NOSIPHO ZUMA A00018164 BIO 120 DR HAYATU RAJI LAB 1: PH TEST FOR VARIOUS SUBSTANCES LAB PARTNERS: AMINA SULEIMAN, SEDOO ORJE-ISHEGH DATE: 27 SEPTEMBER 2016 Abstract The primary purpose of this experiment was to determine pH levels of various substances using different methods. Two techniques were used, the pH paper indicator and the pH meter. Out of ten substances that were used, five of them were found to be acidic, namely: hydrochloric acid, coke, toothpaste, milk, and acetic acid. Sodium…

to determine reducing sugar content of food sample by performing Fehling method and to identify invert sugar content of sugars by using polarimetry and also to learn property of invert and reducing sugar. Carbohydrases represent a large class of enzymes hydrolyzing polysaccharides and low-molecular-weight glycosides. They belong to the class of hydrolases. Carbohydrases are classified according to their specificity…

Methylation is a key biochemical process that is essential for the proper functioning of almost every system in your body. It occurs billions of times per second; it helps repair your DNA on a daily basis; it controls homocysteine (an unhealthy compound that can damage blood vessels); it allows the recycling of molecules necessary for detoxification; and it helps maintain mood and keep inflammation under control. To maintain the proper functioning of methylation you need an optimal level of…

Cecilia Wong Nature of the task and the research question: Two centimetre piece of potato is bathes into different salt solutions (0%, 5%, 10%, 15%, 25%, 35%) over a period of time, to determine the effect of different salt solutions on osmosis. To investigate the effect of increasing the concentration of sodium chloride (0%, 5%, 10%, 15%, 25%, 35%) on the process of osmosis, by calculating the mass change of the potato core (g, ±0.01g) at room temperate of lab (25.0˚C) Table 1: Raw data Table…

Research Question: To what extent does temperature have an affect on the enzymatic rate of reaction between starch and amylase? Background Information: Enzymes and the function of enzymes are extremely vital to the human body in regards to how quickly the body can break down the macronutrients of starch, lipids, and proteins. I chose to investigate the breaking down of a complex carbohydrate (starch) because due to their size and structure, starch is broken down more slowly than other…

For the first part, the qualitative polyphenol oxidase test (Table 1), we looked at 3 qualitative test tubes, where only test tube 2 turned orange since this tube had both the 40 mM dopa, the substrate and PPO enzyme extract. However, the test tube 3 did have a cloudy component because of the presence of PPO extract, but there was no color change. For a color change to occur, there needs to be a presence of both the dopa and PPO extract. Furthermore, we calculated the final concentrations of…

Chitin is the second most abundant natural polysaccharide consisting of β(1→ 4)-linked N-acetyl-D-glucosamine (GlcNAc) units in a linear form. Chitin is insoluble in water and mainly exists in two crystalline (α- and β-) forms. The α-chitin consists of sheets of tightly packed alternating parallel and antiparallel chains (1) and is abundant in the exoskeleton of arthropods, insects, fungi, and yeast cell walls. The chains are arranged in parallel orientation in β-chitin (2), which occurs less…

An absorbable suture is defined as a surgical suture material prepared from a substance that can be dissolved by body tissues and is therefore not permanent [1]. Any suture, which loses its tensile strength within 60 days, is considered an absorbable suture. The ideal absorbable suture has high tensile strength, low reactivity, good security and delayed absorption time. They can be classified as natural absorbable sutures or synthetic absorbable sutures. The only natural absorbable suture is…

[53]. The direct band gap energy (Eg) of Tb3+: SA crystals grown by SEST and SR methods are found to be 4.20 eV, 4.10 eV respectively, which is in good accordance with the reported values [54]. The value of band gap of Sulfamic acid was found to decrease with increase in impurity concentration and it is found between 4 and 5 [54, 55]. Fig(7). Plot of α vs. photon energy. 3.6 Thermogravimetry (TG) and differential thermal analysis (DTA) Thermogravimetry (TG) and differential thermal…
