Carbohydrates are divided into two groups based on how complex their structure is.Monosaccharides is a simple carbohydrate because it has one simple sugar, disaccharides has a combination of two simple sugars.An example of disaccharides is lactose.Complex carbohydrates also known as polysaccharides are known to have multiple sugars.Polysaccharides are also used to store energy, an example of this starch.In addition, nutrients include proteins ,fats, minerals and vitamins.Multiple tests were taken like Benedict’s Solution, Lugol’s Solution, and Biuret’s Solution to test if the presence of a substance was there.

Next when the starch test was tested it changed to purple to black.Lastly when Biruret’s solution was tested it turned violet. So, the substances that tested positive were simple sugars (Benedict’s solution)and proteins (Biruret’s
The independent variable for this experiment is the enzyme concentration, and the range chosen is from 1% to 5% with the measurements of 1, 2, 4, and 5%. The dependant variable to be measured is the absorbance of the absorbance of the solution within a colorimeter, Equipments: Iodine solution: used to test for present of starch - Amylase solution - 1% starch solution - 1 pipette - 3 syringes - 8 test tubes – Stop clock - Water bath at 37oc - Distilled water- colorimeter Method: = == ==
The Benedict's Test is used to test the presence of simple sugars in a sample. If sugars are present, a color change will occur from blue to red. However, although the Benedict's test shows the presence of sugars, it cannot accurately determine the concentration of sugar in a sample solution. In our method, we added specific concentrations of glucose to the Benedict's test to use as a chart to estimate the glucose concentration of an unknown solution X. Although this gives a rough estimate of the concentration, it is very inaccurate. For example, the mystery solution X was a pale orange color, which was between the colors in my first and second test tube.
Answer: Monosaccharides means one sugar. A simple sugar that is the basic subunit of a carbohydrate and is not broken down during digestion. Ex: Glucose
A Monosaccharide is the simplest form of carbohydrates. They are usually called single sugars and are the building blocks for all bigger carbohydrates. They are classified according to the number of carbon atoms in a molecule.
Simple carbohydrates which break down quickly during digestion can cause a dangerously high level of glucose in the blood. Complex carbohydrates release glucose more steadily into the bloodstream and help prevent dangerously high levels of glucose in the blood. (Jen Grogan and Ruth Suter 2008 p. 2.1.13 – 2.1.13)
Carbohydrates, lipids, and proteins serve as a fuel for the human body. The nutrients are broken down into smaller pieces in the alimentary tract and are absorbed into the blood. This makes it possible for tissues and cells to transform the chemical energy of digestive end products into useful work. The majority of the absorbed products contain monosaccharides, glucose, monoacylglycerol, long chain of fatty...
Carbohydrates make up the largest volume of daily food in the diet. Carbohydrates include sugars, starches, and dietary fiber. Carbohydrates are considered organic chemicals because they contain carbon, hydrogen, and oxygen. They are considered a macronutrient because it needs to be consumed in large amounts in a diet which make up the majority of the diet in a day. Carbohydrates are important because they are the main source of calories for a healthy diet. How do carbohydrates affect sleep? Carbohydrates provide energy for physical activity, brain function, and operation of the organs. When carbohydrates are consumed, they are converted to fuel and used as energy. There are two types of carbohydrates known as simple carbohydrates and complex carbohydrates. Simple carbohydrates are sugars that are made of one or two sugar molecules and are rapidly digested. Complex carbohydrates are dietary starches and made of sugar molecules that contain fiber. They are found in whole plant foods which are high in vitamin and minerals. The glycemic index is a “relative ranking on how they affect blood glucose levels.” (University of Sydney) Foods with a low glycemic index are more slowly digested, absorbed, and metabolize so the blood glucose rises more slowly. Foods with a high glycemic index are more quickly
The first example of why are carbohydrates are significant to an individual's health has to do with various amounts of food (Argument #2). Carbohydrates are in all kinds of food, such as fruits, pastas, meats, and veggies (#2). Carbohydrates are divided into two kinds of groups, unrefined and refined foods (#2). Unrefined foods are the healthy foods such as pears, veggies, and types of meats. Refined foods are unhealthy foods such as candy, types of snacks, and other types of unhealthy vegetables (#4).
Complex carbs are fruits, vegetables, nuts, whole grains and beans. Fiber and starch are two of the ingredients you'll find in complex carbs. You can find them in whole wheat breads, whole grain cereals, and brown rice. Some foods are higher in starch than fiber, and it's best to stay away from them as much as possible. They're still good for you, but the high starch can be a problem. Those foods are peas, corn, and some cereals.
Carbohydrates include sugars and starches, contain carbon, hydrogen, and oxygen which appears in a ratio of 1:2:1. Carbohydrates are classified according to size as monosaccharides, disaccharides, and polysaccharides. The primary function of carbohydrates is to serve as sources of energy. Carbohydrates are some of the most numerous molecules in living organisms. They play a major role as food molecules in the cell, being broken down to produce energy. Polysaccharides play an important role serving as energy reserves also. It provides a quick-release energy source that keeps us going between meals. Small amounts of carbohydrates are also used for structural purposes and others are attached to outer surfaces of cell membranes to guide cellular interactions. For many cells, sugars are the most important source of energy.
The most important nutrient categories are starches, minerals, sugars, and electrolytes. Starches and minerals fit into the area of complex carbohydrates. Complex carbohydrates are polysaccharides (many sugars bonded together). Because of the multiple bonds, polysaccharides are able to store energy for later use. Simple sugars make up the other group of carbohydrates. The bonding structures of simple sugars are much less advanced that than those of complex carbohydrates. This allows for the burning of simple sugars in an athlete's body. Electrolytes are a category of their own because they are helpful to an athlete all of the time, whether energy storage or energy burning is needed.
Exact amount of solution of the reagents (Benedict’s Solution, Sudan III Stain, Iodine and Biuret Reagent) for the specific tests (Simple Carbohydrates, Lipid, Complex Carbohydrates and Protein) was transferred into each of the test tubes.

In this lab there were two chromatography experiments, food color paper chromatography and amino acid thin layer
The dimers of carbohydrate are disaccharide including maltose, sucrose and lactose. And polysaccharides are the long chains of repeated
