Benedicts test is a test that checks for aldehydes with adjacent hydroxyl groups. The patient
being tested consumes sugar that is classified as reducing sugars (a carbohydrate that reduces
from Cu2+ to Cu+). Since the patients diet consists of sugar
Compounds are more than one element bonded together and may not keep the characteristics of
the elements that are bonded together. Elements are the most basic substances that exist and they
cannot be broken down into other substances. Two examples of comp

Assignment 2: Problem Statement
By Week 8, Day 5, respond to the problem statement assigned to you for this week.
A middle-aged man has been diagnosed as being at high-risk of developing Coronary Artery
State the chemical comp
Alkenes are hydrocarbons where the carbons are connected together through a double bond,
whereas the alkynes are hydrocarbons where the carbons are connected together through triple
bonds. The triple bond is much stronger than the double bond and would re
Radiation is very commonly used in medicine in this day and age. We see radiation used in
something as simple as a routine dentist appointment. Various uses of radioactivity in healthcare
are the use of x-ray machines, CT scans, MRIs, PET scans, and radia
A buffer helps to resist a change in pH. It consists of a weak acid and an equally weak base.
Acting together, this solution acts to neutralize any acid or base added to a system.
As we learned in the course lesson this week, most acids and bases are weak
The two important classes of catalysts are homogeneous and heterogeneous. The key to
differentiating these two reactions is in the name. We know that homo means like or the same
while hetero means different. So a homogeneous catalysis would be when the ca
The sterol present in this case is cholesterol. The chemical composition of cholesterol is
C27H46O. Excess cholesterol can cause plaque buildup or lipid deposits in ones arteries. If the
plaque builds up is the arteries of the heart this can cause th

Genetic mutations occur when there is an alteration in the genes of ones DNA causing
malfunctions. The change in the DNA can affect the resulting proteins ability to function
properly. Gene mutation generally occurs as a result of errors during the r
Cells consist of a large amount of protein. Roughly half of a cells dry weight consists of protein.
Amino acids are the molecular building blocks of proteins. There are twenty amino acids that are
used to build the proteins in the human body, only ha
Genes are the genetic material passed from parent to child, and make up DNA. Deoxyribonucleic
acid (DNA) and Ribonucleic acid (RNA) are both forms of genetic material inside of a cell.
DNA is a chemical inside of a cells nucleus that communicates genetic
Discussion Question 1
Identify the two important classes of catalysts. Analyze the chemical reactions that take place
when a biological catalyst combines with a reactant (substrate) to form an unstable intermediate.
The two important classes of catalysts
Week 2 Assignment 2
Determine the amount of sodium that has been actually added, in grams.
From the problem I learned that the student used 6 teaspoons of salt and that each teaspoons of
salt contains 2,300 mg of sodium.
2,300 mg of salt x 6 teaspoons of
Abundance and Sources
Nitrous oxide is produced from both natural and human-related sources Natural sources of nitrous oxide are primarily a result of bacterial breakdown of nitrogen in soils and in oceans Human sources of nitrous oxide include agricult
