Triterpenoid
Triterpenoid is a byproduct from squalene 2,3-oxide decomposition. Squalene is a precursor to sterol biosynthesis. Terpenes are derived biosynthetically from units of isoprene, which has the molecular formula C5H8. The basic molecular formulas of terpenes are multiples of that, (C5H8)n where n is the number of linked isoprene units. This is called the isoprene rule or the C5 rule. The isoprene units may be linked together "head to tail" to form linear chains or they may can be arranged to form rings. One can consider the isoprene unit as one of natures preferred building blocks. [HMDB] Triterpenoid is a byproduct from squalene 2,3-oxide decomposition.

Arbekacin
Arbekacin is only found in individuals that have used or taken this drug. It is an semisynthetic aminoglycoside antibiotic. Often used for treatment of multi-resistant bacterial infection such as methicillin-resistant Staphylococcus aureus (MRSA). Amikacin is also nephrotoxic and ototoxic.Aminoglycosides, such as Arbekacin, inhibit protein synthesis in susceptible bacteria by irreversibly binding to bacterial 30S and 16S ribosomal subunits. Specifically Arbekacin binds to four nucleotides of 16S rRNA and a single amino acid of protein S12. This interferes with decoding site in the vicinity of nucleotide 1400 in 16S rRNA of 30S subunit. This region interacts with the wobble base in the anticodon of tRNA. This leads to misreading of mRNA so incorrect amino acids are inserted into the polypeptide leading to nonfunctional or toxic peptides and the breakup of polysomes into nonfunctional monosomes.
