Measuring protein quality

Journal of the American Oil Chemists' Society, 1979
AbstractAn alternative to the time‐consuming and expensive PER assay for measuring food protein quality is needed by the food industry. Many biological and chemical‐based assays for measuring protein quality have been described in the literature. Most of these are still too complicated, time‐consuming, or too narrow in the range of foods they will test

Meat quality and protein quality

International Journal of Food Science and Technology, 1976
Abstract Samples of meat of good and poor eating quality were assayed biologically for protein quality and analysed for connective tissue content. the low quality meat had NPU 69 and 23.6% connective tissue; the high quality meat had NPU 82 and 2.5% collagen.

Prion proteins meet protein quality control

Trends in Cell Biology, 2003
Recent work on transmissible spongiform encephalopathies (TSEs) suggests a role for protein quality-control mechanisms in both prion protein aggregation and pathogenesis. Cytosolic accumulation of prion protein seems to be neurotoxic and might occur when proteasome function is compromised and quality control is overwhelmed. These findings are discussed

Quality of protein crystal structures

Acta Crystallographica Section D Biological Crystallography, 2007
The genomics era has seen the propagation of numerous databases containing easily accessible data that are routinely used by investigators to interpret results and generate new ideas. Most investigators consider data extracted from scientific databases to be error-free.

Protein quality of some Nigerian feedstuffs. II. Biological evaluation of protein quality

Journal of the Science of Food and Agriculture, 1973
AbstractThe protein quality of some Nigerian protein concentrates were studied by conventional protein quality techniques using weanling albino rats of the Wistar Strain.The true digestibility of the concentrates were between 90 and 98% for most of the feedstuffs examined, except the cashew nut scrap kernel meals I and II, (84.6 and 84.3%); the African

Nutritional Quality of Milk Proteins

2012
The first part of this chapter outlines general aspects concerning dietary proteins, i.e. protein requirements in human diet, role and nutritional quality of proteins and methods for its evaluation (CS, Protein Digestibility Corrected AA Score [PDCAAS]), protein digestibility and efficiency of protein utilisation.

Protein Quality Control in Mitochondria

Journal of Biochemistry, 2009
Mitochondria are crucial for both life and death of eukaryotic cells. Compromised mitochondrial integrity has severe cellular consequences and is linked to senescence and neurodegenerative disorders in humans. To maintain the functionality of proteins in mitochondria, quality-control mechanisms including signal transduction pathways counteracting ...

Quality Control: Proteins and Organelles

Biochemistry (Moscow), 2002
This review summarizes materials on the mechanisms of intracellular degradation of proteins whose topogenesis is disturbed at one stage or another. Chaperone and proteolytic systems involved in this process in the endoplasmic reticulum, mitochondria, and chloroplasts of eucaryotic cells as well as those in distinct subcellular compartments of ...
