1. The sequence of amino acids determines the ______________ of the protein. The _____________ of a protein is important because it influences the function. a. If the sequence of amino acids is wrong (faulty DNA code) a defective protein is made which can be deadly. Example: Sickle Cell Anemia
Shape/Shape
1. A food ____________ is an inflammatory response that results when the immune system reacts inappropriately to an allergen in a food. Protein is commonly the allergen.
allergy
1. By helping to maintain fluid balance, proteins prevent ___________, which is the accumulation of fluids in tissues. The force of blood pressure moves fluid out of the bloodstream while blood proteins counteract the effects by attracting the fluid back into the bloodstream.

High intake of red meat and processed meats increase risk of chronic disease and cancer risk. High-protein diets may lead to high urinary ____________ loss. This may increase the risk of ________________, a condition characterized by thin bones that fracture easily. Dehydration is also a risk of excess protein intake.
Calcium ; Osteoporis
1. Proteins also help maintain acid-base balance by acting as a _________________. These proteins will bind to H+ if blood is too acidic, release H+ if blood is too basic.
buffer
1. A ________________ is a chemical attraction that connects two amino acids together.
peptide bond
1. Protein digestion begins in the _____________. Hydrochloric acid denatures food proteins and activates pepsin, an enzyme that breaks down proteins into smaller polypeptides. Enzymes release by the pancreas and small intestine break down shortened peptides into dipeptides and tripeptides. Enzymes from the microvilli will break down proteins into single amino acids which are absorbed into the blood stream and delivered to the liver.
stomach
Deamination
the removal of the nitrogen-containing group from an amino acid.
