Document Summary

Minerals do not contain carbon, are essential for normal cell functions. They are necessary for proper uid balance, muscle and nerve function, and building bones and teeth. Antioxidants protect cells and tissues from damaged caused by highly reactive substances call free radicals, which have an incomplete outer electron shell and can thus oxidize (remove electrons from) other molecules. Polymers are formed by dehydration synthesis, in which a water molecule is removed and two monomers are joined. It helps protect blood vessels and decreases the risk of some cancers. Complex carbohydrates consist of many sugar polymers connected together. Essential amino acids cannot be synthesized by the body, they must come with food. The linear sequence of amino acids in a peptide chain is called the protein"s primary structure. Parts of the polypeptide chain can fold into one of the two types of secondary structures (alpha helix and beta pleated sheet). Tertiary structure comes from the interaction of side groups.

QUESTION 17

Most of us donât get enough Vitamin D since our sun exposure is limited in the northern states. Vitamin D is made in our body with the help of the ultraviolet rays from the sun being absorbed by the skin. Vitamin D is vital for our immune system, skeletal structure hormone balance, and other bodily functions.

In answering this question, the other way we can get Vitamin D is primarily by eating fruits.

The following explains information about antioxidants but one, which one is incorrect?

		We can't stop aging or get rid of the sun or live in a perfectly clean world but we can provide our body antioxidants that will fight free radicals.
		We know from our readings antioxidants are vitamin K and the minerals biotin and selenium.
		The foods with antioxidants are: all berries are great (strawberries, blackberries, blueberries, etc.), green leafy vegetables, carrots, tomatoes, dark chocolate, nuts, kidney beans and all beans, all herbs and foods mother nature provides us.
		The most effective compounds that can fight off free radicals are antioxidants, just as the name implies they counteract oxidation, the harmful reaction that takes place.

After working through the macromolecules in your friendâs extremely pale burrito, you look at her and think you might have an idea about what is going on. You ask Maria, âDo you usually eat like this?â âYup,â she says, âI love all the carbs, rice, and bread, as well as cheese. Sometimes I eat a piece of fruit or some carrot sticks. And energy drinks!â You then point out to your friend that she seems to be getting very little protein, a major class of macromolecules. But she is getting plenty of carbohydrates and lipids in the form of animal fats.

1. While your body can convert the monomers of macromolecules from one to the other, it has to have the raw materials in the form of the appropriate atoms. You explain to your friend that when she eats proteins, they are broken down into amino acids through the process of INSERT ANSWER and can then be rebuilt into new proteins through the process of INSERT ANSWER.

a. If your body does not take in protein, but only carbohydrates and lipids, what atoms will it be missing? Hint: There are two, and you can figure this out by comparing the structures of the monomers for proteins and carbohydrates as well as the basic structure of lipids. INSERT ANSWER

b. For the above atoms, how many electrons are in the outer shell? INSERT ANSWER

c. For the above atoms, what type of bond will they make within the amino acid monomer? INSERT ANSWER

d. Even if your friend does obtain the correct atoms, there are still a couple amino acids that your body cannot manufacture from scratch, but must be ingested. What are these amino acids? INSERT ANSWER

e.Why might a lack of protein or the wrong types of proteins lead to your friendâs fatigue? INSERT ANSWER
