Hi matchette!!
The isolated molecule is a protein.
"Proteins:
Protein molecules contain carbon, hydrogen, oxygen, and nitrogen (plus
small amounts of iron, phosphorus, and sulfur). These elements combine
to form small
molecules called amino acids (carries amine group NH2). There are more
than 25 amino acids and amino acids link together in various
combinations to form proteins. Proteins make muscle, enzymes and many
other biochemical components of the animal body."
From "Basic Principles of Nutrition" at University of Nevada website:
http://www.unce.unr.edu/publications/EBPubs/EB-99-01_files/CHAP7.PDF
A protein molecule, can consist of more than a hundred amino-acid
monomers. Of all the possible amino acids, only 20 commonly occur in
life as we know it.
See the following definitions from "Glossary - Important terms related
to Molecular Biology" at "The Central Dogma" page from Collaborative
Electronic Learning Laboratory (CELL) website:
"·Amino Acid: The molecule which is the building block of proteins.
The 20 different amino acids which make up proteins all have a similar
structure, with an amino group, a carboxyl group and one of 20
different chemical side chains, all attached to a central carbon
atom...
·Peptide: A molecule comprised of multiple amino acids, bound by peptide bonds...
·Protein: Long polypeptide chains, often containing hundreds of amino
acids. Proteins can provide cell structure, act in cell motility, or
(as enzymes) possess catalytic activity."

Note that polypeptides are peptides with more than about 50 amino acid
units, then a protein molecule have hundreds of atoms.
Here is a list of the 20 amino acids found in living organisms on Earth:
