Uptake of these protons provides the energy for lactose transport and accumulation. PTS-regulatory domain (PRD). A protein domain of ∼100 amino acids that is found in many transcription regulators and that is always present in duplicate in PRD-containing regulators. These domains can be ...
HintThe atomic number of C is 6 and hence have 6 protons, 6 electrons and 6 neutrons. The C...
the more acidic is the measured pH.7Basic pH of carbon black with low oxygen content can be ascribed to the presence of basic surface oxides, although the π electron system of the basal planes of carbon was also shown to be sufficiently basic to bind protons from aqueous solutions of ...
It has 6 protons, 6 neutrons and obviously 6 electrons. A carbon atom is considered to be special and unique because it can bond with other carbon atoms to an almost unlimited degree. It is because its atom is very small in size and can conveniently fit in as a part of larger ...
In the middle is its main stable isotope (13C) made up of 6 protons (blue and 7 neutrons (yellow). On the right is the unstable radioactive form (14C) with 6 protons (blue) and 8 neutrons (yellow). During photosynthesis, the lighter, main form of carbon, 12C, is enriched. When ...

The extension of spectral region from 5.4 to 3.8 ppm shows the resonances of the H1 protons of glycogen (H1gly), β-(1,3)-glucan backbone (H1BB), and H1 (H1SC) and H6 (H6SC) protons of β-(1,6)-glucan side chains Full size image The isolation procedure used allowed obtaining β...
Without contact between them how could one of them sense whether the others had combined with oxygen? And how could as heterogeneous a collection of chemical agents as protons, chloride ions, carbon dioxide, and diphosphoglycerate influence the oxygen equilibrium curve in a similar way? It did ...
They have the same number of protons but differ in the number of neutrons in their nuclei. Therefore, they differ in atomic mass number. Nevertheless, they display almost identical chemical properties. Carbon isotopes that occur naturally include Carbon-12, Carbon-13, and Carbon-14. Carbon-12 ...
Carbon is a special element in that it is able to form so many different and complex molecules. It is important in forming complicated molecules because of it's atomic structure. Answer and Explanation: Carbon is a small atom with only 6 protons and 6 electrons, so it is able to fit in...
