Identification of some esterases of the green bean (Phaseolus vulgaris L.)

Creator:: Putnam, Teryl Beebe
Abstract:: This investigation was conducted to differentiate the esterases in a water extract of freeze-dried green beans on the basis of inhibitor and substrate specificities. An attempt was made to classify these esterases according to the criteria used for animal esterases. Activity of the esterases was measured manometrically using the Gilson...

An evaluation of composition and quality of ground beef sold in retail stores

Creator:: Lee, David Bing-en
Abstract:: The composition and some qualitative aspects of ground beef offered for sale in Corvallis, Oregon were studied. Samples were purchased from six retail markets twice weekly throughout a six week test period. Three stores were independently owned and operated and three were chain stores. Differences in moisture, fat and protein...

Influence of aging temperature on bovine sarcoplasmic proteins

Creator:: Thompson, Garet Barton
Abstract:: Effects of high temperature aging upon certain characteristics of bovine l. dorsi muscle were studied. Paired wholesale ribs of carcasses were obtained subsequent to slaughter. The left rib of each pair was held at 30°C for 24 hours, then stored at 3°C. Analogous right ribs were immediately stored at 3°C....

An investigation of the effects of nutritional status on the action of insulin in rainbow trout (Salmo gairdneri)

Creator:: Ablett, Richard F.
Abstract:: Three studies were conducted to evaluate the relationship between insulin and nutritional parameters in rainbow trout. In the first study effects on growth parameters and tissue composition of rainbow trout were investigated following injection of bovine insulin at two dose levels every 48 hr for 56 days. In addition, [¹⁴C]-leucine...

Aflatoxin B₁ metabolism by rainbow trout (Salmo gairdneri)

Creator:: Schoenhard, Grant Louis
Abstract:: Aflatoxins B₁, Q₁ and aflatoxicol, R [subscript o] F, but not B₂ were activated in the presence of NADPH by the 105,000 x g pellet from rainbow trout (Salmo gairdneri), Mt. Shasta strain, liver to products lethal to Bacillus subtilis GSY 1057 (metB4, hisAl, uvr-1). Electron microscopy confirmed the microsomal...

Physicochemical Properties of Frozen Fish Muscle as Affected by Trimethylamine-N-oxide demethylase (TMAOase)

Creator:: Lee, Jinhwan
Abstract:: Gadoid fish, like Alaska pollock and Pacific whiting, have a high level of trimethylamine-N-oxide demethylase (TMAOase) that catalyzes the breakdown of trimethylamine-N-oxide (TMAO) to formaldehyde (FA) and dimethylamine (DMA) even during frozen storage. FA reacts with amino acid residues to promote covalent cross-links in the formation of inter- and intramolecular...

Identification of some soluble esterases of the carrot (Daucus carota I.)

Creator:: Carino, Lourminia Almeda
Abstract:: Substrate and inhibitor specificities have been used to classify esterases. The purpose of this work was to determine the substrate and inhibitor specificities of the esterases in an aquous extract of lyophilyzed carrots. Esterase activity was determined manometrically at 37°C. The optimum pH of the carrot esterases with several substrates...

Dietary protein and aflatoxin B₁ metabolism in rainbow trout (Salmo gairdneri)

Creator:: Stott, William T.
Abstract:: Dietary protein intake has been observed to influence the induction of cancer in animals exposed to carcinogens, presumably by affecting the activities of enzyme systems which metabolize them. One such carcinogen is aflatoxin B₁ (AFB₁) a mold metabolite and frequent contaminant of foodstuffs. Variations in the levels of dietary proteins...

Induction of hepatic microsomal enzymes in rainbow trout by dietary aroclor 1254 and the effect of cyclopropene fatty acids

Creator:: Voss, Sherri Denise
Abstract:: A dietary level of Aroclor 1254 (100 ppm) was fed to rainbow trout (Salmo gairdneri) for 15 weeks to determine the effects on hepatic microsomal enzyme induction. Fish were also fed combined polychlorinated biphenyl (PCB) (100 ppm) and cyclopropene fatty acids (CPFA) (50 ppm) to determine the effects on mixed...

Feed conversion, protein utilization and growth of rainbow trout (Salmo gairdneri) fed 25 to 45 percent herring oil

Creator:: Kellems, Richard O.
Abstract:: Triplicate groups of rainbow trout (Salmo gairdneri) fed six diets; five based on fish protein concentrate (FPC) ranging in caloric density from 4.36 to 6.19 kcal/g, and one based on vitamin free casein with a caloric density of 5.26 kcal/g were evaluated with respect to diet ingredient utilization. The parameters...
