Arabinose is included in the Cellular Zoomer as a urinary organic acid that reflects microbial carbohydrate fermentation and aspects of carbohydrate handling. When combined with other microbial metabolites, energy cycle markers, and oxidative stress data, arabinose helps clinicians map microbial‑host interactions and refine personalized strategies for restoring metabolic balance.

L (+)-Arabinose, an aldopentose monosaccharide, is an isomer of D-galactose, commonly used as a substrate in bacterial growth media for the growth of arabinose-utilizing bacteria. It enters the bacterial cell through the phosphoenolpyruvate-dependent phosphotransferase system. Microorganisms can only ferment specific carbohydrates, depending on the enzymes they possess to break down ...

D-(?)-Arabinose | Suitable for gas chromatography (GC) | D-(?)-Arabinose is a D-ribose analogue present in sugar polymers such as the arabinogalatans of mycobacterial cell walls and plant tissues | D-Arabinose is a reducing sugar | Buy carbohydrates online from Sigma Aldrich
L-Arabinose is used as a substrate to identify, differentiate and characterize pentose sugar isomerase (s). L-Arabinose is used in the bioproduction of L-ribose.
L-Arabinose is the naturally occurring isomer and is a constituent of plant polysaccharides. Most bacteria contain an inducible arabinose operon that codes for a series of enzymes and transporters that allows L-arabinose to be used as the sole carbon source in microbial culture.

L-arabinose operon is composed of structural genes and regulatory regions including the operator region (araO1, araO2) and the initiator region (araI1, araI2). [7] The structural genes, araB, araA and araD, encode enzymes for L-arabinose catabolism. There is also a CAP binding site where CAP-cAMP complex binds to and facilitates catabolite repression, and results in positive regulation of ...
L- (+)-Arabinose, a five-carbon sugar found widely in nature, plays a pivotal role in biochemical research, particularly in microbiology and biomedicine. In microbial culture, it serves as a sole carbon source for various bacteria, as many bacteria contain an inducible arabinose operon, allowing them to utilize L-arabinose as a primary carbon source. This characteristic has made arabinose ...

Arabinos är en aldopentos - en monosackarid - som innehåller fem kolatomer och en aldehyd (CHO)funktionell grupp. Av biosyntetiska skäl är de flesta sackarider nästan alltid rikligare i naturen som "D"-formen, eller strukturellt analog med D- glyceraldehyd. (D/L-nomenklaturen hänvisar inte till molekylens optiska rotationsegenskaper utan till dess strukturella analogi med ...

Arabinose Operon Arabinose is a 5 carbon sugar that can be used as an alternative carbon and energy source by the bacteria Escherichia coli. The enzymes necessary for the metabolism of this sugar are encoded by the araBAD operon. The operon encodes a single polycistronic mRNA with three open reading frames. Each open reading frame encodes one of the enzymes of the catabolic pathway for ...

Arabinose The aldopentose monosaccharide arabinose is one of the most abundant sugars in lignocellulosic hydrolyzates derived from agricultural or forestry production. In bacteria, arabinose typically enters the pentose phosphate pathway as xylulose-5-phosphate, following a three-step enzymatic conversion process: in the first step, arabinose isomerase (AraA) converts arabinose to ribulose ...

L-Arabinose is an arabinose isomer widely found in nature, while D-arabinose is less common. L-Arabinose is a constituent of many biopolymers that make up plant cell walls.

The L-arabinose operon, also called ara operon, encodes enzymes needed for the catabolism of arabinose to xylulose 5-phosphate.
The arabinose operon in Escherichia coli is essential for the catabolism of the sugar L-arabinose, consisting of structural genes (araA, araB, and araD) and regulatory elements that control gene expression. This operon is regulated both positively, in the presence of arabinose and absence of glucose, and negatively, when arabinose is absent, leading to repression of transcription. Mutations in ...
L-Arabinose is a crucial sugar in plant metabolism, playing a role in cell wall flexibility and abiotic stress tolerance.
