Amaranth Globulin Polypeptide Heterogeneity
(Springer, 2007-07)
The polypeptides integrating amaranth globulin-p and 11S-globulin were characterized by two-dimensional electrophoresis, ion-exchange chromatography and RP-HPLC. All polypeptides exhibited charge and hydrophobic heterogeneity. ...
Structural Modifications of Amaranth Proteins During Germination
(Springer, 2009-02)
Amaranth storage proteins begin to be hydrolyzed immediately following the completion of germination. Albumins and globulins (7S globulin, 11S-globulin and globulin-p) were formerly modified, and glutelins, the most ...
Influence of the extracting solvent upon the structural properties of amaranth (Amaranthus hypochondriacus) glutelin
(AMER CHEMICAL SOC,, 2003-07-02)
Two amaranth glutelin preparations, Gt-bo extracted with borate buffer at pH 10 and Gt-na extracted with 0.1 N NaOH, were characterized and compared with the amaranth polymerized 11 S globulin (Gp, globulin-P). Gt-bo and ...
Amaranth seed protein hydrolysates have in vivo and in vitro antihypertensive activity
(Elsevier, 2011-06)
The objective of this work was to study the hydrolytic release of encrypted peptides with antihypertensive activity from storage proteins of Amaranthus mantegazzianus, as determined by in vitro assays, for the first time ...
Amaranth Globulin Structure Modifications Induced by Enzymatic Proteolysis
(American Chemical Society, 2000-11)
Globulin-P was partially hydrolyzed with papain under specific conditions to study the resulting structural modifications. Under mild hydrolytic conditions, globulin-P polymers were cleaved to render their unitary constituents ...
Amaranth proteins as a source of antioxidant peptides: Effect of proteolysis
(Elsevier Science, 2010-01)
The antioxidant activity of peptides present in the phosphate buffer-soluble fraction of: – Amaranthus mantegazzianus protein isolates (Is), – protein fractions (Albs, Globs, GlobPs and Gluts), alcalase hydrolysates of ...
Amaranth protein films from thermally treated proteins
(Elsevier, 2013-12)
The usefulness of amaranth protein isolates, native and thermally treated, in edible films preparation was studied. Protein films were prepared by casting using glycerol as plasticizer. Films from amaranth native protein ...
Simulated gastrointestinal digestion of amaranth flour and protein isolate: Comparison of methodologies and release of antioxidant peptides
(Elsevier Science, 2020-12)
The effect of both the simulated gastrointestinal digestion conditions and the matrix over protein hydrolysis and antioxidant peptides generation was evaluated by comparing an in-house method with COST INFOGEST-based SGD ...
Characterization of amaranth proteins modified by trypsin proteolysis. Structural and functional changes
(Elsevier Science, 2009-06)
Amaranth protein isolates were prepared from Amaranthus hypochondriacus and hydrolyzed using trypsin. Degrees of hydrolysis varied between 2% and 7% with the time of hydrolysis reaction. The structure, solubility and foaming ...
Chemical and thermal properties of flours from germinated amaranth seeds
(Springer Verlag, 2019-06)
Modification of the chemical composition of amaranth flours from Amaranth caudatus L. seeds with germination was studied. Seeds were sprouted at 30 °C for 0, 18, 24, and 48 h. Proximal composition, total phenolic content ...
