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...

In celery (Apium graveolens L.), the two major translocated carbohydrates are sucrose and the acyclic polyol mannitol. Their metabolism, however, is different and their specific functions are uncertain. To compare their roles in carbon partitioning and sink-source transitions, developmental changes in (14)CO(2) labeling, pool sizes, and key enzyme activities in leaf tissues were examined. The p...

Sucrose is a disaccharide, composed of monosaccharides glucose and fructose with the molecular formula of C12H22O11. It has been known that sucrose is a natural product extracted from sugar beet or sugarcane and it plays a vital role in human nutrition and health. Sucrose has also been widely used as a raw material. In addition, sucrose permeability has been suggested as a simple and non-invasi...

background: consistency, backing process and content differences could influence cariogenic potential of foods. the aim was to compare plaque ph changes following consumption of two types of bread with different physical characteristics. methods: in this clinical trial, interproximal plaque ph of 10 volunteers with high risk of dental caries (saliva streptococcus mutans > 10 5 , high dental car...

Highly added sugar diets have been associated with various health problems such as dental caries, dyslipidemia, obesity and poor quality of life. Unfortunately, sugar consumption, especially sucrose, has increased continuously worldwide. The purpose of the study was to examine sources of sugar consumption and amount of added sucrose consumed in Thai undergraduate students. This study was carrie...

Sucrose-metabolizing enzymes in plant leaves have hitherto been investigated mainly in temperate plants, and rarely conducted in tandem with gene expression and sugar analysis. Here, we investigated the sugar content, gene expression, and the activity of sucrose-metabolizing enzymes in the leaves of Hevea brasiliensis, a tropical tree widely cultivated for natural rubber. Sucrose, fructose and ...

Hypoglycemic effects were investigated in the ethanolic extract of fruits of Phyllanthus emblica Linn. with long evans rats (100 120 g). Residual gut sucrose content, gut perfusion and disaccharidase activity studies were carried out to assess these activities. The residual gut sucrose content study was carried out to reveal the amount of sucrose remaining in the gastro intestinal tract (GIT) a...
