Saliva

amylase Dependent variables: • the enzymatic activity • the colour change of the saliva solution Controlled variables: • the temperature • ph Planning (b) – Pl (b): Requirements: 1. distilled water 2. 0.5% starch solution 3. buffer…

The commonly used test for saliva in the forensic laboratories are presumptive tests for the presence of amylase, not a confirmatory test, amylase, which is merely a component of saliva. The amylase tests which is usually either the Phadebas test or the starch-iodine radial diffusion test, will indicate a positive result if amylase is present and will also give an indication for the quantity of amylase present. Generally, a strongly positive amylase test is a good indication for the presence of…

However a lot of work has been done to look at how saliva is produced, including some of its benefits such as preventing dental caries (Dawes 1970). Some studies have also looked at how the changes in salivary amylase can correlate to stress levels in an individual (Douglas et al. 2007). The main research that has been conducted to look at the relationship between salivary amylase and ancestral diet is a paper by Perry and his colleagues titled, “Diet and the evolution of human amylase gene copy…

Analysis and Discussion The hypothesis that amylase would no longer hydrolyse the starch solution into maltose past 37°C was not supported by the data. Fig 1b, Fig 2.1 and Fig 2.2 all show the colour samples for various temperatures taken at increments of 10 seconds up to 40 seconds. Initially, 4°C was the slowest followed by 19°C then 37°C, 45°C, 80°C and 60°C being the fastest acting in the first 30 seconds. 80°C was the second-fastest acting temperature up until 20 seconds, but slowed down…

Introduction: Salivary gland tumor is a tumor that forms in tissues of a salivary gland. Salivary gland cancer is rare, with 2% of head and neck tumors forming in the salivary glands, the majority in the parotid. Ulttrasonography plays a very significant role in the diagnosis and management of salivary gland lesions. CT scan is useful for evaluating intraglandular component of mass. AIMS & OBJECTIVES: To study the appearances of salivary gland tumors including major and minor salivary glands…

ASSOCIATION BETWEEN AMYLASE ENZYME AND AMY1A GENE COPIES Muntaha Ahmed – 400145234 Biology 1A03 Lab Section: L16 Lab TA: Samantha Li November 22, 2017 ABSTRACT This research experiment was conducted for the purpose of attempting to find a relation between the amylase (AMY1A) gene copy numbers and the production of the amylase enzyme (mg/mL) (Tracey 2017). The results for this experiment were obtained in laboratory experiments we conducted, through which we had found the number of…

(Brooker-2011) FERRITIN is a protein that stores iron and releases it in a controlled fashion. (Frey et al. 1995) INTESTINAL ANGINA is when eating food, stomach and intestines stop resting and start to work. The wall of intestines contains muscle that pushes the food eaten and keeps it moving. (Komaroff-2012) NEGATIVE CONTROL is when there is no reaction is expected to occur on the experiment and the result is always negative. (Lipstitch-2010) PERISTALSIS is the rhythmic contraction of muscles…

I’m round but I’m not a wheel, I’m loved by a monster but I’m not the Bride of Frankenstein, I sometimes contain chips but I’m not a computer, I go well with milk but I’m not a bowl of cereal, I’m made of dough but I’m not a loaf of bread, What am I? Yay, that’s right cookies. Moist cookies can absorb milk, moist cookies are easier to chew, and moist cookies are usually fresh. If you can’t tell already moist cookies are better than dry. Moist cookies absorb the milk better than dry cookies…

1. What enzyme in the infant is lacking? Explain your answer The lacking enzyme in the infant is glucose-6 phosphatase. When blood glucose is low, glycogen breakdown in liver produce glucose-6-phosphate. G6P release glucose into blood using glucose-6-phosphatase enzyme. This patient is lacking this enzyme so the blood glucose level is low. 2. What is the metabolic reason for elevated levels of blood lactate in this patient? What are the biochemical sources of lactate? Because of the deficiency…

Personal Engagement: Consequently, I drew interest and curiosity in this particular investigation for several reasons. These substances have not been something new for me, I´ve had previous small experiments using these substances and ever since those experiences I have been very intrigued in their efficiency. I wondered if amylase could break down starch faster and better depending on changes in variables, one variable came to mind regularly. That variable was temperature, did amylase…
