Coconut cake is an abundant and good potential edible protein source. However, until now it has not been extensively used in the food industry. To promote its usage, the characterization, nutrition value and antioxidant activity of coconut cake protein fractions (albumin, globulin, prolamine, glutelin-1 and glutelin-2) were studied. Results revealed that all the albumin, globulin, glutelin-1 an...

Low glutelin content1 (Lgc1) is a dominant mutation that reduces glutelin content in rice grains. Glutelin is a major seed storage protein encoded by a multigene family. RNA gel blot and reverse transcriptase-mediated PCR analyses revealed that Lgc1 acts at the mRNA level in a similarity-dependent manner. In Lgc1 homozygotes, there is a 3.5-kb deletion between two highly similar glutelin genes ...

The aim of this study was to investigate the effect of in-vitro pepsin and pancreatin digestion of proteins extracted from Roselle seed on the production of bioactive peptides. Defatted Roselle seed flour was used to extract different protein fractions namely globulin, albumin and glutelin. The proteins were digested using pepsin (1 h) followed by pancreatin (1 h) in order to produce hydrolysat...

Pearl millet and soybean flour were used in this study. Investigation showed that the major fraction of pearl millet protein was the prolamin followed by globulin and glutelin, while that of soybean was the globulin followed by glutelin and lesser amounts of albumin and prolamin. Cooking of pearl millet or soybean was found to decrease the globulin and true-prolamin fractions, while the prolami...

Rice seed storage proteins glutelin and α-globulin are synthesized in the endoplasmic reticulum (ER) and deposited in protein storage vacuoles (PSVs). Sar1, a small GTPase, acts as a molecular switch to regulate the assembly of coat protein complex II, which exports secretory protein from the ER to the Golgi apparatus. To reveal the route by which glutelin and α-globulin exit the ER, four putat...

As a by-product of oil production, walnut proteins are considered as an additional source of plant protein for human food. To make full use of the protein resource, a comprehensive understanding of composition and characteristics of walnut proteins are required. Walnut proteins have been fractionated and characterized in this study. Amino acid composition, molecular weight distribution and gel ...

Rice glutelin is synthesized as a precursor in the endosperm endoplasmic reticulum and then deposited within the protein storage vacuole protein body-II (PB-II) as an aggregate, with a high degree of polymerized higher-order structure comprising mature acidic and basic subunits after post-translation processing cleavage. In order to investigate the functional role of this processing and its eff...

Abstract This work evaluated the functional properties of sesame protein fractions in order to determine their potential food applications. Sesame seed were prepared according solubility: water-soluble (albumin), salt-soluble (globulin), alkaline-soluble (glutelin) and ethanol-soluble (prolamin). Globulin was most abundant fraction, consisting 91% protein, followed by glutelin, albumin prolamin...

Protein-rich subcellular particulates were isolated by zonal centrifugation from homogenates of endosperms of normal, opaque-2, and floury-2 mutant corn (Zea maize) kernels at different stages of development. In early stages the high lysine mutants vary from normal corn by greater production of a glutelin protein not associated with the matrix. This protein is high in lysine and may become a co...

Sodium dodecyl sulfate-polyacrylamide gel electrophoretic analysis of the starchy endosperm protein of rice (Oryza sativa L. Japonica cv Koshihikari) during seed development confirmed that storage protein begins to accumulate about 5 days after flowering. Two polypeptide groups, 22 to 23 and 37 to 39 kilodaltons, the components of glutelin, the major storage protein in rice seed, appeared 5 day...
