The list of biophysically important macromolecular crystal structures typically includes a variety of key biomolecules, such as proteins, nucleic acids, and their complexes, that have been structurally characterized through X-ray crystallography or other crystallographic methods. Here are some categories and examples of such structures that are often regarded as significant in biophysics and structural biology: ### Proteins 1.
Hydrophobicity scales are numerical or graphical representations that quantify the hydrophobic (water-repelling) or hydrophilic (water-attracting) nature of amino acids or other molecules. These scales are valuable in biochemistry and molecular biology for understanding protein folding, interactions, and the behavior of biomolecules in aqueous environments. ### Key Points about Hydrophobicity Scales: 1. **Hydrophobicity Measurement**: The scales measure the tendency of a substance or amino acid to interact with water.
Histone by Ciro Santilli 37 Updated +Created
These are apparenty an important part of transcriptional regulation given the number of modifications they can undergo! Quite exciting.
The Journal of Cellular Plastics is a scientific publication that focuses on research and development related to cellular plastics, which are a category of materials characterized by their cellular structure and lightweight properties. These materials often exhibit beneficial qualities such as low density, thermal insulation, and sound absorption, making them useful in various applications including packaging, construction, automotive, and aerospace industries.
The Index of Biophysics Articles typically refers to a curated list or database that catalogs articles related to biophysics. Biophysics is an interdisciplinary field that applies the principles and methods of physics to understand biological systems. An index might include various types of articles, such as research papers, reviews, and case studies, and could be organized by topics like molecular biophysics, cellular biophysics, or computational biophysics.
Isothermal titration calorimetry (ITC) is a sensitive and versatile technique used to measure the thermodynamics of molecular interactions, such as binding affinities, reaction kinetics, and the enthalpic and entropic changes associated with these processes. It provides real-time, quantitative data on the heat change that occurs during a chemical reaction or physical interaction, typically between a ligand and a macromolecule (like a protein, nucleic acid, or polymer).
"Atom" is not a specific book by Isaac Asimov, but it may refer to his extensive writings on science, particularly in the field of atomic physics and chemistry. Asimov, a prolific science fiction author and science popularizer, wrote numerous essays and books that explore the principles of atomic theory, nuclear reactions, and the societal implications of atomic energy.

Magnetoreception by Wikipedia Bot 0
Magnetoreception is the ability of certain animals to detect and respond to the Earth's magnetic field. This sense allows them to navigate and orient themselves in their environment, which is particularly useful for migration and long-distance travel. Many species exhibit magnetoreception, including birds, turtles, salmon, and even some mammals. The mechanisms underlying this ability are not entirely understood, but research suggests that it may involve several biological processes.
Microbial electrochemical technologies (MET) are a set of processes that leverage the activities of microorganisms to convert chemical energy from organic or inorganic compounds into electrical energy or to drive chemical reactions. These technologies primarily focus on the interactions between microbes and electrodes in electrochemical systems. Here are some key components and applications of MET: ### Key Components 1. **Microbial Fuel Cells (MFCs)**: These devices convert the biochemical energy from microbial metabolism directly into electricity.

Nanophysiology by Wikipedia Bot 0
Nanophysiology is an interdisciplinary field that combines principles from nanotechnology and physiology to study the interactions between nanoscale materials and biological systems. It involves the examination of how nanoscale structures, such as nanoparticles or nanomaterials, affect cellular and physiological processes. Key areas of focus in nanophysiology include: 1. **Cellular Interactions**: Understanding how nanoparticles interact with cells, including their uptake, distribution, and potential cytotoxic effects.
B Reactor by Ciro Santilli 37 Updated +Created
Reactor of the Hanford site of the produced the plutonium used for Trinity and Fat Man.
This was the first full scale nuclear reactor in the world, and was brought up slowly to test it out.

Fibbinary number by Wikipedia Bot 0
A Fibbinary number is defined as a binary number that does not contain any consecutive ones. Essentially, it is a binary representation where the digit "1" can appear, but never two "1s" in adjacent positions. In this context, the term "Fibbinary" is derived from the Fibonacci sequence, as it relates to the concept of Zeckendorf's theorem.

Pinned article: ourbigbook/introduction-to-the-ourbigbook-project

Welcome to the OurBigBook Project! Our goal is to create the perfect publishing platform for STEM subjects, and get university-level students to write the best free STEM tutorials ever.
Everyone is welcome to create an account and play with the site: ourbigbook.com/go/register. We belive that students themselves can write amazing tutorials, but teachers are welcome too. You can write about anything you want, it doesn't have to be STEM or even educational. Silly test content is very welcome and you won't be penalized in any way. Just keep it legal!
We have two killer features:
  1. topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculus
    Articles of different users are sorted by upvote within each article page. This feature is a bit like:
    • a Wikipedia where each user can have their own version of each article
    • a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
    This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.

  2. local editing: you can store all your personal knowledge base content locally in a plaintext markup format that can be edited locally and published either:
    This way you can be sure that even if OurBigBook.com were to go down one day (which we have no plans to do as it is quite cheap to host!), your content will still be perfectly readable as a static site.
    Figure 5. . You can also edit articles on the Web editor without installing anything locally.
