I don't think I came across this when I did biology...

But there are some basic things that you could logically derive from it:

  • Gramicidin A is an antibiotic compound
  • You know that 'Gram-positive/negative' are types of bacteria - so 'gramicide' is to kill Gram-positive bacteria.

As per Wikipedia, Gramicidin itself is a heterogeneous (consisting of different types of Gramicidins - A, B and C (these are collectively known as Gramicidin D)) antibiotic. Gramicidin is protein in nature, as Gramicidin D is made up of 15 amino acids.

It is an integral membrane protein (a protein molecule that is permanently attached to the biological membrane).

But yeah, don't worry about it.
