Here we have showed that, in mouse macrophages, H2 exhibited substantial inhibitory activity against LPS-initiated NLRP3 inflammasome activation by scavenging mtROS. Due to the unique molecular structure, H2 can easily target the mitochondria, suggesting that H2 is a potential antagonist of mtROS-dependent NLRP3 inflammasome activation. A secondary (2º) hydrogen is a hydrogen atom residing on a secondary carbon in an organic species.. eg: see also primary hydrogen, tertiary hydrogen Hydrogen bonding confers rigidity to the protein structure and specificity to intermolecular interactions.

The Lewis structure of a water molecule then looks like O H H water Hydrogen peroxide is a different compond of hydrogen and oxygen, with chemical formula H 2O 2. Finally, Pauling predicted that hydrogen bonds must be able to stabilize the folding of the peptide backbone. When a hydrogen atom is bonded to Incidentally, there are the same number on the third structure. Amino acids in proteins don’t lie in linear chains. For more information contact us at info@libretexts.org or check out our status page at https://status.libretexts.org. Two secondary structures, the alpha helix and the beta pleated sheet, fulfill these criteria well (see Figure ). thank u. Within the long protein chains there are regions in which the chains are organised into regular structures known as alpha-helices (alpha-helixes) and beta-pleated sheets. Proteins are the organic molecules made up of amino acids. For example, the bond line notation for propane is. The hydrogen that will be easiest to remove is indicated in the figure with the arrow.When a hydrogen atom is bonded to secondary carbon, It is called secondary hydrogen.
