How are the main organic compounds (building blocks) needed to make a human body (Proteins, Fats, Carbohydrates and Nucleic Acids) represented in the Food Pyramid?

Do we need to eat everything we use to make a cell or can we make some of it ourselves?

Why do we consider certain amino acids or vitamins "essential"?

Name of Macronutrient

Subtypes of Macronutrient (We’ve listed the names to provide a framework, but explain what each means)

Food Sources (list food sources broken down by subtype of macronutrient)

Major Functions (make sure to explain each)

Recommended Intake (for you – include your demographic)

Related Health Concerns (be specific regarding how the macronutrient contributes to this health problem)

Carbohydrates

Monosaccharides Sweet, colorless, crystalline structure which contain one (mono) molecule of sugar (saccharide), with the basic CnH2nOn makeup: are the glucose and Fructose –Galactose; Sucrose, maltose and lactose

Polysaccharides is a monosaccharaides bonded togehte (wikibooks).

Which are simple?

Monosaccharides

Which are complex?

Polysaccharides

Both Monosacharides and Polysaccharides can be good healthy diet( wikkibooks).

Monosaccharides: glucose is found on some fruits, vegetable and honey; fructose is found in fruits, honey and corn syrup ( wikkibook)

Polyasacchariders

Starch (cereal grains such as wheat, oats, barley, corn rice and their products; cellulose which acts as a dietary fiber(soluble – barley-oats,rye) insoluble fiber whole grains ready to eat cereals and others) and glycogen – a storage form of glucose in the liver and muscle ( Non digestable dietary – cellulose – whole grains- green leatu vegetable; pectin- fruits, carrots, sweet potatoes. Exemple of digestable food – shellfish, animal liver.(nutrient.review,n.d)

Charts and tables are tools we use in science to break down information analytically and present data in an organized manner. It is a beneficial strategy for learning about and organizing scientific material, which we will be using often in this class. Make sure that you are detailed, thorough, and specific in your responses. Explain yourself clearly. Do not list a word or brief phrase without explaining what it means. For example, if you list diabetes for carbohydrates, make sure you explain how carbs are associated with diabetes. Don't leave the reader to make that connection for you. Also, make sure you provide APA-style references for each of your so

1. Use the following definitions and phrases to describe to which molecules of life and their subunits it belongs:

a. Energy-storing molecule, typically water soluble - b. Subunits are called monosaccharides – c. Used to speed chemical reactions - d. Subunits are joined to each other with peptide bonds - e. Most prevalent molecule in cell membranes - f. Some of them function as hormones - g. Used for storing, transmitting, and executing genetic information - h. Subunits are nucleotides

2. Weak hydrogen bonds between water molecules are responsible for the many properties of water. Acidity is expressed as pH. Buffers stabilize pH. a. What characteristics of water molecule makes it polar? Provide two examples why this property is important in microbiology. b. What is the role of buffers in living organisms, including microbes? c. What must be added to pure water to decrease OH- and/or H+ concentration, respectively

3. Carbohydrates serve as storage molecules and structural material. Lipids are hydrophobic molecules; phospholipids are main component of cell membranes. Protein has a complex structure based on identity and sequence of amino acids. Nucleic acids (DNA and RNA) are genetic station of storage information and for synthesis of proteins. ATP serve as the main energy source in the living cell. a. Name the subunits (building blocks) of carbs, simple lipids, proteins, and nucleic acids b. What level of protein structure is described as an alpha helix? c. If DNA is placed in boiling water, what and how the molecule would change?
