Proteins are the most amazing group of molecules in the human body. They are incredibly complex chains of smaller molecules called amino acids. These strings of amino acids are then folded into complicated shapes to create millions of critical body components. The DNA double helix is a familiar example of a protein. Proteins are the basic quality of animal life. What sugars and carbohydrates are to plants, PROTEINS ARE TO ANIMALS.
WHAT ARE PROTEINS USED FOR?
a. Proteins include virtually all hormones such as insulin and progesterone.
b. Hemoglobin, a blood protein, carries oxygen to the cells.
c. Heat shock proteins help rebuild our cells after stress.
d. Transferrin and other transport proteins bind to minerals and carry them through the body.
e. Muscle protein is responsible for our ability to move.
f. Proteins such as RNA and DNA in the nuclei of our cells are responsible for the genetic code. g. Proteins are also essential for the body structure.
h. Bone forms in a protein matrix.
i. Other structural proteins include collagen, cartilage, elastin and keratin that forms the skin.
j. All enzymes are proteins. Thousands of enzymes facilitate every chemical reaction in the body.
k. Proteins may also be converted to sugar or fat to be used for fuel.
l. Adequate protein helps maintain a good energy level, stabilizes blood sugar, assists adrenal and thyroid activity, helps control weight and assists bowel function.
