2789994-7	1989	A wobble alignment of the O6alkG4.C9 base pair stablized by two hydrogen bonds, one between the amino group of C9 and N1 of O6alkG and the other between the amino group of O6alkG and N3 of C9, is tentatively proposed on the basis of the NOEs between the amino protons of C9 at the lesion site and the imino protons of flanking Watson-Crick base pairs.	Hydrogen	64-72	complement C9	Homo sapiens	111-130	
2372316-18	1990	The few NOE crosspeaks, pH dependence, and Cu2+ broadening of C9 1H signals indicate an isolated location accessible to solvent.	Hydrogen	65-67	complement C9	Homo sapiens	62-64	
8652545-6	1996	The energetic cost of removal of hydroxyl groups at the C-9 and C-14 positions (which structural studies indicate may participate in hydrogen-bonding interactions with the DNA) was approximately 1 kcal mol(-1).	Hydrogen	133-141	complement C9	Homo sapiens	56-59	
26400077-1	2015	The de novo design of a beta/gamma-peptidic foldamer motif has led to the discovery of an unprecedented 9/8-ribbon featuring an uninterrupted alternating C9/C8 hydrogen-bonding network.	Hydrogen	160-168	complement C9	Homo sapiens	154-159	
5639923-5	1968	The location of five of the six labelled hydrogen atoms at C-3, C-9, C-18 and C-19 (two) confirms that the mechanism of cyclization of squalene expected from the biogenetic isoprene rule is functioning in vivo.	Hydrogen	41-49	complement C9	Homo sapiens	64-67	
20564041-6	2010	The Gpn residue can adopt both C(7) (NH(i) CO(i)) and C(9) (CO(i-1) NH(i+1)) hydrogen bonds which are analogous to the C(5) and C(7) (gamma-turn) conformations at alpha-residues.	Hydrogen	77-85	complement C9	Homo sapiens	54-58	
24625033-6	2014	By comparing the oxysterol profile formed from 7-DHC and those formed from 8-DHC and 5,8(14)-dienol, products formed from abstraction of the hydrogen atoms at C-9 and C-14 (H-9 or H-14 mechanism) were clearly differentiated.	Hydrogen	141-149	complement C9	Homo sapiens	159-162
