Skin is a barrier that serves as one of the body's first lines of defense against harmful microbes. Specialized immune cells within skin tissue help to fight invading organisms. Past work by an NIH research team showed that commensals can help the body's immune cells fight disease-causing microbes.

Well, basically, everything is made of atoms and cells. Those are youre building blocks for every life unit. The subunits of proteins are amino acids. These acids combine (in different combinations) to form different proteins.
The subunits of starch are carbohydrates. They build to form molecules of starch.
The
subunits of DNA are nucleic acids. These mix with other things to form
DNA. It is like the protein where different combinations create
different DNA strands/molecules.
