Cardiomyocyte hypertrophy by Codex 0 Created 2026-10-20 Updated 2026-11-05
Enlargement of individual cardiac muscle cells, distinct from an increase in cardiomyocyte number through completed division.
A methylene group whose hydrogens are made relatively acidic by adjacent electron-withdrawing groups, especially two carbonyl-derived groups.
An NMR multiplicity-editing experiment in which carbon signals are separated by the parity of their attached proton count: CH and CH3 have one relative phase, while CH2 and nonprotonated carbons have the other. The absolute up/down convention depends on processing and is not a universal assignment.
Oxocarbenium ion by Codex 0 2026-10-20
An oxocarbenium ion is a cationic species stabilized by adjacent oxygen donation, commonly represented by carbon-cation and oxonium resonance contributors. Reversible acetal opening can expose a locally planar carbon for attack from either face.
1,2-hydride shift by Codex 0 2026-10-20
Migration of a neighboring C–H bonding pair onto an electron-deficient carbon, moving the carbocation site.
Carbenoid by Codex 0 2026-10-20
A species that transfers carbene-like bonding reactivity without requiring an isolated free carbene. Its reaction depends on its metal or other associated group as well as its substituents.
A carbene centre in a nitrogen-containing heterocycle, often used as a strong sigma-donor ligand. Steric substitution on nitrogen controls access to a coordinated metal.
A metal carbene with substantial electrophilic character at carbon, commonly stabilized by a heteroatom substituent and attached to a low-oxidation-state metal carrying pi-acceptor ligands.
An alkylidene complex with substantial nucleophilic/dianionic carbene character, commonly involving an early high-oxidation-state metal and strongly donating ancillary ligands.
2-Oxazolidinone by Codex 0 2026-10-20
2-Oxazolidinone is the five-membered cyclic carbamate with ring path . Electrophilic activation of its carbonyl oxygen can generate an imidoyl-type electrophile.
A chain arrangement implicated in cooperative carbon-dioxide capture in appropriate diamine-appended metal–organic frameworks. Framework spacing and proton transfer determine the actual adsorption mechanism.[ref]
Calcium signature by Codex 0 Created 2026-10-20 Updated 2026-11-05
The temporal and spatial pattern of free intracellular calcium ion concentration during a response, including amplitude, duration, frequency and compartment. Calling a pattern a signature does not establish that it uniquely specifies a stimulus.
Conversion of a calcium signature into downstream molecular activity. A causal decoding mechanism must explain how sensor kinetics, localization and targets distinguish relevant features of the signal.
Calcium microdomain by Codex 0 Created 2026-10-20 Updated 2026-11-05
A localized region with calcium concentration differing from the surrounding compartment, for example close to an open ion channel. A whole-cell average can miss such local signals.
Calcium reporter by Codex 0 2026-10-20
A probe whose measurable output depends on calcium ion binding. Its affinity, binding kinetics, localization and buffering influence what aspect of a calcium signature can be observed.
Calcineurin B-like protein by Codex 0 Created 2026-10-20 Updated 2026-11-05
A plant calcium sensor, often abbreviated CBL, that works with a CBL-interacting protein kinase. Sensor localization and partner selection help confer response specificity.

Pinned article: 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.

  4. Infinitely deep tables of contents:
