Carbohydrates are a large group of organic compounds that include sugars, starch, and cellulose. (dictionary.com) There are two types of sugars: the simple sugars, which are monosaccharide, meaning they contain one molecule. An example of a simple sugar is glucose. The other type of sugar is complex sugars, which are polysaccharides, meaning they have chains of sugar molecules, and an example of a complex sugar is starch. Carbohydrates are sugars and starches that provide energy for humans and animals (T. Thompson). Carbohydrates can be found in bread, pasta, cookies, and cantaloupes. Glucose is a simple sugar that is an important energy source in living organisms and is a component of many carbohydrates (dictionary.com). Glucose is one of the primary molecules that serve as energy sources for plants and animals, it is also a major energy source for most cells in the body (Shipman and Tillery on hyperphysics.edu). glucose is classified as a monosaccharide because it is a simple sugar. Glucose can be found in figs, apples, grapes, and apricots. Starch is a type of carbohydrate. Starch is a complex sugar, and is a polysaccharide, which has chains of sugar molecules. Your body breaks down starch into glucose, and releases the glucose into your bloodstream so it will be used for energy (Stein, healthyeating.com). A starch is a polysaccharide that functions as a carbohydrate (dictionary.com). Starch is found in cereal, grains, pasta, and rice Lipids are fats, oils, and waxes, they are insoluble in water. Many lipids are formed when a glycerol molecule combines with compounds called fatty acids. Fats are used in living things as parts of biological membranes and as chemical messengers. There are three kinds of lipids, the saturated, unsaturated, and the polyunsaturated lipids. (Prentice Hall Biology textbook pg. 46). Lipids are made from glycerol and fatty acids. Foods that have lipids are cheese, walnuts, butter, and beef. Proteins are molecules that are made of amino acids. They are a class of organic compounds that consist of large molecules composed of one or more long chains of amino acids and are an essential part of all living organisms (dictionary.com). Hormones, enzymes, and antibodies are proteins. Amino acids are the building blocks of proteins and there are 20 different amino acids. Those 20 amino acids can be arranged in millions of different ways to create different proteins, each one with a specific function in the body. The functions of proteins is to build, strengthen, and replace things such as tissue (mediLexicon international 2004-2013). Proteins are found in meat, poultry, sea foods, and beans. The indicator for starch is Lugols solution. When the solution starts out, the color is amber/orange, and it turns to a dark red or a very dark blue/black. The indicator for glucose is Benedicts solution, and the color it starts out is a light blue, and eventually turns into yellow, orange, or red. The indicator for proteins is the Biuret Reagent. The color starts out as dark blue, and turns to violet/purple. The indicator for lipids is brown paper, the color goes from brown to clear. Nutrition is the process of providing or obtaining the food necessary for health and growth (dictionary.com). A healthy diet should consist of some carbohydrates, the essential fatty acids, found in lipids, the essential amino acids, found in
principally by the type and relative amounts of the Amino acid present in the particular protein molecule. They are one of the building blocks of body tissue and also serve as a fuel source.
Protein is essential for the growth and repair of the body and maintenance of good health. The amount of protein we need are changes during the life time. Different food contains different amount and different combinations of amino acids sequences (British nutrition foundation,2012).

the nourishment we ingest. There is a lot of misconception surrounding protein. I have learned several eye opening facts about protein through the research conducted during this course. It is important to understand types of protein, the roll of amino acids, and the risks of consuming too much or too little protein. To avoid under or overconsumption of protein we should also understand how much protein we should be eating specific to our age and gender, identify good sources of protein, and note negative…
that contains protein is digested into amino acids that’s used later to replace the proteins in our bodies. Food that protein is found is: Meats, poultry, fish, legumes, tofu, eggs, nuts and seeds, milk and milk products, grains, some vegetables, and some fruits. There are 20 different amino acids that join together to make all types of protein. Amino acids are like building blocks, amino acids cannot be made by our bodies, they are known as essential amino acids.
The risks associated with protein…
Text: Understanding Nutrition: 9th, 10th, 11th, or 12th ed. Whitney/Rolfes.
Course Description and Content: Incorporates principles of human nutrition, essential nutrients, nutritional needs of different age groups, and nutrition research. Focuses on the relationship between nutrition, physical fitness, lifestyle, and health, with supporting emphases on consumer awareness, evaluation of nutrition information, eating disorders, and the importance of a balanced, varied diet.

The most important thing to a protein molecule is how the amino acids are linked. The sequence of amino acids in a protein is a type of code that specifies the protein and distinguishes one protein from another. A genetic code in the DNA determines this amino acid code. The genetic code consists of the sequence of nitrogenous bases in the DNA. How the nitrogenous base code is translated to an amino acid sequence in a protein is the basis for protein synthesis.

Dieting and weight control is a billion dollar industry. There are many types of lose weight quick gimmicks that don’t always work. In recent years, high protein diets have provided the results people are looking as it has been proven that carbohydrates will not provide the nutrients to drive results. Proteins diets are great in flavor and leave you feeling satisfied. However, much like anything in life too much of something is not good.

person’s diet to achieve balanced nutrition. Protein carries out many critical functions, including building lean body tissue and creating digestive enzymes. There are two different kinds of proteins complete and incomplete, which are found in different sources of food. A complete protein has an equal amount of all the amino acids that should be in a person’s daily diet. In order to be considered complete, a complete protein must not lack even one essential amino acid. Some sources of complete proteins…
What is a Protein?
Proteins play a critical part in the human body
Does the majority of the work in human cells
Necessary for structure, function, and regulation of tissue and
Contain large amounts of amino acids
Number of amino acid in protein structure determines function
of the protein
Any error in protein molecules can result in disease
What is a Protein?
Main functions of protein:
Antibodies: to fight viruses and bacteria to protect the body
I’m not to sure.
A fat molecule is a made out of a molecule of glycerol and three molecules of fatty acids. A saturated fat are found in animal products and processed foods
A nonessential is an amino acid that can be made by humans and so is not essential .nonessential amino acids: alanine, arginine, asparagine, aspartic acid, cysteine, glutamic acid, glutamine, glycine, proline, serine, and tyrosine.

chain amino acids. The bioactivities of these proteins possess many beneficial properties as well. Additionally, whey is also rich in vitamins and minerals. Whey protein is most recognized for its applicability in sports nutrition (Hoffman/Folvo 121).” In every journal, whey protein is described as having great effects on the body. After reading many excerpts like the one above, I knew that we discussed protein in great depth in class and knew that there were very important essential amino acids…
