  2. Protein secondary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_secondary_structure

    The Dictionary of Protein Secondary Structure, in short DSSP, is commonly used to describe the protein secondary structure with single letter codes. The secondary structure is assigned based on hydrogen bonding patterns as those initially proposed by Pauling et al. in 1951 (before any protein structure had ever been experimentally determined).

  3. Glycolipid - Wikipedia

    en.wikipedia.org/wiki/Glycolipid

    Glycolipid. Glycolipids are lipids with a carbohydrate attached by a glycosidic (covalent) bond. [1] Their role is to maintain the stability of the cell membrane and to facilitate cellular recognition, which is crucial to the immune response and in the connections that allow cells to connect to one another to form tissues. [2]

  4. Protein primary structure - Wikipedia

    en.wikipedia.org/wiki/Protein_primary_structure

    However, proteins can become cross-linked, most commonly by disulfide bonds, and the primary structure also requires specifying the cross-linking atoms, e.g., specifying the cysteines involved in the protein's disulfide bonds. Other crosslinks include desmosine.

  5. Seniority (financial) - Wikipedia

    en.wikipedia.org/wiki/Seniority_(financial)

    Bonds that have the same seniority in a company's capital structure are described as being pari passu. Preferred stock is senior to common stock in a sale when preferred shareholders must receive back their preference , typically their original investment amount, before the common shareholders receive anything.

  6. Cooperative binding - Wikipedia

    en.wikipedia.org/wiki/Cooperative_binding

    The first description of cooperative binding to a multi-site protein was developed by A.V. Hill. [4] Drawing on observations of oxygen binding to hemoglobin and the idea that cooperativity arose from the aggregation of hemoglobin molecules, each one binding one oxygen molecule, Hill suggested a phenomenological equation that has since been named after him:

  7. Phosphodiester bond - Wikipedia

    en.wikipedia.org/wiki/Phosphodiester_bond

    Specifically, it is the phosphodiester bonds that link the 3' carbon atom of one sugar molecule and the 5' carbon atom of another (hence the name 3', 5' phosphodiester linkage used with reference to this kind of bond in DNA and RNA chains). [3] The involved saccharide groups are deoxyribose in DNA and ribose in RNA.

  8. Subordinated debt - Wikipedia

    en.wikipedia.org/wiki/Subordinated_debt

    Subordinated debt has a lower priority than other bonds of the issuer in case of liquidation during bankruptcy, and ranks below: the liquidator, government tax authorities and senior debt holders in the hierarchy of creditors. Debt instruments with the lowest seniority are known as subordinated debt instruments. [1] [2]

  9. United States Savings Bonds - Wikipedia

    en.wikipedia.org/wiki/United_States_Savings_Bonds

    The bond will continue to earn the fixed rate for 10 more years. All interest is paid when the holder cashes the bond. For bonds issued before May 2005, the interest rate was an adjustable rate recomputed every six months at 90% of the average five-year Treasury yield for the preceding six months.
