초록
The histological and transmission electron microscopic studies revealed the synthesis activity predominantly in the hypopharyngeal glands of the nurse bees. The biochemical analysis of both, the hypopharyngeal gland extract and royal jelly elucidated unequivocally the proteins and lipids as the major constituents. Further the SDS-PAGE of hypopharyngeal gland extract showed about 17 protein bands, perhaps 14.10, 20.00, 29.00 and 43.00 kDa predominantly while that of royal jelly revealed only two protein bands of 29.00 and 43.00 kDa molecular weight suggesting them as the major royal jelly proteins (MRJP). The lipid profile of royal jelly consists of triglycerides, cholesterol, HDL, LDL and VLDL.
