Two β-glucuronosyltransferases involved in the biosynthesis of type II arabinogalactans function in mucilage polysaccharide matrix organization in Arabidopsis thaliana

BMC Plant Biology, 2021
Background Arabinogalactan-proteins (AGPs) are heavily glycosylated with type II arabinogalactan (AG) polysaccharides attached to hydroxyproline residues in their protein backbone.

Pepper (Capsicum annuum) xylogen-like arabinogalactan protein (XYLP) 1 and XYLP2 promote synthesis of lignin during stem development to cope with stresses

Vegetable Research, 2022
Pepper stems exhibit a high level of strength and lignin deposition to support plant growth, which direct the cultivation style without binding sticks or scaffolding.

Using Synthetic Glycans to Investigate Anti‐Glycan Antibodies and Explore Their Medical Potential

Angewandte Chemie International Edition, EarlyView.
Anti‐glycan antibodies are essential in health and disease. Access to novel glycan structures paves the way for progress in antibody profiling for biomarker discovery, antibody development, and vaccine design. We summarize the strategies to synthesize and utilize synthetic glycans for the development and application of anti‐glycan antibodies in basic ...

Effet de polysaccharides sur la formation de trouble protéique dans un vin blanc

OENO One, 1994
La découverte récente de deux polysaccharides, une mannoprotéine de levure et un arabinogalactane- protéine (AGP) de raisin, présents en très faible quantité dans le vin et ayant un effet protecteur contre la dénaturation thermique des protéines, permet ...

The Growth Oscillator and Plant Stomata: An Open and Shut Case

Plants, 2023
Since Darwin’s “Power of Movement in Plants” the precise mechanism of oscillatory plant growth remains elusive. Hence the search continues for the hypothetical growth oscillator that regulates a huge range of growth phenomena ranging from circumnutation ...

In Vitro Activity of Citrus IntegroPectin Against Breast Cancer and Colon Cancer

ChemFoodChem, EarlyView.
Image shows microscopic photographs of MCF‐7 cells in the presence of lemon, red orange, and sweet orange IntegroPectin bioconjugates at 0.5 or 1.0 mg/mL concentration after 24 h next to a photograph of MCF‐7 cells as such (control). ABSTRACT We investigate the ability of IntegroPectin bioconjugates obtained via acoustic cavitation of lemon, red orange,

Galactan synthesis in a single step via oligomerization of monosaccharides

Beilstein Journal of Organic Chemistry, 2014
Galactans ranging in length from one to five residues were prepared in a single step by treatment of the glycosyl donor 2,3,4-tri-O-benzoyl-β-D-galactopyranosyl fluoride with lanthanum perchlorate in the presence of an initiator alcohol.
