The peptidoglycan layer within the bacterial cell wall is a crystal lattice structure formed from linear chains of two alternating amino sugars, namely N-acetylglucosamine (GlcNAc or NAG) and N-acetylmuramic acid (MurNAc or NAM). The alternating sugars are connected by a β-(1,4)-glycosidic bond.
N-Acetylglutamic acid is an extracellular metabolite isolated from the prokaryote Rhizobium trifolii that was characterized using many structure determination techniques such as proton nuclear magnetic resonance (1 H NMR) spectroscopy, Fourier-transform infrared spectroscopy, and gas chromatography-mass spectrometry.
The different types of lipid-linked oligosaccharide (LLO) precursor produced in different organisms.. N-linked glycosylation is the attachment of an oligosaccharide, a carbohydrate consisting of several sugar molecules, sometimes also referred to as glycan, to a nitrogen atom (the amide nitrogen of an asparagine (Asn) residue of a protein), in a process called N-glycosylation, studied in ...
N-Acetylmannosamine is a hexosamine monosaccharide.It is a neutral, stable naturally occurring compound. N-Acetylmannosamine is also known as N-Acetyl-D-mannosamine monohydrate, (which has the CAS Registry Number: 676347-48-1), N-Acetyl-D-mannosamine which can be abbreviated to ManNAc or, less commonly, NAM).
Enantioselective synthesis, also called asymmetric synthesis, [1] is a form of chemical synthesis.It is defined by IUPAC as "a chemical reaction (or reaction sequence) in which one or more new elements of chirality are formed in a substrate molecule and which produces the stereoisomeric (enantiomeric or diastereomeric) products in unequal amounts."
Nicotinamide adenine dinucleotide consists of two nucleosides joined by pyrophosphate.The nucleosides each contain a ribose ring, one with adenine attached to the first carbon atom (the 1' position) (adenosine diphosphate ribose) and the other with nicotinamide at this position.
Medicine: Organic synthesis plays a vital role in drug discovery, allowing chemists to develop and optimize new drugs by modifying organic molecules. [9] Additionally, the synthesis of metal complexes for medical imaging and cancer treatments is a key application of chemical synthesis, enabling advanced diagnostic and therapeutic techniques. [10]
N-acetyl-β-d-glucosaminidase (EC 3.2.1.30; EC 3.2.1.52) is a mesophilic hydrolase that specifically hydrolyzes N-acetyl-glucosides. The enzyme is found across a wide variety of marine and terrestrial creatures with the primary function of breaking down oligosaccharides in the presence of water.
