What Is the Building Block of a Protein?
Proteins are essential molecules that play a crucial role in nearly every biological process. But what exactly makes up a protein? The fundamental building blocks of proteins are amino acids. These small organic molecules link together in long chains to form proteins, much like individual beads in a necklace.
There are 20 different amino acids, each with a unique structure and function. They join together through peptide bonds, forming polypeptides that fold into complex shapes to create functional proteins. These proteins are responsible for various bodily functions, including enzyme activity, cell signaling, and structural support. Without amino acids, life as we know it wouldn’t exist!
