An alpha-helix with hydrogen bonds (yellow dots) The α-helix is the most abundant type of secondary structure in proteins. The α-helix has 3.6 amino acids per turn with an H-bond formed between every fourth residue; the average length is 10 amino acids (3 turns) or 10 Å but varies from 5 to 40 (1.5 to 11 turns).
It is a "chemistry aware" computer programming language with over 1,000 specific functions for analyzing and manipulating chemical structures and related molecular objects. SVL is a concise, high-level language whose programs are typically 10 times smaller than their equivalent when compared to C or Fortran .
The chemical bonds that make up the structure of members of each family are mixed ionic/covalent bonds, covalent bonds, and metallic bonds, respectively. ZIF glasses, on the other hand, are an organic-inorganic coordinated glass discovered only recently, and have a completely different structure than the three traditional glass families.
Laboratory Virtual Instrument Engineering Workbench (LabVIEW) [1]: 3 is a graphical system design and development platform produced and distributed by National Instruments, based on a programming environment that uses a visual programming language. It is widely used for data acquisition, instrument control, and industrial automation. It ...
While Modelica resembles object-oriented programming languages, such as C++ or Java, it differs in two important respects. First, Modelica is a modeling language rather than a conventional programming language. Modelica classes are not compiled in the usual sense, but they are translated into objects which are then exercised by a simulation engine.
This wavefunction describes the bonding in H 2 as the ionic interaction between an H + and an H-. Since none of these wavefunctions, Φ HL (covalent bonding) or Φ I (ionic bonding) perfectly approximates the wavefunction, a combination of these two can be used to describe the total wavefunction
Scaffold (programming) – Code generation technique or a project generation technique; Snippet (programming) – Small region of re-usable source code, machine code, or text; Template processor – Software designed to combine templates with a data model to produce result documents; Web template system – System in web publishing
The E and C parameters refer, respectively, to the electrostatic and covalent contributions to the strength of the bonds that the acid and base will form. The equation is -ΔH = E A E B + C A C B + W. The W term represents a constant energy contribution for acid–base reaction such as the cleavage of a dimeric acid or base.
