Stress tests are tests performed by a doctor and/or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle).
The four types of organic compounds are carbohydrates, lipids, proteins and nucleic acids. Organic molecules contain the elements carbon and hydrogen, and they are found and made in living things. Keep Learning.
A bit of artwork based on polymer molecules. The second class of organic molecules are called lipids. Fats and oils are included in this class of molecules. These have a fairly simple structure, starting with the 3-carbon glycerol molecule.Each carbon picks up a bit called a fatty acid, which can be short or fairly long, and then it's a lipid molecule.ore on organic molecules. An article about organic molecules that shows how tricky it is to show 3-dimensional molecules in a 2-dimensional image. Organic molecules found on planet circling another star (video).
