Precipitation of chymotrypsin from fresh bovine pancreas using i-carrageenan
(Elsevier, 2012-12)
The separation of chymotrypsin from a crude filtrate of fresh bovine pancreas homogenate was carried out using precipitation with a commercially available negatively charged natural strong polyelectrolyte: -carrageenan. ...
Antiviral activity of lambda-carrageenan prepared from red seaweed (Gigartina skottsbergii) against BoHV-1 and SuHV-1
(Elsevier, 2015-02)
The antiviral effect of polysaccharides has been known for many years. Carrageenans are considered a good alternative for the prevention of a wide range of diseases, mainly caused by enveloped viruses. The advantages lie ...
Platform design for extraction and isolation of Bromelain: Complex formation and precipitation with carrageenan
(Elsevier, 2017-03)
The main objective of this work was to investigate for the first time the molecular mechanism of complex formation between bromelain (a positively charged enzyme) and carrageenan (a natural strong polyelectrolyte, negatively ...
Interference in dengue virus adsorption and uncoating by carrageenans
(Academic Press Inc Elsevier Science, 2007-07)
This study demonstrated that the λ- and ι-carrageenans, sulfated polysaccharides containing linear chains of galactopyranosyl residues, are potent inhibitors of dengue virus type 2 (DENV-2) and 3 (DENV-3) multiplication ...
Carrageenans from Sarcothalia crispata and Gigartina skottsbergii: Structural Analysis and Interpolyelectrolyte Complex Formation for Drug Controlled Release
(Springer, 2018-12)
The aims of the present study were to characterize for the first time the carrageenan extracted from cystocarpic stage of S. crispata collected in the Patagonian coast of Argentina, and to prepare interpolyelectrolytic ...
Study of the release mechanism of diltiazem hydrochloride from matrices based on chitosan-alginate and chitosan-carrageenan mixtures
(AMER CHEMICAL SOC, 2005-09)
The aim of this work was to establish the diltiazem hydrochloride release mechanism from the chitosan-alginate matrix tablet (MCB/AS) and chitosan-carrageenan matrix tablet (MCS/CSI). The weight loss for MCS/CSI is mainly ...
Effect of kappa-carrageenan on the gelation of horse mackerel (T. murphyi) raw paste surimi-type
(2004)
Gelation of fresh (unfrozen) raw surimi-type paste (RS paste) from horse mackerel (T. murphyi) was studied in the presence of κ-carrageenan (0.5, 1, 2% Cκ) and KCl (0.5-2%) as a substitute for NaCl. Gelation was traced by ...
Estudo comparativo de carragenanas comerciais Kappa, Iota e Lambda no processo inflamatório em ratos :edema intraplantar e pleurisia
(Universidade Federal do Rio Grande do NorteBRUFRNPrograma de Pós-Graduação em BioquímicaBioquímica; Biologia Molecular, 2005-07-19)
The Iota, Kappa and Lambda commercial carrageenans are rarely pure and normally contain varying amounts of the other types of carrageenans. The exact amount of impurity depends on the seaweed source and extraction procedure. ...
Comparative studies on polyelectrolyte complexes and mixtures of chitosan-alginate and chitosan-carrageenan as prolonged diltiazem clorhydrate release systems
(ELSEVIER SCIENCE BV, 2004-01)
The aim of this work was to evaluate the possibility of using mixtures and/or polyelectrolyte complexes from both chitosan-alginate and chitosan-carrageenan as prolonged drug release systems. Different dissolution profiles ...
The effects of sucrose on the mechanical properties of acid milk proteins-kappa-carrageenan gels
