Characteristic terahertz absorption spectra of paramylon and paramylon-ester compounds

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2021
Paramylon is a long-chain polysaccharide, composed of glucose units connected via β-(1,3) glycosidic bonds, that spontaneously forms a three-strand helical bundle. Paramylon-esters can be made by partially or fully replacing saccharide chain hydroxide groups with carboxylic functional groups, such as stearoyl (CH3(CH2)16CO) and palmitoyl (CH3(CH2)24CO).

THz spectroscopy of paramylon, paramylon-ester and cellulose

2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2019
The terahertz (THz) spectroscopy of paramylon ($\beta$-1,3-glucan) and paramylon ester extracted from Euglena have been studied by Fourier Transform Infrared Spectrometer (FT-IR) in a frequency range from 0.3 to 10 THz. The absorption spectra of paramylon were analyzed by comparing with cellulose that has a similar long-chain -(C 6 H 10 O 5 ) n ...

Synthesis and characterization of paramylon propionate-graft- poly(lactic acid) and paramylon propionate-graft-poly(ε-caprolactone)

Polymer, 2021
Abstract Paramylon propionate-graft-poly(L-lactic acid) (PaPr-g-PLA) and paramylon propionate-graft-poly(e-caprolactone) (PaPr-g-PCL) were synthesized by grafting L-lactide and e-caprolactone to the residual hydroxy group of paramylon propionate (degree of substitution (DS) of 1.6 or 2.0).

Degradation of Paramylon by Euglena gracilis

The Journal of Protozoology, 1968
SYNOPSIS. Protozoa of the order Euglenida contain a polysaccharide storage product, paramylon, composed of 1, 3‐linked glucose molecules arranged into an extremely resistant granule. An enzyme was purified from the soluble phase of Euglena gracilis which would degrade this polysaccharide to single glucose residues, providing the integrity of the ...

Spectroscopic characterization at THz frequencies of glucose-based biomaterials: paramylon, paramylon-ester and cellulose

2019 44th International Conference on Infrared, Millimeter, and Terahertz Waves (IRMMW-THz), 2019
The terahertz (THz) spectroscopy of paramylon (β-1,3-glucan) and paramylon-ester extracted from microalgae called as Euglena have been studied by Fourier Transform Infrared Spectrometer (FT-IR) in a frequency range from 0.3 to 9 THz. The absorption spectra of paramylon were analyzed by comparing them with cellulose that has a similar long-chain ...

Application of electrical treatment on Euglena gracilis for increasing paramylon production

Applied Microbiology and Biotechnology, 2021
Paramylon also called β-1,3-glucan is a value-added product produced from Euglena gracilis. Recently, researchers have developed various strategies for the enhanced paramylon production, among which electrical treatment for microbial stimulation can be an alternative owing to the applicability to large-scale cultivation.

Anti-HIV (human immunodeficiency virus) activity of sulfated paramylon

Antiviral Research, 1993
Sulfated derivatives of paramylon, a water-insoluble (1-3)-beta-D-glucan from Euglena gracilis, significantly inhibited the cytopathic effect of human immunodeficiency virus (HIV-1, HIV-2) and the expression of HIV antigen in cultured MT-4, MOLT-4 cells and human peripheral blood mononuclear cells.

STRUCTURE OF THE EUGLENOID STORAGE CARBOHYDRATE, PARAMYLON

American Journal of Botany, 1987
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.

THE INTRAMEMBRANOUS PARTICLE PROFILE OF THE PARAMYLON MEMBRANE DURING PARAMYLON SYNTHESIS IN EUGLENA (EUGLENOPHYCEAE)¹

Journal of Phycology, 1988
ABSTRACTParamylon is the β‐1, 3‐glucan storage product in euglenoid algae. It is a fibrous crystal that occurs as membrane‐bound granules in the cytosol. The role of the surrounding membrane in paramylon synthesis was investigated by the use of freeze‐etch electron microscopy.
