It’s quite interesting to note these days what we can eat and what we shouldn’t be eating. Even if the food product is actually edible, the metabolites may not be regarded as safe. We know a few things about what not to consume in overly large quantities. Sugar, we know, isn&rsqu...

The paper establishes a chemical principle for designing integrin inhibitors that stabilize the inactive, closed conformation rather than the active, open conformation. Integrins are proteins involved in cell adhesion and signaling. Many integrins exist in equilibrium between inactive closed and ...

I’ve always had a strong interest in chemistry, and it has played a significant role in shaping both my academic and professional journey. As a data professional with a background in chemistry, I’ve found many ways to apply both my scientific and research skills like creativity, curiosit...

Order of Reaction The order of a reaction is the sum of the exponents α and β in the rate law expression. It indicates how many reactant molecules must collide in a single event for the reaction to occur. Temperature Dependence of Rate of Reaction The Arrhenius equation is a ...

Ionic bonding: This type of bond occurs when one atom transfers an electron to another atom. The atom that loses the electron becomes positively charged (cation), and the atom that gains the electron becomes negatively charged (anion). The oppositely charged ions attract each other, forming an ...

RDKit is an open-source cheminformatics toolkit written in C++ that can also be used in Java, Python, and KNIME. It provides a wide collection of cheminformatics functionality, such as reading and writing molecules, working with atoms, bonds and rings, generating 2D or 3D coordinates, sear...

Chemical elements are the basic building blocks of all matter. They are pure substances that cannot be broken down into simpler substances by chemical means. There are currently 118 known elements, each with its own unique set of properties. The most common way to represent chemical elements...

Why combine the brain, human emotions, and rodents in one study? For those who know a bit more about prairie voles, it’s quite obvious. Several years ago, scientists suggested in “Science” that prairie voles comfort individuals close to them in distress. This is thanks to oxytocin,...

Came across the ChemBERTa-77M-MTR at Hugging face looks like it's pre-trained on 77M molecules. ChemBERT is a large-scale pre-trained molecular transformer model based on the BERT architecture, specifically designed for tasks in chemistry, drug discovery, or materials science...

The paper establishes a chemical principle for designing integrin inhibitors that stabilize the inactive, closed conformation rather than the active, open conformation. Integrins are proteins involved in cell adhesion and signaling. Many integrins exist in equilibrium between inactive closed and ...

The answer is a bold yes, and there are a few ways that we can approach the problem. Mine might not be the fastest, but it is accurate for all chemical equations that do not include polyatomic decomposition. To elaborate on that caveat, a polyatomic on one side of the equation breaks apart...

What is Chemical Bonding? Definition: — Chemical bonding is the process by which atoms join together to form molecules or compounds. — Atoms are the tiny building blocks of matter, and bonding is like their way of holding hands to create something new. Read More &nbsp...

Like most people, all my high school science classrooms had one wall papered with a huge, multi-coloured chart. It was, of course, the Periodic Table of the Elements. Readers who were paying extra-close attention in their chemistry classes may remember that Dimitri Mendeleev came up with the peri...

The amount of matter in an object. Mass, a cornerstone concept that serves as a fundamental property that defines the quantity of matter in an object. Delving into the essence of mass unveils its pivotal role in shaping the behavior of objects in the physical world. At its core, mass represents the...

Chemical reaction like magic tricks happening all around us, turning things into something entirely different. When different things called (reactants) get together, they rearrange their tiny parts (atoms) to make new things (products). Let’s take a simple journey into...

When hydrogen in the core of a star is exhausted, the star begins to contract and heat up as a result. If the star’s mass is insufficient, it will simply shed its outer layers of material, leaving only a core consisting of helium (a helium white dwarf). Still, if the star’s mass is large...

Soon after the Universe appeared, the first atomic nuclei were formed, resulting in the Universe being filled with 90% hydrogen nuclei (protons) and 10% helium nuclei. Besides them, there was also a tiny amount of lithium, which did not exceed 0.00001% of all nuclei, while the content of heavier nuc...

I wanted to follow up some of the fantastic and less-than-fantastic posts above with a reminder that, while this is obviously an important and emotional issue, we’re all here discussing this because we want the same thing — to do the right thing as (volunteers) for the participants of ou...

Immediately post treatment my skin felt quite warm and a little itchy. I usually experience a histamine response to skin treatments, so I was ready to take an antihistamine post treatment. Under instruction from my dermal clinician, I will not get my face wet tonight or use any active ingredients on...

Here are a few personal experiences with chemical exfoliants or peeling solutions: Brighter and Smoother Skin: After incorporating a glycolic acid peel into my skincare routine, I noticed a significant improvement in the brightness and smoothness of my skin. The peel helped to remove dead skin...
