Biscuithead & the Biscuit Badgers - The Amino Acids Song

〈Intro〉
When it comes to amino acids
There are basically four types
Acidic, basic, nonpolar, 'n' polar

〈Verse 1〉
(Nonpolar)
Glycine, alanine, valine, leucine
Isoleucine, methionine
Phenylalanine, tryptophan, and proline

〈Verse 2〉
(Polar)
Serine, threonine, cysteine, 'n' tyrosine
Asparagine, glutamine
And the other five monomers are electrically charged (electrically charged, babe!)

〈Chorus〉
They make structural proteins (storage proteins)
Transport proteins (hormonal proteins)
Receptor proteins (contractor proteins)
Defensor proteins (enzymatic proteins)
Structural proteins (storage proteins)
Transport proteins (hormonal proteins)
Receptor proteins (contractor proteins)
Defensor proteins (enzymatic proteins)
〈Instrumental Break〉

〈Verse 3〉
The carboxyl groups on the side chain
Identify two as acidic
Aspartic acid and glutamic acid
The final three are basic, if you know what I mean
Lysine, arginine, and histidine
Amino groups on the side chain
Mean that they are positively charged

〈Chorus〉
They make structural proteins (storage proteins)
Transport proteins (hormonal proteins)
Receptor proteins (contractor proteins)
Defensor proteins (enzymatic proteins)
They make structural proteins (storage proteins)
Transport proteins (hormonal proteins)
Receptor proteins (contractor proteins)
Defensor proteins (enzymatic proteins)

〈Instrumental Break〉

〈Bridge〉
Glycine, alanine, valine, leucine
Isoleucine, methionine
Phenylalanine, tryptophan, and proline
Serine and threonine
And cysteine and tyrosine
Asparagine, glutamine
Aspartic acid and glutamic acid
〈Chorus〉
Glycine, alanine, valine, leucine (structural proteins, storage proteins)
Isoleucine, methionine (transport proteins, hormonal proteins)
Phenylalanine, tryptophan (receptor proteins, contractor proteins)
And proline (defensor proteins, enzymatic proteins)
Serine and threonine (structural proteins, storage proteins)
And cysteine and tyrosine (transport proteins, hormonal proteins)
Asparagine, glutamine (receptor proteins, contractor proteins)
Aspartic acid and glutamic acid (defensor proteins, enzymatic proteins)

〈Outro〉
Glycine, alanine, valine, leucine (structural proteins, storage proteins)

And proline (defensor proteins, huh!)
