L.  aCytochemical localization of glycoproteins in the developing acrosome of ram spermatids.h[electronic resource]  c1978  aA cytochemical study at the ultrastructural level shows that several carbohydrate-containing substances are present in the acroplasm as soon as the proacosomic vesicles are synthesized. These substances fill the acrosomic granule during the early stages of spermiogenesis and then are sequentially avacuated from it during the cap phase of acrosome development. They attain their definitive location in the elongating spermatids' acrosomes throughout sequential phases. This results in the subdivision of the organelle into different regions according to their cytochemical affinities.  aBiochemistry  aConjugated proteins  aGlycoproteins  aReproduction  aSheep  aUltrastructure  aBioquímica  aFisiologia  aOvino  aReprodução  aSêmen  tJournal of Ultrastructure Researchgv. 65, n. 2, p. 173-181, Nov. 1978.
