A plant extracellular polyester formed largely from oxygenated fatty-acid derivatives, contributing to the cuticular barrier.
The mixture of hydrophobic surface lipids, often including very-long-chain fatty-acid derivatives, that contributes to plant surface barriers.
A linkage isomer is one member of a set exhibiting linkage isomerism, such as the N-bound or O-bound form of a coordinated nitrite.
Linkage isomerization changes which atom of an ambidentate ligand is bound to a central atom. Its rate depends on a reaction barrier, whereas the final equilibrium depends on relative free energies.
A posterior limb-bud signalling region involved in anterior–posterior patterning. The fate of its labelled cells and the identities of adjacent anatomical digits are related but distinct observations.
A specialized distal ectodermal structure that supplies signals supporting limb outgrowth and patterning. Removing it simultaneously alters several processes, so truncation alone does not uniquely identify a timing mechanism.
Photoexcitation can dissociate a carbonyl ligand, creating a coordinatively unsaturated metal fragment. Capture by solvent or a tethered donor competes with CO recombination; net substitution therefore depends on both the photochemical step and subsequent trapping.
An ambidentate ligand has alternative donor atoms through which it can attach, producing different binding modes. Nitrite can bind through N or O; changing that attachment gives linkage isomerism.
A bridging ligand attaches to two or more metal centers. The symbol records bridging; its electron donation must be apportioned consistently between the metals in electron counting.
A sigma-donor ligand supplies an occupied orbital for sigma donation. Additional occupied or empty orbitals can make it a pi-donor ligand or a pi-acceptor ligand as well.
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!
Intro to OurBigBook
. Source. We have two killer features:
- 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-calculusArticles 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.

- to OurBigBook.com to get awesome multi-user features like topics and likes
- as HTML files to a static website, which you can host yourself for free on many external providers like GitHub Pages, and remain in full control
