Document Summary

The brain utilises about 20% of the body"s oxygen supply (only 2% of its weight). Any interruption of the oxygen supply can result in weakening, permanent damage, or death of brain cells in minutes (cpr). Glucose (major atp source) deficiency may produce mental confusion, dizziness, convulsions, and unconsciousness. The bbb protects brain cells from harmful substances and pathogens by serving as a selective barrier to prevent passage of many substances from the blood into the brain. The bbb can prevent the entry of therapeutic drugs. Injury to the brain may cause a breakdown of the bbb, permitting the passage of normally restricted substances into the brain tissue. Csf is a clear liquid (~150ml) that protects the brain and spinal cord against chemical and physical injuries (shock absorber) and it carries oxygen, glucose, and other important substances from the blood to nervous tissue cells. Classified as a transcellular fluid made in the brain from plasma.

I am needing to know how these bath temperatures are obtained, Ihad them written down in my lecture/lab notes but I lost the entirebinder and could not remember the conditions necessary for the bathtemps. I striking suspicion that these may turn up on my laboratoryexam, anyways thanks in advance :-)

-78^o C

-95^oC

Below are 2 different compounds that I need help identifying. I have attached the NMR and IR spectra that we gathered. We have a couple ideas of what they could be and made marks on the spectra but would like an expert's help with finalizing them. The second NMR spectra is supposed to have a peak around 12-14 for a carboxylic acid but did not show up on ours and it was confirmed that it should be there. There aren't any base peaks either, we had to go into this blind. Thank you so much!
