Sweet Dreams (Are Made Of This): A Review And Perspectives On Aspartic Acid Production, Holly Appleton, Kurt A. Rosentrater 2021 Iowa State University

Sweet Dreams (Are Made Of This): A Review And Perspectives On Aspartic Acid Production, Holly Appleton, Kurt A. Rosentrater

Agricultural and Biosystems Engineering Publications

Aspartic acid, or “aspartate,” is a non-essential, four carbon amino acid produced and used by the body in two enantiomeric forms: L-aspartic acid and D-aspartic acid. The L-configuration of amino acids is the dominant form used in protein synthesis; thus, L-aspartic acid is by far the more common configuration. However, D-aspartic acid is one of only two known D-amino acids biosynthesized by eukaryotes. While L-aspartic acid is used in protein biosynthesis and neurotransmission, D-aspartic acid is associated with neurogenesis and the endocrine system. Aspartic acid production and use has been growing in recent years. The purpose of this article is ...

There has been an increasing global demand for large bluegill (Lepomis macrochirus) to supply the food‐fish market. Current bluegill diets resemble those for largemouth bass and contain a high percentage of marine fish meal (FM). Research into the use of alternative protein ingredients for bluegill diets need to be conducted to not only conserve finite marine resources, but to reduce cost and expand the supply of bluegill to the global market. We evaluated growth, survival and body composition of bluegill fed diets in which FM was partially or totally replaced by various combinations of soybean meal, poultry by‐product ...

Journal of Food and Drug Analysis

Glycidyl esters (GEs) and 3-chloroprapane-1,2-diol esters (3-MCPDEs) are processing contaminants in refined edible oils that have raised concerns globally owing to their potentially carcinogenic properties. Official analytical methods for GEs and 3-MCPDEs, such as AOCS Cd 29a-13 and AOCS Cd 29b-13, require up to 16 h for chemical hydrolysis. Also, parallel experiments should be conducted to correct for the conversion of analytes during hydrolysis in AOCS Cd 29b-13. For AOCS Cd 29c-13 with the shortest operating time, the reaction time (3.5-5.5 min) and temperature of alkaline hydrolysis should be carefully controlled, implying the accuracy may be influenced ...

A Convenient And Sensitive Colorimetric Iodide Assay Based On Directly Inducing Morphological Transformation Of Gold Nanostars, Rongju Zhou, Xiaohui Huang, Qingxiao An, Weizhen Xu, Yi Liu, Dong Xu, Suyan Wang, Qinlu Lin, Jianglin Zhang

Journal of Food and Drug Analysis

We propose a convenient and easy colorimetric assay for highly sensitive detection of iodide by using gold nanostars (GNSs) as probes. The assay relies on that iodide directly changes the morphology of GNSs and alters their longitudinal localized surface plasmon resonance (LSPR) without surface modifications and the use of other reagents. Upon increasing iodide concentration, GNSs gradually transformed to sphere gold nanoparticles, the absorbance at longitudinal LSPR decreased, and solution color varied from greenish blue to red, as confirmed by the UV-Vis absorption spectroscopy and transmission electron microscopy. With this strategy, as low as 0.005 μM of iodide can ...

Journal of Food and Drug Analysis

Triple-negative breast cancers (TNBCs) lack specific targeted therapy options and have evolved into highly chemo-resistant tumors that metastasize to multiple organs. The present study demonstrated that the proline dehydrogenase (PRODH) mRNA level in paired (tumor vs. normal) human breast tissue samples (n=234) was 6.6-fold greater than normal cells (*p=0.021). We established stable PRODH-overexpressing TNBC (HS578T) cells, and the malignant phenotypes were evaluated using soft agar colony formation and Transwell migration assays. The results demonstrated that PRODH induced epithelial-mesenchymal transition in cancer cells and increased cell proliferation. The present study found that the tea polyphenol epigallocatechin-3-gallate (EGCG ...

Journal of Food and Drug Analysis

The cancer-preventive activities of quercetin have been extensively studied in invasive breast cancer; however, the role of quercetin on triple-negative breast cancer (TNBC) with overexpression of insulin-like growth factor-1 receptor (IGF1R) has not been resolved. In this article, we demonstrated that quercetin inhibited the activation of IGF1R and its downstream kinases Akt and Erk1/2 in a dose-dependent manner in human MDA-MB-231 breast cancer cells (TNBC cell line). Related to this, quercetin markedly suppressed the metastatic phenotype and epithelial–mesenchymal transition (EMT) of MDA-MB-231 cells by inhibiting the expression of EMT transcription factors Snail and Slug. Quercetin also increased the ...

Plasmalogens are important phospholipids essential for maintaining cardiovascular and brain health. Ruminant meats are excellent dietary sources of plasmalogens. Globally, grilling remains a popular technique for preparing meats. However, little is known concerning how marination affects retention and quality of plasmalogens in grilled ruminant meats. Here we present information on effect of two unfiltered beer-based marinades infused with herbs and spices on plasmalogens in grilled beef and moose meats. Although total plasmalogen contents of marinated grilled meats were lower compared to unmarinated controls, compositionally, wheat ale- and India session ale-based marinades retained higher levels of PUFA plasmalogen PC (phosphatidylcholine) and ...

Journal of Food and Drug Analysis

The major goals in the management of diabetes are to maintain normal control of glucose metabolism and glycemia. Dietary modification is one of the most recommended treatment modalities for diabetic patients. The use of foods sweetened with sugar alcohols (also known as polyols) such as xylitol, sorbitol, mannitol, maltitol, lactitol, isomalt and erythritol, has brought an escalating interest. Since some sugar alcohols do not raise plasma glucose, as they are partially digested and metabolised. Diet composition and adequacy may be altered by replacing carbohydrates with sugar alcohols. It has been established that these polyols are appropriate sugar substitutes for a ...
