Document Summary
Whats wrong with eating too much protein: we"d have positive nitrogen balance - which would cause ammonia to be in our bodies, ammonia is toxic and would need to be excreted as urea. The chemist"s view of proteins: contain c, h, o, & n, all 20-22 amino acids: Unique side group: essential (9) and non- essential (11-13) Tuesday, january 30, 2018: 4 9 amino acids is called an oligopeptide; 10 or more amino acids is called polypeptide, most functional proteins in our bodies are polypeptides. Sequence of amino acids: secondary structure. Determined by weak electrical attractions within chain. Results in twisting or folding of protein. Subunits within a given protein which can have di erent structure and function. Protein denaturation: disturbs their stability, denatured means: they uncoil and lose their shape. Loss of functional ability: accomplished by: Protein absorption: amino acids are transported into intestinal cells.
