Document Summary

Protein deficiency in infants: kwashiorkor: bloated stomach: absence of protein, is reversible if caught in time. Embodied in red meats, fish meat and milk. Enzymatic processes: process of the enzymes produced by the body, strings of amino acids, enzymes make material to help digest food. Eggs = excellent source of protein: egg-white: water is driven off, protein is visible, yolk: 50% water, 34% fat, 16% protein: will not firm up because of fat until 71 degrees celsius. Protein: nitrogen atom and a few other elements, occasionally sulfur (mostly, carbon, hydrogen, oxygen and nitrogen) Bonds that hold oxygen to nitrogen (join amino acids) are called peptide or amide bonds. Side groups: generally carbon atoms with a ring (sometimes) that individualize specific. Side containing nitrogen = amino end (from nh3 = ammonia_ R group = defines identity (can be any one of the 24 amino acids) Goes into body as intact protein, linked.
