Document Summary
The side chains of the amino acids ultimately help to determine the molecules" shapes & behaviours. Without these essential nutrients, the body cannot make the proteins it needs to do its work. Can only be replenished from foods: thus, a person must frequently eat the foods that provide them, recycling amino acids. In addition to making some amino acids the body breaks down proteins & reuses those amino acids: food proteins & body proteins are dismantled to liberate their component amino acids. Providing the body with the raw materials from which it can build the protein molecules it needs. Strand of protein does not remain a straight chain: The particular shapes of proteins enable them to perform different tasks in the body: Globular proteins are water soluble: such as some proteins of blood. Some proteins form hollow balls: can carry & store materials in their interior.
