B-type pattern

Brown et al.238 reported that starch granules from 18- and 24-day-old su2 kernels are weakly birefringent and have an A-type x-ray pattern (Table 3.4), in contrast to the B-type pattern reported for starch granules from mature su2 kernels.360,387 The BEPT of su2 granules is lower than that of normal granules (Table 3.4).359,388 Based... [Pg.56]

Amylodextrins from waxy-maize starch (A type) and potato starch (B type) retain the same diffraction pattern as that of the parent starch. On separation of a starch to give an amylodextrin, the... [Pg.393]

Proanthocyanidins of the B-type are characterized by singly linked flavanyl units, usually between C-4 of the chain-extension unit and C-6 or C-8 of the chain-terminating moiety. They are classified according to the hydroxylation pattern of the chain-extension units (see T able 11.1). [Pg.568]

Starch granules from ae kernels have a much higher BEPT than normal or the other mutants (Table 3.4). Also, based on 14 genotypes studied, the B-type x-ray diffraction pattern appears to be unique to ae and ae -containing genotypes (Table 3.4). [Pg.52]
