Healthy, Protein-Packed Breakfast Muffins, Cakes ... - Real Solutions

Do you ever watch people race by you with a sweet muffin or breakfast cake in hand with just a touch of envy? Could breakfast be any more convenient? And, you have to admit, pastries are just plain “missable” when you’re following a healthy nutrition plan. But then you remember that little saying, “Nothing tastes as good as being in great shape feels.” And after all, there’s always cheat day. But what if you found out about a super-secret ingredient you could add to the most decadent breakfast-type treats? What if you could saunter into the office munching on what looks like a normal, everyday, unhealthy pastry knowing that not only are you not sabotaging your fat-loss and muscle-building goals but are actually skyrocketing them? ... mouth-watering muffin, cake, or treat. We asked ourselves: Was it the Curvelle™, the new all- natural weight-loss supplement designed just for ...

Effect of konjac flour incorporated with soy protein - Academic Journals

Health food products have been extensively manufactured with reduced or no added fat, sugar and salt in combination with the addition of functional ingredients. These products may be used to prevent or decrease the risk of coronary disease, obesity, some cancers and other chronic diseases, as well as to provide healthpromoting substances and nutrients (Newsome, 1993). Gums or hydrocolloids have been used as fat replacement in many foods based on their ability to provide viscosity and body and in some cases form gels, which control rheological characteristics of aqueous and emulsion systems, reduce or control crystallization and inhibit syneresis (Lucca and Tepper, 1994). ... reduced-fat cakes with significantly lower (p < 0.05) in specific volume, but higher (p < 0.05) in weight loss and water activity. All reduced-fat ...

Biochemical and genetic analysis of the yeast proteome with a ...

Functional analysis of the proteome is an essential part of genomic research. To facilitate different proteomic approaches, a MORF (moveable ORF) library of 5854 yeast expression plasmids was constructed, each expressing a sequence-verified ORF as a C-terminal ORF fusion protein, under regulated control. Analysis of 5573 MORFs demonstrates that nearly all verified ORFs are expressed, suggests the authenticity of 48 ORFs characterized as dubious, and implicates specific processes including cytoskeletal organization and transcriptional control in growth inhibition caused by overexpression. Global analysis of glycosylated proteins identifies 109 new confirmed N-linked and 345 candidate glycoproteins, nearly doubling the known yeast glycome...Biochemical and genetic analysis of the yeast proteome with a movable.

Discovering functional relationships: biochemistry versus genetics

Biochemists and geneticists, represented by Doug and Bill in classic essays, have long debated the merits of their methods. We revisited this issue using genomic data from the budding yeast, Saccharomyces cerevisiae, and found that genetic interactions outperformed protein interactions in predicting functional relationships between genes. However, when combined, these interaction types yielded superior performance, convincing Doug and Bill to call a truce....Jun 27, 2005 ... Acknowledgements.

1 National Laboratory of Protein Engineering and Plant Genetic Engineering, Peking University,. Beijing 100871, China. 2 Department of Biochemistry and ...3-Ketoacyl-CoA synthase catalyses the initial condensation reaction during fatty acid elongation using malonyl-CoA and long-chain acyl-CoA as substrates. Previously, it was reported that several genes encoding putative cotton 3-ketoacyl-CoA synthases were significantly up-regulated during early cotton fibre development. In this study, GhCER6 cDNA that contains an open reading frame of 1479 bp, encoding a protein of 492 amino acid residues homologous to the Arabidopsis condensing enzyme CER6, was isolated and cloned. In situ hybridization results demonstrated that GhCER6 mRNA was detected only in the elongating wild-type cotton fibre cells. When GhCER6 was transformed to the Saccharomyces cerevisiae elo3 deletion mutation strain that was deficient in the production of 26-carbon fatty acids and displayed a very slowgrowth phenotype, the mutant cells were found to divide similarly compared with those of the wild-type cells. Further, heterologous expression of GhCER6 restored the viability of the S. cerevisiae haploid elo2 and elo3 double-deletion strain. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis showed that GhCER6 was enzymatically active since the yeast elo2 and elo3 double-deletion mutant expressing the cotton gene produced verylong-chain fatty acids that are essential for cell growth...

Genetic and biochemical characterization of YrkF, a ... - Virginia Tech

Biochemical, genetic, and bioinformatic approaches were used in order to characterize YrkF. First, YrkF was overexpressed and assayed for rhodanese activity ... Sulfur-containing compounds such as thiamin, biotin, molybdopterin, lipoic acid, and [Fe-S] clusters are essential for life. Sulfurtransferases are present in eukaryotes, eubacteria, and archaea and are believed to play important roles in mobilizing sulfur necessary for biosynthesis of these compounds and for normal cellular functions. The rhodanese homology domain is a ubiquitous structural module containing a characteristic active site cysteine residue. Some proteins containing a rhodanese domain display thiosulfate:cyanide sulfurtransferase activity in vitro. However, the physiological functions of rhodaneses remain largely unknown. YrkF, the first rhodanese to be characterized from Bacillus subtilis, is a unique protein containing two domains, an N-terminal Ccd1 domain and a C-terminal rhodanese domain. Ccd1 (conserved cysteine domain 1) is a ubiquitous structural module characterized by a Cys-Pro-X-Pro sequence motif. Thus, YrkF contains two cysteine residues (Cys15 and Cys149), one in each domain...
