Fifty normal-weight college females tasted and rated 15 stimuli resembling cake frostings and composed of sucrose (20-77% weight/weight), butter (15-35% weight/weight), polydextrose and distilled water. Sweetness intensity ratings rose as a function of sucrose levels. In contrast, ratings of fat content were only poorly related to stimulus fat. Rather, the perception of fat depended on stimulus...

A test was carried out to see if sucrose could regulate cold-acclimation-associated gene expression in Arabidopsis. In plants and excised leaves, sucrose caused an increase in GUS activity, as a reporter for the activity of the cold-responsive COR78 promoter. This increase was transient at 21 degrees C but lasted for at least 4 d at 4 degrees C in continuous darkness. However, at 4 degrees C wi...

Soluble sugar accumulation pattern and contents were studied in two Iranian melon cultivars, ‘Suski Sabz’ and ‘Jalali Zard’ (Cucumis melo L. Inodorous). Sucrose, glucose and fructose contents were determined in different mesocarp tissues of developing fruits during days after pollination (DAP). They were characterised by enhanced accumulation of glucose and fructose during early fruit developme...

PURPOSE The purpose of the present study was to develop mathematical relationships that allow obtaining equilibrium water content and refractive index of conventional and silicone hydrogel soft contact lenses from refractive index measures obtained with automated refractometry or equilibrium water content measures derived from manual refractometry, respectively. METHODS Twelve HEMA-based hydr...

The green-fruited Lycopersicon hirsutum Humb. and Bonpi. accumulated sucrose to concentrations of about 118 micromoles per gram fresh weight during the final stages of development. In comparison, Lycopersicon esculentum Mill. cultivars contained less than 15 micromoles per gram fresh weight of sucrose at the ripe stage. Glucose and fructose levels remained relatively constant throughout develop...

Casey, Anna, Rob Mann, Katie Banister, John Fox, Peter G. Morris, Ian A. Macdonald, and Paul L. Greenhaff. Effect of carbohydrate ingestion on glycogen resynthesis in human liver and skeletal muscle, measured by 13C MRS. Am. J. Physiol. Endocrinol. Metab. 278: E65–E75, 2000.— This study investigated the effect of carbohydrate (CHO) ingestion on postexercise glycogen resynthesis, measured simult...

The changes in respiration rate and soluble sugar content of detached rice (Oryza sativa) leaves were followed during methyl jasmonate (MJ)-promoted senescence. Increase in the respiration of detached rice leaves was observed as a consequence of methyl jasmonate (MJ) treatment for 48 h. However, MJ had no effect on photosynthetic rate in rice leaves. Sucrose and glucose contents, but not fructo...

Iodine biofortification of vegetables can become an alternative (to iodized salt) method of introducing this element into human diet. Development of agronomic rules concerning its application requires detailed evaluation of iodine influence on plant physiological and biological processes including mineral nutrition and quality of yield. The aim of the study was to determine the effect of iodine...

The aim of this study was to investigate carbohydrate metabolism in rice seedlings subjected salt-alkaline stress. Two relatively tolerant (Changbai 9) and sensitive (Jinongda 138) cultivars, grown hydroponically, were stress via 50 mM solution. content the activities metabolism-related enzymes leaves roots investigated. results showed that contents sucrose, fructose, glucose increased under St...

the objective of this study was to determine the effects of diets having different fermentability on blood gases, blood metabolites and ruminal fermentation parameters in holstein dairy cows. four multiparous holstein dairy cows (665 ± 25 kg bw, 170 ± 7.0 dim and 15±1.5 kg of milk yield), fitted with rumen cannulae, were used in a 4×4 latin square design with 28-d periods. corn starch and sucro...
