Summary
Researchers identified six oligosaccharides from Morinda officinalis, including novel inulotriose, inulotetraose, and inulopentaose, expanding knowledge of this plant's chemical composition.
Area of Science:
- Phytochemistry
- Natural Product Chemistry
Context:
- Morinda officinalis is a traditional medicinal herb.
- Understanding its chemical constituents is crucial for pharmacological research.
Purpose:
- To isolate and characterize oligosaccharides from Morinda officinalis.
- To identify novel compounds within the plant extract.
Summary:
- Six oligosaccharides were isolated and identified: sucrose, inulin-type trisaccharide, inulin-type hexasaccharide, inulotriose, inulotetraose, and inulopentaose.
- Inulotriose, inulotetraose, and inulopentaose were identified in Morinda officinalis for the first time.
- Isolation involved chromatographic techniques, with structural identification confirmed by spectral analysis and chemical evidence.
Impact:
- This study expands the known phytochemical profile of Morinda officinalis.
- The identification of novel oligosaccharides provides a basis for further investigation into their biological activities and potential applications.

01:26Biosynthesis of Polysaccharides
Polysaccharides such as glycogen and starch are synthesized from nucleoside diphosphate sugars, primarily uridine diphosphate glucose (UDPG) and adenosine diphosphate glucose (ADPG). These activated glucose donors act as key intermediates in carbohydrate metabolism and biosynthesis. UDPG primarily involves glycogen synthesis in animals and many bacteria, while ADPG plays a fundamental role in starch synthesis in plants and certain bacteria.UDPG is formed when glucose-1-phosphate reacts with...
01:24Oligosaccharide Assembly
Protein glycosylation starts in the ER lumen and continues in the Golgi apparatus. Glycosyltransferases catalyze the addition of sugar molecules or glycosylation of proteins. Usually, these enzymes add sugars to the hydroxyl groups of selected serine or threonine residues to form O-linked glycans or the amino groups of asparagine residues to form N-linked glycans. Different positions on the same polypeptide chain can contain differently linked glycans.
