A rapid method to isolate soluble royal jelly proteins.
Soluble royal jelly (RJ) proteins (SRJPs) include the major RJ protein (MRJP) family, which contribute to the physiological actions of RJ. Although SRJPs are prepared using conventional methods involving dialysis and centrifugation, dialysis is a time-consuming process. We have therefore developed a simple method to isolate SRJPs from RJ. This new method produces 20-fold higher levels of SRJPs ...

متن کاملIdentification of a Novel Hypocholesterolemic Protein, Major Royal Jelly Protein 1, Derived from Royal Jelly
Royal jelly (RJ) intake lowers serum cholesterol levels in animals and humans, but the active component in RJ that lowers serum cholesterol level and its molecular mechanism are unclear. In this study, we set out to identify the bile acid-binding protein contained in RJ, because dietary bile acid-binding proteins including soybean protein and its peptide are effective in ameliorating hyperchole...
متن کاملAntihypertensive effect of peptides from royal jelly in spontaneously hypertensive rats.
We have shown that Protease N treated Royal Jelly (ProRJ) and peptides from ProRJ (Ile-Tyr (IY), Val-Tyr (VY), Ile-Val-Tyr (IVY)) inhibited angiotensin I-converting enzyme (ACE) activity and they have an antihypertensive effect in repeated oral administration for 28 d on spontaneously hypertensive rats (SHR). We investigated the contributive ratio of these peptides in ProRJ for antihypertensive...
متن کاملNatural peptides and proteins: potent tyrosinase inhibitors
Background and objectives: Tyrosinase is a copper containing oxidase which is crucial for controlling the production of melanin in creatures such as bacteria, fungi, plants and mammals. It is involved in the first two steps of melanin biosynthesis and leads to pigmentation and different types of cancer such as melanoma. Also, it is responsible for browning of fruits and vegetab...
