Proteins

Proteins:

     Proteins are one of the four macromolecules we are learning about in biology and is a familiar word to most people. The monomer or the subunit of proteins are amino acids. Peptide bonds connect the amino acids to form the polymers of proteins. Examples of these polymers would be dairy products, meats, beans, and more.

     Most people believe that the function of proteins are to provide energy which is why people usually eat lots of proteins or drink proteins shakes when they work out a lot. However,this is not true. The main functions of proteins are building muscle, growing hair, increasing the reaction speed of enzymes, and allowing hemoglobin to carry oxygen in the blood. Without proteins our bodies would eventually stop building muscle and begin to break down tissue. 

     Proteins relate to the food pyramid by providing us with what is necessary for our bodies to thrive. According to the food pyramid, it is best to have two to three servings of protein per day. Having the sufficient amount of proteins daily is important to stay healthy, strong and able to function properly and efficiently. The percentage of protein in your food consumption should be between 10-35%.

      Foods such as dairy products, beans, eggs, and meats supply proteins.
