What does Deacylated mean?
: to remove an acyl group from (a compound)
What is Deacetylated chitin?
Chitin deacetylases, occurring in marine bacteria, several fungi and a few insects, catalyze the deacetylation of chitin, a structural biopolymer found in countless forms of marine life, fungal cell and spore walls as well as insect cuticle and peritrophic matrices.
What does acyl stand for?
Definition of acyl : a radical RCO− derived usually from an organic acid by removal of the hydroxyl from all acid groups —often used in combination.
Why is chitin Deacetylated?
In its native form, chitin displays a poor reactivity and solubility in most solvents due to its extensive hydrogen bonding. This can be overcome by deacetylation.
What is the function of acyl group?
An acyl group is a functional group with formula RCO- where R is bound to the carbon atom with a single bond. Typically the acyl group is attached to a larger molecule such that the carbon and oxygen atoms are joined by a double bond. Acyl groups are formed when one or more hydroxyl groups are removed from an oxoacid.
What is the difference between acyl and ketone?
The acetyl group requires a methyl group on one side (a carbon with three hydrogens) of the carbonyl, and has no requirement for the other side. The ketone requires carbons on both sides of the carbonyl, but has no requirement as to what is attached to those carbons.
What is the P site and a site?
The P-site (for peptidyl) is the second binding site for tRNA in the ribosome. The other two sites are the A-site (aminoacyl), which is the first binding site in the ribosome, and the E-site (exit), the third. During protein translation, the P-site holds the tRNA which is linked to the growing polypeptide chain.
What is chitin function?
Chitin is one of the most important biopolymers in nature. It is mainly produced by fungi, arthropods and nematodes. In insects, it functions as scaffold material, supporting the cuticles of the epidermis and trachea as well as the peritrophic matrices lining the gut epithelium.
