Part 1A Analysis questions: 1. How many “chainobeads” was your enzyme able to make per minute in the 0 – 15 second interval? Our enzyme was able to make 6 chainobeads in the 0-15 interval. 2. How many “chainobeads” was your enzyme able to make per minute in the 60 – 120 second interval? Our enzyme was able to make 49 chainobeads in the 60-120 intervals. 3. Did your enzyme’s rate change over time? How does this compare to a real enzyme? The enzyme’s rate did change over time. This compares to a

Introduction: Hurler Syndrome (MPS-I)‚ otherwise classified as Mucopolysaccharidosis‚ is the most severe form of this disease and is caused by cells being unable to break down dermatan sulfate and heparan sulfate during regular metabolism(Laberge‚ 2010). The build up of these two by-products disturbs regular cell functionality and this may cause damage within the tissues of organs (Laberge‚ 2010). Two major symptoms found within an individual with Hurler Syndrome are skeletal deformities and

and it is the carbohydrates‚ proteins‚ and acids that will undergo significant reactions during roasting to produce coffee. The important groups of carbohydrates in beans are from the monosaccharides and the polysaccharides found in beans. The disaccharide Sucrose (C12H22O11) also plays a vital role later on in coffee. Generally speaking‚ Monosaccharides represent the simplest forms of sugars‚ such as glucose and fructose‚ and usually follow the formula Cx(H2O)y. These sugars serve as building blocks

for its nutritive and therapeutic. It has been used as a sweetener and flavoring agent in foods and beverages. The sweetness of honey is due to the different forms of carbohydrate present in honey such as monosaccharides‚ fructose‚ glucose and disaccharides‚ maltose‚ isomaltose‚ maltulose‚ sucrose and turanose (Ayoub Meo et al.‚ 2016). Honey is rich in Vitamin B6‚ Vitamin C‚ trace vitamin B‚ amino acids‚ antioxidants‚ folic acid‚ iron‚ minerals‚ zinc and niacin (David‚ 2007; Fatimah et al.‚ 2013)

The objective of this macromolecules lab was to identify the presence any of the major macromolecules in various every day food items. The three macromolecules that this lab was carried out for were carbohydrates‚ lipids‚ and proteins. There were five different experiments conducted and each of those experiments had one factor in common‚ they all had the same controls. The controls in this lab activity were already set for the lab activity. The controls were the distilled water and the baking soda
