(pNPP) on enzyme activity was studied. The phosphatase enzyme was incubated with different concentrations of pNPP, ranging from 0.2 to 10.67 mM. After 15 minutes of incubation at 35°C, the amount of p-nitrophenol (pNP) was measured using a spectrophotometer. The results were expressed in a Substrate-Velocity curve (Figure 1). This curve indicated that reaction rate (velocity) increases with increasing substrate concentration of pNPP. More specifically, the curve
Effect of different temperatures on amylase activity. Literature review This study is an attempt to follow the activity of amylase because it has a major role in the life of living organisms and is found abundantly in them. Amylase is a catalytic enzyme which hydrolyzes starch into maltose and dextrin at a certain temperature (Biology.kenyon.edu, 2015). In plants such as fruits and vegetables carbohydrates are referred to starch which is polysaccharide and is converted into disaccharide and eventually
Enzymes are proteins that act as biocatalysts for a large number of reactions. They function in the transformation of macromolecules to energy and new materials, besides for growth, repair and maintenance of cells. The important of enzyme are for the degradation of the complex molecules, pectin in the middle lamella and the primary cell walls of young plant cells (Kashyap et al., 2001). The technology of enzyme become an important part in food industry. Earlier, there was limited to small number
The purpose of this literature review is to make the analysis and in depth research about how the visual loss can impact on diet. The discussion in the literature review will be based on the how the diet and the life style of the blind person or the person who is going through the visual loss impact on their daily diet. The visual loss can occur in any phase of the personal life due to the many reasons. The study will be based on how does the visual loss impact the person diet and eating habits,
background for understanding the review that follows of the risk of Acute Kidney Injury complications. A description of the acute and chronic complications associated with Acute Kidney Injury is given, in addition to key insights gained from the prominent studies that preceded this thesis. The many challenges in interpreting the
Enzymatic browning in apple Renske Hinderks Food chemistry KLI011 Group C Introduction Many fruits and vegetables contain polyphenol oxidases (PPOs), which are a group copper-proteins. PPO is located in the plastids of plant cells, whilst the phenolic compounds are located in the vacuoles. When the tissue is damaged by cutting the fruit, both the plastids and vacuoles are broken, so that PPO can come into contact with the phenolic compounds. When the cut or damaged surfaces of these fruits and vegetables
Media composition: Fermentation broth was prepared using two different substrates. The composition of the culture broth is given below: Fermentation broth using waste bread as substrate: Waste bread 1.5% (NH4)2SO4 0.2% MgSO4.7H2O 0.04% KCl 0.1% KH2PO4 0.2% Yeast Extract 0.1% pH 6.5 Fermentation broth using waste of Citrus sinsencis as substrate: Waste fruit 1.5% (NH4)2SO4 0.2% MgSO4.7H2O 0.04% KCl 0.1% KH2PO4 0.2% Yeast Extract 0.1% pH 6.5 Media preparation: Using
Aquaculture is one of the fast rising systems in the world, which has developed as an industry likely to supply protein rich food all over the world (Prasad. 1996). The demand for animal protein has gone far away beyond source as a result of the fast progression of human population in many states of the world, particularly in the emerging countries. A serious requirement is therefore essential to increase the production of protein causes. Nowadays, aquaculture is one of the fastest increasing food
metabolism, cell Growth and cell division(8). However, whether Zn centralization in air is over 15 mg/m , 3 “metal fume fever” may result; which reasons fever, depression, malaise, cough, vomiting, salivation and headache. Cadmium replaces Zn, in many enzymes. Therefore, higher sum of Zn is needed to overcome toxic impacts for cadmium (9). Iron insufficiency is seen in the premenopausal woman. In contrast to premenopausal women, grown-up men if not utilize iron supplements, because high tissue level for
