Developing queen larvae surrounded by royal jelly. Royal jelly is a honey bee secretion that is used in the nutrition of larvae and adult queens. [1] It is secreted from the glands in the hypopharynx of nurse bees, and fed to all larvae in the colony, regardless of sex or caste. [2] Queen larva in a cell on a frame with bees
He found two proteins as potential markers for freshness of royal jelly protein and named them royal jelly proteins (RJP-1 and RJP-2). RJP-1 was a 57-kDa monomer which is a subunit of a larger complex (oligomer). [5] In 2011, Kamakura claimed that RJP-1 is the main protein for controlling larval development that distinguishes the queen from ...
First, he collected royal jelly from a group of honey bee larvae and purified the results by reverse phase, high-performance liquid chromatography. This purified royal jelly showed antimicrobial activity against different bacteria. [2] So far, four peptides have been found in this family, each one containing the carboxamide C-terminal.
Queen honey bees are created when worker bees feed a single female larva an exclusive diet of a food called "royal jelly". [85] [88] Queens are produced in oversized cells and develop in only 16 days; they differ in physiology, morphology, and behavior from worker bees. In addition to the greater size of the queen, she has a functional set of ...
Royal jelly is a honey bee secretion used to nourish the larvae and queen. [71] It is marketed for its alleged but unsupported claims of health benefits. [ 72 ] [ 73 ] On the other hand, it may cause severe allergic reactions in some individuals.
Queen bee acid (10-hydroxy-2-decenoic acid or 10-HDA) is a fatty acid found in royal jelly. [1] [2] [3] Queen bee acid is being investigated for its potential pharmacological activities. It promotes neurogenesis of neural stem/progenitor cells (cells capable of differentiating into neurons, astrocytes, or oligodendrocytes) in vitro. [4]

An early study also determined the cellular basis of the discrete caste morphology of A. mellifera. Queens arise when workers in a colony selectively feed chosen larvae royal jelly. The caste differentiation occurs through an epigenetic process; non-heritable factors contributing to gene expression.
