Protein Functions
Proteins are the “workhorses” of the body and participate in many bodily functions. As we’ve
already discussed, proteins come in all sizes and shapes, and each is specifically structured
for its particular function. This page describes some of the important functions of proteins.
As you read through them, keep in mind that synthesis of all of these different proteins
requires adequate amounts of amino acids. As you can imagine, consuming a diet that is
deficient in protein and essential amino acids can impair many of the body’s functions. (More
on that later in the unit.)

Major types and functions of proteins are summarized in the table below, and the
subsequent sections of this page give more detail on each of them.
