Sugars: Glucose And Fructose

The purpose of this investigation is to test the effect of different sugar sources on yeast respiration.

Carbohydrates have two functions which is, provides short term energy and structure in some organisms. They have an atomic makeup of Carbon, Hydrogen, and Oxygen, with a 2:1 ratio of Hydrogen to Oxygen. The monomer is a monosaccharide which contains a single sugar. A couple examples of this would be glucose, fructose, and deoxyribose which is found in DNA. Yet, foods with this monomer in it would be mostly fruits, candy, and soda. Carbohydrates also have a polysaccharide which is a polymer made of many monosaccharides strung together. Some examples of these are starch, glycogen, cellulose, and chitin. A starch is storage from glucose in plants(potatoes, pasta, waffles, and toast). Glycogen is storage from glucose in animals. Cellous is structure in plants (cell wall). Chitin is structure in animals (exoskeleton).

A monosaccharide is a carbohydrate that doesn’t hydrolize. A disaccharide is a group of that yield monosaccharides on hydrolosis. Lastly, polysaccharide is a carbohydrate that contains more than three monosaccharide units per molecule.

Carbohydrates are macromolecules which and contains carbon, hydrogen and oxygen (C,H,O). There are also two types of sugars, sweet soluble and starches which are non-soluble. Sugars can also be single or simple sugars.Carbohydrates can be found in a wide variety of foods such as pasta, wheat and grains, rice, potatoes, fruits and sugars. Carbohydrates are broken down into

a) What is meant by “sugar”? What is a “carbohydrate”? How are sugars and carbohydrates related?

Monosaccharide are made up of one sugar unit, disaccharides are made of two sugar units, polysaccharides are long chains of sugar units.

I have chosen the documentary “The Secrets of Sugar” which is produced and directed by Neil Docherty and is an episode of “The Fifth Estate” which is an investigation style documentary program that airs on the Canadian Broadcasting Corporation’s channel. Beginning with the demographics, the target audience of this documentary is young adults who are busy raising children and have no time or clue for thinking about the nutrition value or ingredients contained in their everyday diet. The main purpose is to convince this particular set of demographics, baiting them with the fact that the amount of sugar they consume unknowingly is of a high level and absolutely harmful for their health. To achieve this, various techniques are used that manipulate

    Unknown four is C12H22O11, or sucrose. Sucrose is a mixture of two sugars, glucose, and fructose. Glucose is a sugar found in blood and Fructose is a sugar found in fruit. However this substance is most commonly known as plain old sugar. Sugar is used to sweeten food, drinks and other materials. We predicted it was sugar for multiple reasons, one, it was very sticky, and two, because when burned it blew up like a marshmallow.

Sugar(C12H22O11) what: sugar is a sweet crystalline carbohydrate obtained from mainly sugarcane and sugar beets consisting mainly(activated by) of sucrose and

First and foremost, the initial hypothesis of this experiment is that stevia, a plant-based and water-soluble sweetener, will inhibit the activity of the studied enzyme, α-amylase and that sucralose (i.e Splenda), an artificially produced sweetener, will have the opposite effect. Both stevia and sucralose designed for diabetics are expected to inhibit the activity of α-amylase more than sucrose. With this in mind, the results obtained from the experiment showed that stevia does indeed inhibit the activity of α-amylase most effectively compared to sucrose and sucralose. This can be explained by the small range of % inhibition values, ranging from 10-20 % inhibition. This can be observed in Figure 1 where one can notice that the standard error bars are

This is because glucose is the simplest type of carbohydrate (monosaccharide). However sucrose is a

pyruvate (3 carbon sugar), 2 NADH and 4 ATP (2 net) per molecule of glucose. During

Carbohydrates are the product that made up from carbon, hydrogen and oxygen. Carbohydrates are form by the combination of carbon dioxide and water molecules. The carbohydrates contain two specific functional group in it which is the hydroxyl groups and carbonyl groups.A reducing sugar is a type of sugar with is an aldehyde group.This means that sugar can act as a reducing agent.The procces of reducing sugar is isomerisation,example of reducing sugar islactose,maltose,glucose and fructose.All monosaccharides are capable of reducing other chemicals such as copper (II) sulphate to copper oxide.Beside that disaccharides such as maltose and lactose are reducing sugar,however sucrose is non reducing

The production and discovery of sugar grasped civilizations by its amazing taste and capabilities. Sugars effect on farming changed how the Americas farm to this day, and has also created huge trade exchanges between continents and countries . One of the main reasons for slavery to exist for so long in the Americas was because of sugars high demand. So plantation owners had to search for more sustainable workers which led them to Africa. The constant bringing of workers expanded trade in the 1500s. Sugar also led to major milestones in history and changed food in many societies. It changed how we eat and how we use our world 's resources. It led the way for modern innovations in sugar cultivation and has given us more than sweetness. Sugar has helped scientists formulate new types of fuels which could be created through sugar cane.

1) Monosacchrides: Mono means single and saccharides refer to sugar. These are the simple form of carbohydrates that consists carbon, hydrogen and oxygen in the ratio of 1:2:1 (Ahmed 2014).
