25990-10-7 Usage

Uses

Different sources of media describe the Uses of 25990-10-7 differently. You can refer to the following data:
1. Polygalacturonic Acid is found in ripe fruits and some vegetables and is a degradation product of pectin in plants.
2. Polygalacturonic acid may be used to identify, differentiate and characterize plant cell wall degrading polygalacturonase(s) from fungi.

General Description

Polygalacturonic acid is composed of galacturonic acid unit arranged as a long polymer chain. Methyl esters of polygalacturonic acid forms pectin.

Biochem/physiol Actions

In land plants, polygalacturonic acids are major components of cell wall polysaccharides (pectins). Bound polygalacturonase-inhibiting peptides (PGIP) protect pectin from degradation by fungal polygalacturonases.

Check Digit Verification of cas no

The CAS Registry Mumber 25990-10-7 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,9,9 and 0 respectively; the second part has 2 digits, 1 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 25990-10:
(7*2)+(6*5)+(5*9)+(4*9)+(3*0)+(2*1)+(1*0)=127
127 % 10 = 7
So 25990-10-7 is a valid CAS Registry Number.

Colorimetric detection of glucose by a hybrid nanomaterial based on amplified peroxidase-like activity of ferrosoferric oxide modified with gold-platinum heterodimer

Bai, Zhenyu,Feng, Xiaoyang,Fu, Hao,Hu, Xueping,Li, Ping,Song, Xingliang

, p. 239 - 249 (2021/12/30)

The colorimetric detection of glucose using hybrid nanostructures is a rapidly growing research hotspot. In this work, we established a simple route for the synthesis of a class of multi-metal hybrid nanostructure materials and investigated their peroxidase-like performance for the colorimetric detection of glucose. The hybrid nanomaterial (Fe3O4@Au-Pt) incorporated ferrosoferric oxide nanoparticles (Fe3O4NPs) and heterodimers composed of gold (Au) and platinum (Pt), which presents excellent morphology and structure. On the basis of our research, we constructed an easy and sensitive colorimetric sensor for the detection of glucose and hydrogen peroxide (H2O2), and the results indicated that the Fe3O4@Au-Pt hybrid nanomaterial possessed preferable peroxidase-like activity in comparison with other nanozyme materials and showing prominent selectivity for glucose detection. For H2O2, the sensor has a linear range of 0.05-120 μM and a relatively low limit of detection (LOD) of 0.018 μM. For glucose, the linear range is 0.05-140 μM with an LOD of 0.025 μM. It is envisioned that these hydrophilic hybrid nanostructures will be widely applied in sensing target analytes, biomedical diagnosis, and therapeutic applications in the future by taking advantage of their specific structure and excellent catalytic performance.

Comparative study on the structural characterization and α-glucosidase inhibitory activity of polysaccharide fractions extracted from Sargassum fusiforme at different pH conditions

Jia, Rui-Bo,Li, Zhao-Rong,Lin, Lianzhu,Luo, Donghui,Ou, Zhi-Rong,Zhao, Mouming,Zheng, Qianwen

, p. 602 - 610 (2021/11/30)

Sargassum fusiforme polysaccharides (SFPs), including SFP-3-40, SFP-3-60, SFP-3-80, SFP-7-40, SFP-7-60, SFP-7-80, SFP-10-40, SFP-10-60, and SFP-10-80, were extracted at different pH (3, 7, and 10), and then precipitated with graded precipitation of 40%, 60% and 80% (v/v) ethanol solution, respectively. Their physicochemical properties and α-glucosidase inhibitory activity were determined. Results showed that SFPs significantly differed in the contents of total sugar, protein, uronic acid, sulfate, the zeta potential, and molecular weight distribution. SFPs, including SFP-10-40, SFP-10-60, and SFP-10-80, had bigger absolute zeta potential value and higher respective average molecular weight in the same ethanol concentration precipitate. All samples were mainly composed of fucose, glucuronic acid, and mannose with different molar ratios. The extraction pH and precipitation ethanol solution concentration caused little changes in functional groups, but significantly altered surface morphology of SFPs. Congo red test revealed that all polysaccharides were not helical polysaccharides. Rheological measurements indicated that SFPs were pseudoplastic fluids and showed elastic behavior of the gel. Except SFP-3-40 and SFP-3-60, all other samples had a stronger α-glucosidase inhibitory activity than that of acarbose. The inhibition type of SFPs against α-glucosidase varied owing to different extraction pH and precipitation ethyl concentration. This study shows that extraction pH can significantly affect the structure and hypoglycemic activity of SFPs and provide a data support for the scientific use of Sargassum fusiforme in industrial production.

Oleanane-type triterpene saponins from Aralia armata leaves and their cytotoxic activity

Yen, Pham Hai,Chuong, Nguyen Th? Hong,Lien, Giang Thi Kim,Cuc, Nguyen Thi,Nhiem, Nguyen Xuan,Thanh, Nguyen Thi Viet,Tai, Bui Huu,Seo, Yohan,Namkung, Wan,Park, SeonJu,Kim, Seung Hyun,Minh, Chau Van,Kiem, Phan Van

supporting information, p. 142 - 149 (2020/06/03)

Two new, aramatosides A and B (1 and 2), together with seven known oleanane-type triterpene saponins (3–9) were isolated from the leaves of Aralia armata. Their structures were determined by combination of HR-ESI-MS, 1 D and 2 D NMR spectral data as well as comparison with the previous literature. Compounds 6–9 exhibited cytotoxic effects towards three human cancer cell lines (HT29, A2058, and A549) with IC50 values ranging from 2.01 ± 0.17 to 18.8 ± 1.17 μM. Especially, compound 7 (narcissiflorin) showed significant cytotoxic activity against HT29 and A549 cell lines with IC50 values of 2.02 ± 1.65 and 2.01 ± 0.17 μM, respectively, which are smaller than those of positive control irinotecan hydrochloride (IC50 values of 10.3 ± 1.32 and 9.89 ± 0.19 μM).
