Paramylon - an overview | ScienceDirect Topics
Paramylon is a large porous molecule and plays a range of roles in chemical storage, ion exchange, and acts as a molecular sieve. Because of its homogeneous, fine and granuliform structure, the use of paramylon in cosmetics and as a novel filler material [94].
STRUCTURE OF THE EUGLENOID STORAGE CARBOHYDRATE, PARAMYLON
Paramylon, the euglenoid storage carbohydrate, was studied by transmission electron microscopy (thin sectioning, negative staining, and freeze-etching) and scanning electron microscopy in order to develop a three-dimensional model of paramylon structure.
Paramylon - Wikipedia
The paramylon is stored in rod like bodies throughout the cytoplasm, called paramylon bodies, which are often visible as colorless or white particles in light microscopy. Their shape is often characteristic of the Euglena species that produces them. [2]
The Characterization and Functional Properties of Euglena gracilis ...
Paramylon is a storage polysaccharide from Euglena gracilis, a linear glucan linked by β-1,3 glycosidic bonds . Due to the high versatility of Euglena gracilis , paramylon can be produced either in photoautotrophic or heterotrophic conditions, and it accumulates up to 50∼70% of the dry weight of the cell under heterotrophic growth conditions.
X-ray and dissolution studies of paramylon storage granules …
Paramylon is the β-1,3 glucan storage carbohydrate in the euglenoid algae. Mature paramylon granules are highly crystalline, fibrillar, and have a complex substructure. X-ray diffraction was used to demonstrate that mature paramylon granules are …
Crystal structures and crystalline elastic modulus of paramylon …
May 20, 2019 · In this study, the four paramylon ester derivatives, paramylon propionate (PaPr), paramylon butyrate (PaBu), paramylon valerate (PaVa), paramylon hexanoate (PaHe), were prepared and their crystal structures were determined by wide-angle X-ray diffraction.

Jun 1, 1988 · Summary Paramylon is the ß-1,3 glucan storage carbohydrate in the euglenoid algae. Mature paramylon granules are highly crystalline, fibrillar, and have a complex substructure. X-ray...
Structure of the euglenoid storage carbohydrate paramylon
Parmylon, the euglenoid storage carbohydrate, was studied by transmission electron microscopy (thin sectioning, negative staining, and freeze-etching) and scanning electron microscopy in order to develop a three-dimensional model of parmylon structure.
Unique Dynamics of Paramylon Storage in the Marine …
Apr 1, 2020 · Out of the diverse euglenozoans with lifestyles ranging from parasitism to photosynthesis (Adl et al. 2018), only the euglenophytes carrying the secondary plastid are known to deposit glucose via β-1,3-glycosidic linkage, forming a storage polysaccharide known as paramylon (Kiss and Triemer 1988).
Ultrastructural and immunocytochemical investigation of paramylon ...
May 8, 2017 · In the ultrastructural investigation of Ploeotia costata cells, no granules, vacuoles, or any other inclusions could be identified that would qualify for the storage carbohydrate paramylon typical for euglenids and comparable to that found in P. trichophorum (Fig. 3e).
