- By expanding the scope of sustainability to the entire lifecycle of chemical products, the concept of circular chemistry aims to replace today’s linear ‘take–make–dispose’ approach with circular processes. This will optimize resource efficiency across chemical value chains and enable a closed-loop, waste-free chemical industry.

Apr 16, 2022 · Circular Dichroism, an absorption spectroscopy, uses circularly polarized light to investigate structural aspects of optically active chiral media. It is mostly used to study biological molecules, their structure, and interactions with metals and other molecules.
Circular dichroism (CD) is dichroism involving circularly polarized light, i.e., the differential absorption of left- and right-handed light. [1][2] Left-hand circular (LHC) and right-hand circular (RHC) polarized light represent two possible spin angular momentum states for a photon, and so circular dichroism is also referred to as dichroism fo...

Circular dichroism (CD) is a type of spectroscopy that can tell you the type and percentage of secondary structure units in a proteinsample. After a successful CD experiment, you’ll have the answer to these questions: 1. Is my protein sample folded? 2. What percentages of alpha-helix, beta-sheet, and random coil are in my protein sample? And becaus...
Still not sold? At first glance, the above four questions probably sound easy to answer by other methods that are already in your repertoire. Consider the following case, however: “I work on the novel protease ____. I have purified a recombinant version of ____ and got a band on SDS-PAGE. My gel filtration chromatogram looks dodgy, though, and is f...
Before we dive into the technical aspects of CD theory, let’s present a quick summary of its pros and cons so you can decide whether CD really is for you (Table 1). Table 1. The pros and cons of circular dichroism.
I hate to break it to you, but CD theory is fundamentally biophysics. It relies on the unusual concept of circularly polarized light and can be a bit hard to wrap your head around. Essentially, it exploits the unequal absorption of clockwise and anticlockwise circularly polarized light by chiral protein molecules to answer the questions posed above...

Jan 23, 2023 · Circular Dichroism. Another property of chiral molecules is called circular dichroism (CD). This pertains to their differential absorption of left and right circularly polarized light.
Feb 25, 2022 · Circular dichroism spectroscopy is generally used to determine the secondary and tertiary structure of proteins. Its principle is based on differential absorption of left- and right-handed polarized light.
Jun 7, 2024 · A crystal structure is a distinctive arrangement of atoms, molecules, or ions in a crystal. It is highly ordered and repetitive, creating a characteristic pattern that defines the crystal’s shape and properties. The Role of Unit Cell in Crystal Structure. A fundamental idea in crystal structures is the unit cell.
