thus improve the stability and activity of proteins in unusual circumstances is to directly apply stabilizing substances such as osmolytes to the protein-containing solutions. Osmolytes as natural occurring organic molecules ty...
