A pathway for steryl ester biosynthesis in acetone powder preparations from spinach (Spinacia oleracea L.) leaves has been elucidated; free sterol and 1,2-diglyceride were the substrates. Although animals synthesize cholesteryl esters by three distinct biosynthetic pathways, none of these pathways utilizes 1,2-diglyceride as an acyl donor. Phosphatidylcholine, phosphatidic acid, triglyceride, 1...

As natural plant growth stimulators, amino acids are widely used to improve the yield and quality of crops. Change in enzymes activities of N assimilation (NR, NiR and GS), residual nitrate (NO3-), soluble protein content, and yield of spinach and lettuce plants were investigated under replacing 20% nitrate-N in the nutrient solution by L-glycine and blood meal amino acids. Seeds of the mention...

Abstract Spinach ( Spinacia oleracea L.) is a popular commercial crop that used both fresh and after processing. In terms of nutrition, spinach high in minerals vitamins, particularly ascorbic acid (vitamin C). Lack nutrients the plant may be big issue cultivation, while temperature, water, sunshine also play part growth can impact production. The focus this research was to determine effect NPK...

although the indian population is largely vegetarian, not much attention has been given to the cultivation of vegetables, as compared to other crops like cereals, pulses and oil seeds. therefore, the present study was conducted on two leafy vegetables, spinach (spanacia oleracea l.) and methi (trigonella foenum graecum l.) commonly grown in aligarh, as the two popular vegetables of indian diet....

Protoplasts from spinach leaves exhibit a light-induced Ca2+ influx. The half maximum rate of Ca2+ influx is achieved at ~ 5 Wm"2. The action spectrum of this influx is similar to that of photosynthesis. Furthermore, light-induced Ca2+ influx is abolished by DCM U (2* 0.5 îm) and is sensitive to the uncoupler FCCP. Vanadate up to 3 enhances light-induced Ca2+ influx. These data indicate that ph...

The radioenzymatic method was used to determine the oxalate contents in common Japanese foods. High concentrations of oxalate were detected in spinach, Perilla frutescens, pepper, sesame, chocolate, and tea. Beer and coffee also contained some oxalate. Fruit and meat were low in oxalate content. Therefore, among the common Japanese foods, the most important foods to be avoided to restrict oxala...

The initial step of fatty acid biosynthesis in both plants and Escherichia coli is the condensation of malonyl-acyl carrier protein with acetyl-COA, a reaction that is catalyzed by KAS 111 (Jackowski and Rock, 1987; Jackowski et al., 1989; Jaworski et al., 1989; Clough et al., 1992). In E. coli, KAS 111 has been implicated as a site of regulation for de novo fatty acid synthesis (Jackowski and ...

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...
