The first half of module seven discussed protein digestion‚ absorption‚ and metabolism; while the second half focused on pathological stress and kidney disease. Protein digestion occurs in the stomach and small intestine. When a protein reaches the stomach it is denatured by hydrochloric acid. Once the protein is digested pepsin breaks apart the denatured protein into peptides. Peptides move into the small intestine where they encounter an enzyme that digest the peptides into di- or tripeptides‚

DNA: DNA is a double-stranded nucleic acid that contains the genetic information for cell growth‚ division‚ and function. DNA‚ or deoxyribonucleic acid‚ is the hereditary material in humans and almost all other organisms. Most DNA is located in the cell nucleus but a small amount of DNA can also be found in the mitochondria .The information in DNA is stored as a code made up of four nitrogen bases which are adenine (A)‚ guanine (G)‚ cytosine (C)‚ and thymine (T). these nitrogen bases are bind with
