Document Summary

Chapters 5, 6, & 7: composed of amino acids (aa, 20 found in nature, 9 are essential, composed of carbon, hydrogen, oxygen, and nitrogen and sometimes sulfur. Nitrogen = key element in plant growth, plants ability to produce protein depends on this. Legumes can get around this limitation though because they fix nitrogen: fix nitrogen: they pull nitrogen out of the air, this is why legumes are higher in protein that any other plant source. Animals can"t synthesize amino acids from nitrogen, so they are dependent on plant proteins. In the end, the nitrogen will return to the soil. Nitrogen composes bout 78% of the air we breathe. Amino acids: composed of carbon, hydrogen, oxygen, nitrogen, and in few cases sulfur, nitrogen is present in the amino acid as part of a chemical group called amine, carboxyl group is also involved.
