1) First, find out what nutrients Janine and Mitchell are talking about. Using a biology textbook and the resources listed, describe what the following molecules are and what they are used for in the human body. List some specific examples of each. Also list major dietary sources of each.
a. Proteins
Description: macromolecules made of amino acids
Functions: cell synthesis and repair, transporting molecules in the blood, speed up chemical reactions, serve as antibodies, and store amino acids
Examples: rice, beans, meat, whole-grain cereal, legumes, nuts, seeds, milk
b. Carbohydrates
Description: molecules that contain carbon, hydrogen, and oxygen
Functions: it’s a quick source of energy; it helps the nerve tissues, primary energy source, fat and protein metabolism, and energy reserves in stored glycogen.
Examples: starch, sugars, breads, cereals, vegetables, fruits
c. Fats
macromolecules made of amino acids. Proteins have many
functions in the body. Some sources of proteins are whole-grain cereals, dark breads,rice, beans, and meat.
Proteins are:
-forming collagen and keratin
-transporting molecules in the blood
-quicken chemical reactions
b. Carbohydrates- molecules that contain carbon,hydrogen, and oxygen. Some sources of carbohydrates are sugars, breads, cereals, vegetables, and fruits
Carbohydrates are:
-quick source of energy
-best for the brain and nerve tissues
-there are simple and complex carbohydrate
c. Fats- type of lipid and usually come from animals. Sources can be lard and butter.
Fats are:
-needed for vitamin absorption
-creating cell lipids and steroids.
-excess energy is stored as fat in the human body macromolecules made of amino acids. Proteins have many
functions in the body. Some sources of proteins are whole-grain cereals, dark breads,rice, beans, and meat.
Proteins are:
-forming collagen and keratin
-transporting molecules in the blood
-quicken chemical reactions

Fats are:

-creating cell lipids and steroids.
-excess energy is stored as fat in the human body Description: a large group of compounds made of fatty acids
Functions: stores excess energy as fat in the human body, absorbs certain nutrients, maintains core body temperature
Examples: olive oil, avocado, nuts, soymilk, salmon, tuna, butter, red meat
