A comparison of plant characteristics of annual ryegrass (Oregon), Lolium multiflorum Lam., and Linn perennial ryegrass, Lolium perenne L.

Creator:: Rosell, C. H.
Abstract:: Studies were conducted to establish some characters which could be used, either in the field or in the laboratory, to differentiate between annual ryegrass (Oregon), Lolium multiflorum Lam. , and Linn perennial ryegrass, Lolium perenne L. Vernation, percentage of glumes covering the spikelets, and height of seedlings seem to be...

The role of ascorbic acid on discoloration of strawberry juice and concentrate

Creator:: Poei, Metty Soek-Kioen
Abstract:: The purpose of this.investigation was to determine how enzymes and oxygen influence the role ascorbic acid has on pigment degradation and browning during storage for strawberry juice and concentrate. The ascorbic and dehydroascorbic acid content of blanched and unblanched, nitrogen-treated and air-exposed samples of strawberry juice and concentrate was measured...

The effect of erythorbic acid on the determination of ascorbic acid levels in selected foods by high performance liquid chromatography and spectrophotometry

Creator:: Tuan, Shenhsiu
Abstract:: A high performance liquid chromatography (HPLC) procedure using a LiChrosorb-NH₂ column and a eluant buffer of 75:25 (v/v) of acetonitrile:0.05 M KH₂P0₄, pH 5.95, was developed for the successful separation and determination of ascorbic and erythorbic acids in selected food samples. Application of the method, which is sensitive, rapid and...

The ascorbic acid requirements of older adolescents

Creator:: Davey, Bessie Louise
Abstract:: The concentration of ascorbic acid in the plasma was determined on four levels of ascorbic acid intake for seven day periods in 1946-47 and on three levels of ascorbic acid intake for ten day periods in 1947-48. The subjects, eight girls and eight boys, were 16 to 19 year old...

Response of scorbutic guinea pigs to ascorbic acid and adrenocorticotropic hormone (ACTH)

Creator:: Riker, Joseph Thaddeus III
Abstract:: Thirty-six female guinea pigs were placed on a scorbutogenic diet for 14 days and then divided into groups of four. Three groups received adrenocorticotropic hormone (ACTH) with each group given 10, 20, or 40 units. Three groups each received 50 mg of ascorbic acid and three groups received 50 mg...

Influence of ascorbic acid supplementation on copper status in young adult men

Creator:: Finley, Elizabeth Bidwell
Abstract:: Thirteen healthy adult males, ages 20-40, consuming self selected diets, were given instructions to take one 500 mg tablet of ascorbic acid three times a day with their meals for a period of ten weeks. The effect of this daily supplementation on copper status was investigated. An estimation made from...

Some potential mechanisms for finely-tuned regulation of phospholipase C-β isozymes : studies of dimerization and phosphatidylinositol 3,4,5-trisphosphate activation

Creator:: Zhang, Yong
Abstract:: Phospholipase C-β (PLC-β) isozymes are key effectors in G protein-coupled signaling pathways. Prior research suggested that some isoforms of PLC-β may exist and function as dimers, but little is known about dimerization of PLC-β. Data from coimmunoprecipitation assays of differentially-tagged PLC-β constructs and sizeexclusion chromatography of native PLC-β support homodimerization...
