Document Summary
Working proteins include enzymes, antibodies, transport vehicles, hormones and oxygen carriers. Structural proteins: tendons and ligaments, scars, fibres of muscles, hair, nails. Amino acids are the building blocks of protein shakes. Alcohol, acids, heavy metal, acids and bases. Single carbon atom with one amine group and a side chain: side chain make the amino acids differ in size, shape and electrical charge. When human body cannot make enough amino acids for their daily needs. Can be replenished from foods (10-35% - protein) Body is also able to recycle amino acids. Breaking apart proteins after digestion after completing their cellular work. Allows for emergency supply of amino acids for fuel, glucose or protein deprivation. Uses most dispensable muscles first and leaving the organs and heart protein until dire need. Amino acids with electrically charged side chains attract water outside of protein structure. Neutral amino acids repel water attracts one another.
