Other nitrogen containing compounds Catecholamine: Dopamine‚ norepinephrine (noradrenaline) and epinephrine (adrenaline) are biologically active amines and are collectively called as Catecholamine. * Dopamine and norepinephrine functions as neurotransmitters. Outside the nervous system‚ norepinephrine and its methylated derivative‚ epinephrine regulates carbohydrate and lipid metabolism. They are released from storage vehicles in the adrenal medulla in response to stress (fright‚ exercise‚ cold

EXPERIMENT 5- A FISCHER ESTERIFICATION SYNTHESIS OF PEAR OIL One of the major uses of Esterification (C(=O)-C-R) is forming compounds with different odors which can be used to make different synthetic and natural flavorings. Using the chemical and physical properties of organic compounds‚ an ester was catalyzed from the reaction of a carboxylic acid with an alcohol‚ producing an odor similar to that of pear oil. The mechanism of this Fischer- Esterification process is outlined as follows:

and Applied Chemistry (IUPAC) General Form of IUPAC Nomenclature [branching substituent(s)] Root [Suffix] Rules: 1. Identify the longest continuous chain of carbon atoms. This chain determines the parent name (root) of the alkane. The parent suffix for alkanes is‚ not surprisingly‚ -ane. For chains of equal length‚ pick the one with the most substituents. (Note: I number all possibilities going from left to right – identify the longest chain) 2. Number the chain beginning at the

A carbohydrate is an organic compound that consists only of carbon‚ hydrogen‚ and oxygen‚ usually with a hydrogen:oxygen atom ratio of 2:1 (as in water); in other words‚ with the empirical formula Cm(H2O)n. The carbohydrates (saccharides) are divided into four chemical groupings: monosaccharides‚ disaccharides‚ oligosaccharides‚ and polysaccharides. In general‚ the monosaccharides and disaccharides‚ which are smaller (lower molecular weight) carbohydrates‚ are commonly referred to as sugars.

bone has been displaced from the point in where it should be. There are different types of fractures with the most common being hairline and compound. Hairline fractures are where there is a very fine line between the segments of the bone that appears when x- rayed. The bone segments will remain in alignment and the fracture may not go fully through. Compound fractures are also known as open fractures so if the skin has been pierced the outside air must be able to get to the fracture site without
