21. State 3 lifestyle choices that can help prevent or control type 2 diabetes. (max. 3 marks) There are 3 distinct lifestyles choices that can help prevent or control types 2 diabetes, they include: Consuming low glycemic foods that are rich in nutrients and fibre as part of a healthy diet. participating in physical activity regularly with moderate exercise maintain a healthy body weight All these choice can help an individual prevent type two diabetes. By working on choices one and two you…

Important aspects for polymers and conjugated drugs A choice of anticancer drugs have been conjugated with polymers, including anthracycline antibiotics, antimetabolites, platinum analogues, alkylating agents, as well as peptides, proteins and enzymes (Meng, and El-Deiry, 2002). The main requirement for a candidate drug in this field is the drug minimum effective concentration. For example, if the minimum effective concentration needs to be ~10 '3 M for a drug with a molecular weight of -50 kDa,…

Diseases defined by the abnormal metabolism of hemoglobin are classified as porphyrias. Porphyrias cause an abnormal buildup of porphyrin ring compounds that are essential for proper function on hemoglobin. There are multiple different classifications of porphyria, with acute intermittent porphyria being the most common. Porphyrins, the building blocks of hemoglobin, are excreted in the urine of affected people, causing extreme symptoms that range from pain to neurologic disturbances. While…

Robin Galloway Chemistry Mrs. Reichert 4/22/16 Want some toxins with your beauty? “But he who dares not grasp the thorn should never crave the rose” this was written by an English poet by the name Anne Bronte, this can be interpreted to mean that you can not be rewarded with beautiful things if you do not suffer through the pain that comes with it, but when will people realize that some things are just not worth it? In our daily lives, we are exposed to numerous chemicals…

2-Nitrobromobenzene was shown in product 1, but 4-Nitrobromobenzene could not be tested due to the small amount of product obtained. The two compounds can be distinguished by the peaks on the IR spectroscopy. 4-NBB contains an arene group, while 2-NBB contains an aldehyde/ketone group. The Thin layer chromatography plate shown in Figure 3 is used to identify compounds as well as determine their purity [9]. The crude product spot moved the same distance as the 2-NBB spot. The 4-NBB spot did not…

3. Attach sampler to the sampling pump with flexible tubing. The Waters sampler is bi-directional and can be connected at either end. NOTE: The sampler does not have a backup section for determination of breakthrough. If high concentrations of aldehydes and ketones are anticipated, connect two samplers in series. The back pressure of the sampling train will be higher and a lower flow rate may be required. 4. Sample 1 to 15 L of air at 0.03 to 1.5 L/min. NOTE: To protect from intense light, such…

1. Introduction and background The experiment that will be conducted is the preparation of benzoic acid. Benzoic acid is a carboxylic acid and this has been established in the 16th century. The molecular structure of benzoic acid can be seen in the following figure. Figure 1 – Molecular Structure Benzoic acid is used to prepare esters with the very high boiling points and is used as plasticisers. Plasticisers are compounds that are added to plastics to…

produced by the presence of sodium ions. b. Sour- Detects acidity. Most common food group that contains naturally sour foods is fruit. c. Sweet- Usually regarded as the most pleasurable sensation. This sense is produced by presence of sugars. Aldehydes and ketones are often associated with sweetness, these contain a carbonyl group. d. Bitter- Most sensitive of the taste senses. Mostly perceived as unpleasant but some bittering agents can be desirable. e. Umami- This sense is also known…

A small burette funnel was filled with column packing solvent at mobile phase, high boiling petroleum, in this case hexane (and then 10%acetone hexane mixture), and Alumina as stationary phase. When adding the sand and the alumina they have to be first mixed with the hexanes in order not to disturb the column. The Lycopene is Red- Orange and more attracted to alumina due to its high degree of Unsaturation, which can be expected to be eluted after Yellow-Orange Carotene pigments. And the other…

Formaldehyde, the most simple’s aldehyde, is a widely used agent, abundant in the environment and naturally made in organisms, is a well know carcinogenic to many organisms. The US National Toxicology Program composed of US agencies like NIH, the FDA, and the CDC have grouped formaldehyde as an agent “known to be carcinogenic” (CDC, 2014). The mechanisms by which formaldehyde produces its carcinogenic affects and the mechanism by which the cell repairs these aberrations inflicted on DNA is not…
