Actually, solid-phase extraction is used not only as a rough preliminary fractionation procedure. Prieto et al. described the complete fractionation of the total lipids from wheat into eight neutral lipid, two glycolipid, and four phospholipid classes in addition to PC and LPC, TV-acyl PE and A-acyl LPE were detected (37). However, two separate stationary phases (silica and aminopropyl) as well as seven different mobile phases were needed. Moreover, 14% crosscontamination of PC and LPC was observed, and the recovery of the phospholipids was limited to about 85%. Hence, SPE is a rapid and efficient technique for preliminary fractionation, but loses its advantages if more complex separations are tried. 

In contrast to PDC from wheat germ and PDCS.c., which produce an enantiomeric excess of about 50% of (R)-( + )-acetoin [26,27,63,162], PDCZ.m. synthesizes predominantly the (S)-( — )-acetoin [153], Whereas the acylation of aromatic aldehydes by either PDC from yeast or Z. mobilis gives exclusively the (P)-acyloins [149,154,163,164],...

Truncated structures of sialic acids show the moieties required for binding to various sialic acid-specific lectins. LFA is Limaxfiavus agglutinin [231] and WGA is wheat germ agglutinin [5]. The binding importance of sialic acid C-4 and C-7 hydroxyls for MAG has not yet been determined. R indicates that LFA tolerates a variety of equatorial bulky substituents on the C-5 W-acyl group of sialic acids... 

It is now evident that acylation with anhydrides (such as acetic and succinic anhydrides) and with lactones (such as -propiolactone) is being proposed (< ) for improving the solubility of soy protein isolates at acidic pH, particularly for the preparation of coffee whiteners. Moreover, this chemical modification has been evaluated for altering the food-use properties of several milk proteins (40), egg protein (41), wheat protein (42), fish protein (43), and single-cell protein (44). 

Pyridazinone effects on phospholipids also provide information relative to phospholipid biosynthesis. The similarity in fatty acid composition of PC and PE in the absence of BASF 13 338 and their equivalent response to treatment suggest that the biosynthesis of phospholipids in wheat roots is not specific with respect to acyl chains. 

The A -acyl hexahydro derivatives (44), together with a number of smaller-ring analogues, have received patent protection as agrochemical fungicides, providing essentially complete control of Piricularia oryzae at ca. 500 ppm and of Puccinia recondita at ca. 200 ppm, with no damage to rice or wheat.
