A more common pronunciation of "peptidoglycan". Peptidoglycan, also known as murein, is a polymer that forms a homogeneous layer lying outside the plasma membrane and is only found in eubacteria (note: archaea have pseudopeptidoglycan). It serves a structural role in the cell walls of bacteria, giving them shape and strength and counteracting the osmotic pressure of the cytoplasm. It is also involved in the binary fission (reproduction) of the bacterial cell. Peptidoglycan is a target for many antibacterial drugs, such as penicillin, which works by interfering with the formation of the peptidoglycan layer, specifically the crosslinking enzyme transpeptidase.
The peptidoglycan layer is thicker in Gram-positive bacteria (20 to 80 nm) than in Gram-negative bacteria (7 to 8 nm), with the attachment of the S-layer. It forms around 90% of the dry weight of Gram-positive bacteria but only 10% of that of Gram-negative bacteria.
The peptidoglycan layer in the bacterial cell wall is a crystal lattice structure formed from linear chains of two alternating amino sugars, namely N-acetyl glucosamine (GlcNAc) and N-acetyl muramic acid (MurNAc). Each MurNAc is attached to a short (4 to 5 residues) amino acid chain. Cross-links between amino acids in different linear amino sugar chains by an enzyme known as transpeptidase result in a 3-dimensional layer that is strong and rigid. The specific amino acid sequence and molecular structure vary with the bacterial species.
Pet-The-Bunny was originally created by a pair of genius biology students while they were expressing themselves in a PowerPoint presentation.
note: there was originally a third student, but he was unwilling to participate and therefore caused a drop in the team's score.
"Yeah, inside a cell wall is proteins and pepti- perptidoil- Pet-The-Bunny"

an expression used to euphemistically describe sexual activity-- of any sort
when a guy says it to a girl, it's meant to sound cute, sweet and boyishly charming--and when he uses the term in front of his guy friends it means he really likes the gal he's discussing and won't even use crass talk about sex with her
girls don't use the term with each other except jokingly, as if were so stuuupid to say that, but whatever, it's cute, and they know if a guy's using it he's at least trying to be suave
"hey c'mon Tymara, can't we pleese just go an pet the pony fos a leetle while? pleese? the pony been alone today, he miss you sooooo bad..."

Cushion Pets are a cheap nock-off of pillow pets. cushion pets are sold 20 dollars more even though they are not brand name. You can tell it is a cushion pet when there are minor flaws like the nose is different.
That pillow pet is so cool!, No it's a Cushion Pet.

Pillows that can be unfolded into stuffed animals. Possibly the dumbest fucking thing you could ever buy a kid.
Santa gave my 7 year old cousin 2 pillow pets for Christmas. He presumed to sit in a corner and cry for 6 hours.

When things get out of hand at a Jenny Craig meeting.
I don't really like the meal plans, but I'll stick with any diet that involves this much heavy petting.

A way to pronounce peptidoglycan. I first used this term when unable to pronounce peptidoglycan during a powerpoint presentation.
As you can see, Pet The Bunny can be found only in plant cells only.
