1): pathway 1 - by addition to ceramide synthesized de novo by acylation of sphinganine; pathway 2 - addition to ceramide synthesized from recycled sphingosine; and pathway 3 - by addition to GSLs that recycle from endosomes to the Golgi apparatus.
In general, cellulose has been first functionalized by aryl carbamoylation or acylation, and the as-synthesized derivatives have been then coated or covalently immobilized on the silica gel to obtain the chiral separation materials [9, 10].
The Friedel-Crafts alkylation and acylation of aromatic rings, removal of tert-butyl groups from phenols, and the well-known ZieglerNatta polymerization reactions are some examples where the aluminum trichloride acts as catalyst.
Dietary linoleic acid influences desaturation and acylation of deuterium-labeled linoleic and linolenic acids in young adult males.
Adiponectin, acylation stimulating protein and complement C3 are altered in obesity in very young children.
In the area of nerve agent chemistry, there are very good articles on the separation of enantiomers with different activities by gas chromatography with chiral stationary phases, and a demonstration of the influence of chirality of organophosphate esters on the inhibition of acetylcholinesterase (AChE) and "neuropathy target esterase (NTE)." Although the inhibition of AChE by organophosphorus compounds is fairly well known, it is not generally appreciated that such compounds can also induce a delayed polyneuropathy by acylation and subsequent modification of the structure of NTE.
When R1 = H, DHPMs 4 could be alkylated at [N.sub.1] [29] whereas the formylation or acylation of [N.sub.3] of 4 furnishes the [N.sub.3]-formylated or [N.sub.3] acylated derivatives [30].

Recently, we described the preparation of novel polyfaryl ether ketone)s containing amide linkages in main chains by the electrophilic Friedel-Crafts acylation copolycondensation, the resulting copolymers with low content of amide linkages had not only much higher [T.sub.g]s than the conventional PEEK and PEKK due to the existence of intermolecular hydrogen bonding, but also moderate [T.sub.m]s, which are suitable for melt processing, but the resistance to organic solvents and the thermal decomposition temperature ([T.sub.d]) decreased with the introduction of amide linkages [23-26].
