MAs of macromolecules are held in their defined forms by non-covalent intermolecular interactions (rather than covalent bonds), and can be in either non-repeating structures (e.g., as in the ribosome (image) and cell membrane architectures), or in repeating linear, circular, spiral, or other patterns (e.g., as in actin filaments and the ...
fails in the case of certain macromolecules for which the properties may be critically dependent on fine details of the molecular structure. 2. If a part or the whole of the molecule fits into this definition, it may be described as either macromolecular or polymeric, or by polymer used adjectivally. [4]
Jmol is an open-source Java-based viewer for browsing molecular structures on the web; it includes a simplified "cartoon" version of ribbons. Other graphics programs such as DeepView (example: urease) and MolMol (example: SH2 domain) also produce ribbon images. KiNG [11] is the Java-based successor to Mage (examples: α-hemolysin top view and ...

Polymer degradation is a change in the properties—tensile strength, color, shape, or molecular weight—of a polymer or polymer-based product under the influence of one or more environmental factors, such as heat, light, and the presence of certain chemicals, oxygen, and enzymes.
AFM image of 1,5,9-trioxo-13-azatriangulene and its chemical structure. [3] A molecule is a group of two or more atoms that are held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions that satisfy this criterion.
The start codon in all mRNA molecules has the sequence AUG. The stop codon is one of UAA, UAG, or UGA; since there are no tRNA molecules that recognize these codons, the ribosome recognizes that translation is complete. [4] When a ribosome finishes reading an mRNA molecule, the two subunits separate and are usually broken up but can be reused.
The molecule shown is proline. The model shown to the left represents a ball-and-stick model of proline. The balls have colours: black represents carbon (C); red, oxygen (O); blue, nitrogen (N); and white, hydrogen (H). Each ball is drilled with as many holes as its conventional valence (C: 4; N: 3; O: 2; H: 1) directed towards the vertices of ...
