Description
L(+)-Arabinose, also known as L-arabinose or L-arabinopyranose, is a monosaccharide and a pentose sugar with the chemical formula C5H10O5. It is a naturally occurring sugar found in a wide range of plants and is an important component of hemicellulose and pectin, which are critical biopolymers in the cell walls of plants. L(+)-Arabinose is a white to off-white crystalline powder and has a sweet taste.
Uses
Used in Biochemical Research:
L(+)-Arabinose is used as a biochemical research tool for identifying, differentiating, and characterizing pentose sugar isomerase, an enzyme that catalyzes the interconversion of pentose sugars.
Used in Microbial Culture:
L(+)-Arabinose serves as a carbon source in microbial culture, providing an essential nutrient for the growth and metabolism of certain microorganisms.
Used in Bioproduction:
L(+)-Arabinose is involved in the bioproduction of L-ribose, an important sugar molecule that plays a crucial role in various biological processes, including the synthesis of nucleic acids and energy metabolism.
Used in Flavor Production:
L(+)-Arabinose finds application in the production of savory reaction flavors, which are used to enhance the taste and aroma of various food products.
Used in Antiviral Drug Development:
The derivatives of L(+)-Arabinose are used in the development of antiviral agents, such as nucleoside analogs, which can inhibit viral replication and treat viral infections.
Used in Plant Biopolymer Composition:
As a base component of hemicellulose and pectin, L(+)-Arabinose plays a critical role in the structure and function of plant cell walls, contributing to their mechanical strength and defense against pathogens.
Purification Methods
beta-L-(+)-Arabinose is recrystallised slowly, twice, from 80% aqueous EtOH, then dried under vacuum over P2O5. It can also be purified by heating the arabinose (200g) with glacial acetic acid (300mL) on a boiling water bath for 45minutes, cooling, filtering, washing with 95% EtOH (500mL) in four portions and drying at 56-60o over P2O5. It has been recrystallised from 5times its weight of 76% EtOH using charcoal (10g) to yield 127g, m 155-157o, [] 20D +190.6o and mutarotating to +104o (c 4, H2O).

Check Digit Verification of cas no
The CAS Registry Mumber 87-72-9 includes 5 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 2 digits, 8 and 7 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 87-72:
(4*8)+(3*7)+(2*7)+(1*2)=69
69 % 10 = 9
So 87-72-9 is a valid CAS Registry Number.

As part of our continuing study of apoptosis-inducing saponins from Cameroonian Albizia genus, one new triterpenoid saponin, named adianthifolioside J (1), together with the known gummiferaoside E (2), were isolated from Albizia adianthifolia stems. The s

The methanol extract from the leaves of Ilex paraguariensis A. St.-Hil. (Aquifoliaceae), popularly known as mate, maté, or yerba maté, inhibits the intracellular triglyceride accumulation in HepG2 cells and suppresses the plasma triglyceride elevation in olive oil-treated mice. Three new triterpene saponins, termed mateosides I (1), II (2), and III (3), were isolated from the extract along with 29 known compounds. The structures of 1–3 were elucidated based on chemical and spectroscopic evidence. Among the isolates, principal saponin constituents, 2 and matesaponins 1 (7) and 2 (9), potently inhibited the triglyceride accumulation in HepG2 cells simultaneously treated with oleic acid and high glucose. In vivo assay of the methanol extract of I. paraguariensis revealed that 7 and 9 showed anti-hyperlipidemic activities in olive oil-treated mice. These results suggested that the saponin constituents of I. paraguariensis could be valuable bioactive marker for the anti-obesogenic activity.

From the ethanol extract of Glinus oppositifolius, collected at Phu Yen province, Viet Nam, one new triterpenoid saponin (1) and four known compounds (2–5) were isolated. By means of NMR and HR-ESI-MS analyses, their structure was elucidated as 3-O-(β-D-xylopyranosyl-(1→3)-β-D-xylopyranosyl)spergulagenin A or glinusopposide V (1), glinusopposide L (2), spergulin B (3), vitexin (4) and astralagin (5). Two compounds (1–2) showed weak inhibitory activity against α-glucosidase.
