(see table #2) The mixture with the bean water caused the solution to not be as concentrated, limiting the amount of oligosaccharides that the alpha galactosidase can break down, therefore resulting in a small amount of glucose concentration. The highest stand standard deviation is at 4 mL of alpha galactosidase, which is 185.742. The lowest standard deviation is at 0 mL and 1 mL of alpha galactosidase, which is 0. Since error bars are not all overlapping, it shows that there was a significant difference (see figure #3). However, the R squared value is 0.929, meaning that it is close to fitting the line of best fit.
Bile is a fluid produced by the liver and is made up of several substances, including cholesterol, bilirubin and bile salts (WebMD. 2005-2015).The majority of gallstones remain in the bladder (cholelithias) and may show no symptoms (silent gallstones), it may be eventually be discovered during investigation or at autopsy. Impaction of a gallstone in the neck of the gallbladder results in gallbladder inflammation and the symptoms and signs of acute or chronic cholecystitis. (Summerfield, 2010). There two main types of gallstones, they are cholesterol stones: usually yellow-green in color, approximately 80% of gallstones are cholesterol stones.
paracasei isolated from the Portuguese dairy industry was found to be 2.5 mg/ml with surface tension 41.8 mN/m (Gudina et al., 2010). Those surfactants can decrease the surface tension of water or PBS around 36-39 mN/m and even their cmc values ranges from 1.0-20 mg/mL. As compare to the chemical surfactant surface tension reduction and cmc values it has been very close to the surface tension reduce by the SDS (Sodium dodecyl sulfate) i.e. 37.0 mN/m and 1.8 mg/L respectively. Biosurfactant produced by the Lactobacillus spp.
The different possible substrates for avocado catechol oxidase have very different Km’s and Vmax’s (Table 1). The Km’s range from 0.7 to 95, and the Vmax’s range from 0.58 x 105 to 17 x 105. The enzyme’s own substrates catechol has a Km of 6.5 and a Vmax of 5.4 x 105. Some of the substrates are better suited for catechol oxidase than others. For example, dopamine has a Km of 95 and a Vmax of 11 x 105.
Since our protein has seven histadine amino acids and no other amino acids present so the protein should have high affinity, in this way we will use column binding instead of batch binding to purify protein. Flow the mixture through the column. Save small amount of eluate. 3. Wash beads with His Binding Buffer.
It serves to retard evaporation, allows smooth movements of the lids, prevents contamination of the tear film, and thickens and stabilizes the tear film. The middle layer the widest at 7.0 µm is the aqueous layer produced by the main lacrimal gland as well as accessory lacrimal glands of Krause and Wolfring. Aqueous tear deficiency is the most common cause of dry eye. Aqueous layer constitutes over 90% of tear film. The layer closest to the cornea is the mucin layer 0.02-0.05 µm thick, produced by conjunctival goblet cells.
When the food is passed into the small intestines it is mixed with three liquid. It includes bile which is a bitter greenish-brown alkaline fluid that aids digestion and is secreted by the liver and stored in the gallbladder. Pancreatic juice which is obviously made by the pancreas and intestinal juice. In addition, they’re also enzymes including maltose, sucrase to process the sugar. In the small intestine is where the food breaks down and passes through the walls containing finger like projection called the villi, so you can get the nutrition from it all.
Casein and whey are now accessible to pepsin (the active form of pepsinogen) to be broken down into peptides for easier digestion in the small intestine. Casein represents about 80% of milk protein and functions to form a clot in the stomach for efficient digestion. The globular proteins of milk whey are beta-lactoglobin, alpha-lactalbumin, bovine serum albumin and immunoglobulins, and are more water soluble than caseins (Haug,
CALCULATIONS In this experiment, we used both corn and wheat starch and observe the gelatinization of them at different temperatures. The composition of corn starch is found as 10.2% moisture and 88.8% carbohydrate. (“Corn Starch”, n.d) The remaining parts are ash, fat and protein. However, their percentages are very small and hence we can neglect them. On the other hand, the composition of wheat starch is found as 13% moisture and 86.30% carbohydrate.
In most foods, microbial contaminations occur predominantly at the surface, meaning using edible films such as chitosan allows minimal space between the foods’ surface and its’ environment. However, the coating has weak mechanical properties, and is permeable for gas and water vapour. Blending chitosan with starch improves its mechanical properties and allows a better novel food preservative. ADVANTAGES: - As chitosan is the second most abundant carbohydrate after cellulose, it’s not unusual that its waste exceeds 25bn tonnes per year. Using chitosan as a food preservative allows for reuse of this waste, making its use environmentally beneficial; while also reasonably cheap and cost-effective in production and usage.
