Amino acids are composed of a central α-carbon, which is bonded to a hydrogen atom, an amino group (+NH3), a carboxyl group (COO−), and a distinct side chain (R) that confers specificity to each amino acid. The side chain groups are biologically important, and are classified by wh...
What Is an Atom? Atoms are often referred to as the building blocks of matter. Each element on the periodic table is composed of one type of atom and cannot be broken down into a simpler substance. Structure of the atom. (n.d.). Retrieved from http://www.nyu.edu/pages/mathmol/textb...
Each atom has a definite number of neutrons, protons, and electrons. The number of protons in the nucleus is called the atomic number, Z, and this number defines the chemical element that describes the atom. In a neutral atom, the number of electrons is equal to Z, and these orbit the...

The power of scattered electrons by an atom is negatively correlated with the energy of the incident electron13. Therefore, low-acceleration-voltage electrons produce more signal upon their interaction with the cryo-EM specimen. However, low-energy electrons create severer radiation damage14, allowing...
of 0.262 Å when aligning 862 backbone atoms. Similar to the arylalkylamineN-acetyltransferase model, the new structure is primarily composed of six α-helices and seven anti-parallel α-strands (Fig.1A). The AgmNAT structure displays a conserved GNAT fold, similar to that observed forD....
Key advantages of the Intel® In-Band Manageability solution are: Out-of-box cloud support: Azure* IoT Central and ThingsBoard.io. Single interface to handle OS, FW and Application (Docker container) updates. Scalable across Intel x86 (Intel® Atom® and Intel® Core®) architectures ...
(dashed red line), which is absent in the spectrum of Zn–Al LDH, Ni–Zn–Al LTH, and aqueous Zn solution. Such a shoulder is seen in previous studies, which suggests the central Zn atom is present in tetrahedral environment, surrounded by four oxygen atoms [27,54,55,56], ...
Ecb(min) is the minimum energy that a projectile of mass A1 and charge Z1 must have in order to overcome the Coulomb barrier of a target nucleus of mass A2 and charge Z2 in a central collision. For the reaction between an α-particle and the nucleus 14N, Ecb(min) has a value of...
