microESR for Undergraduate Labs

microESR is a small, portable research grade instrument that provides an excellent teaching tool for undergraduate chemists. This instrument enables classroom demonstrations of both simple topics such as free radicals in everyday life to far less intuitive subjects including electron density, spin-orbit coupling, spin-spin exchange, and forbidden transitions.

Raman Spectroscopy as a Universal Analytical Technique for Bodily Fluids

In this interview, Professor Igor K. Lednev discusses the potential of Raman spectroscopy to replace biochemical tests as a universal analytical technique for bodily fluids (biological stains) in forensic science. This interview conducted at Pittcon 2019.

Structure and Function of Proteoglycans

Proteoglycans are ubiquitous molecules that function as critical components of the extracellular matrix. These proteins are composed of glycosaminoglycan chains that are covalently attached to a protein core. Even though just a handful of proteins have the propensity to become proteoglycans, their range of functions and potential roles in organism development is extremely broad.

	Researchers publish review on serial femtosecond crystallography Researchers from the Moscow Institute of Physics and Technology have published a review on serial femtosecond crystallography, one of the most promising methods for analyzing the tertiary structure of proteins.

	Improving the Safety of Biotherapeutics: Tracing the Protease Inhibitor AEBSF with RPLC-UV Antibodies are highly selective agents that can be used to target a variety of cancers and pathogenic infections in humans. Antibody production is usually carried out using mammalian cell culture. However, during production, these cells produce proteases that degrade the antibodies, thus necessitating the use of protease inhibitors.

	Acetolactate Synthase Structure, Function, and Drug Development Acetolactate synthase can be found in plants, fungi, archaea, and bacteria, but not animals. This enzyme is involved in condensing two pyruvate molecules to form acetolactate, or pyruvate and 2-ketobutyrate. This leads to the formation of acetohydroxybutyrate (AHB). In the case of eubacteria, like E.coli or Salmonella typhimurium, three types of acetolactate synthase (AHAS) enzymes are present: AHAS I, AHAS II, AHAS III.

	Scientists delay aging using protein found in young mice The protein in question is an enzyme called extracellular nicotinamide phosphoribosyltransferase (eNAMPT), which catalyzes the production of nicotinamide adenine dinucleotide (NAD), a molecule found in every cell in the body. NAD is an essential part of the electron transfer chain in the mitochondria, the organelle responsible for producing energy in cells.

	Protein Complex Analysis Proteins, also called polypeptides, are the polymers of amino acids. There are a total of twenty amino acids called monomers that exist naturally in proteins. Proteins are found in abundance and are differentiated from each other according to the number, type, and arrangement of amino acids in series, which comprise the mainstay of polypeptides.
