Hydrogen bonding is that the interaction involving a atom placed between a combine of alternative atoms having a high affinity for electrons; such a bond is weaker than an bond or bond however stronger than van der Waals forces. element bonds will exist between atoms in numerous molecul...
What is hydrogen bonding and how might hydrogen bonding be used to explain the substantial difference in boiling between ethanol CH3CH2OH (grain alcohol) and dimethyl ether (CH3OCH3)? What are the properties of water such as type of bonding and boiling point?
The original examples of hydrogen bonding were found to involve the electronegative atoms F, O, or N. The current IUPAC definition given in the ‘Gold Book’ still specifically mentions these atoms, although it adds a caveat suggesting that the phenomenon is not limited to these atoms … Clearl...
median eminence10. GnRH then acts on gonadotrope cells in the anterior pituitary to trigger secretion of the gonadotropins; luteinizing hormone (LH) and follicle-stimulating hormone (FSH). LH and FSH in turn regulate sex hormone production (i.e., estradiol in females and testosterone in males)...

Generally, various secondary structure types have different tendencies to engage in stable hydrogen bonding, with loops being less hydrogen bonded than helices and sheets which are, by definition, stabilized by amide hydrogen bonding. In the Pab1 structure, the hydrophobic sheets tend to be the most...
