A crystal lattice is the structured, repeating organization in a crystal. There are different types of crystals: ionic, covalent, molecular, and metallic crystals. Any other form of solid is deemed an amorphous solid as the organization is completely random with no repeating pattern in the solid...
The structures suggest that the T-loops do not have a rigid structure and that they may be flexible in solution. The presence of a turn of 310 helix in the middle of the T-loop suggests that secondary structure could form when it interacts with soluble receptor enzymes. Co-crystals of G...
However, the plastic cups worked well this time. If your solution cools too quickly, impurities will not have a chance to fall out of the mixture, and crystals may look disorganized and irregular. Generally, crystals are quite uniform in shape. Check on the crystals regularly and make note ...
The size of a kidney stone is an important factor that determines the severity of the symptoms and the complications it may cause. Kidney stones are of different sizes. They range from small-sized crystals (small kidney stones) to large-sized stones (large kidney stones) such as the size of...

These structures reveal important information about the nature of the protein-DNA interaction, but a full understanding of the regulatory mechanism is currently hindered by the lack of structural information for the Fe–S cluster bound form. We report here the 1.95 Å resolution crystal structure ...
Two completely flexible random chains containing N atoms joined by links of length L can be superimposed by rigid-body motions to match their structures as closely as possible. The statistics of the root-mean-square best-fit distance D are discussed. For long chains, D2 tends of 0.125L2N. ...
The packing fraction of the crystal lattice can be determined by finding the volume of the atoms (spheres) and the volume of the cube. For this, we must known the number of the atoms present in the crystal lattice.Answe...
