  2. Adenosine triphosphate - Wikipedia

    en.wikipedia.org/wiki/Adenosine_triphosphate

    Adenosine triphosphate (ATP) is a nucleoside triphosphate [2] that provides energy to drive and support many processes in living cells, such as muscle contraction, nerve impulse propagation, and chemical synthesis. Found in all known forms of life, it is often referred to as the "molecular unit of currency" for intracellular energy transfer. [3]

  3. Tannin - Wikipedia

    en.wikipedia.org/wiki/Tannin

    Representative chemical structure of a tannic acid, a type of tannin Tannin powder (mixture of compounds) A bottle of tannic acid solution in water. Tannins (or tannoids) are a class of astringent, polyphenolic biomolecules that bind to and precipitate proteins and various other organic compounds including amino acids and alkaloids.

  4. Biochemistry - Wikipedia

    en.wikipedia.org/wiki/Biochemistry

    Biochemistry or biological chemistry is the study of chemical processes within and relating to living organisms. [1] A sub-discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology, and metabolism. Over the last decades of the 20th century, biochemistry has become successful at ...

  5. Secondary metabolite - Wikipedia

    en.wikipedia.org/wiki/Secondary_metabolite

    Secondary metabolite. Structural formula for the amino acid pipecolic acid, which contrary to other amino acids is not used as a building block in proteins. In some plants, pipecolic acid act as a defense compound against microorganisms. [1] Because of its limited presence, pipecolic acid is considered a secondary metabolite.

  6. Chemical biology - Wikipedia

    en.wikipedia.org/wiki/Chemical_biology

    Chemical biology is a scientific discipline between the fields of chemistry and biology. The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems. [ 1 ] Although often confused with biochemistry, which studies the ...

  7. Ligand (biochemistry) - Wikipedia

    en.wikipedia.org/wiki/Ligand_(biochemistry)

    Based on PDB: 1MBO . In biochemistry and pharmacology, a ligand is a substance that forms a complex with a biomolecule to serve a biological purpose. The etymology stems from Latin ligare, which means 'to bind'. In protein-ligand binding, the ligand is usually a molecule which produces a signal by binding to a site on a target protein.

  8. CHNOPS - Wikipedia

    en.wikipedia.org/wiki/CHNOPS

    CHNOPS. Graphic representation of carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur. CHNOPS and CHON are mnemonic acronyms for the most common elements in living organisms. "CHON" stands for c arbon, h ydrogen, o xygen, and n itrogen, which together make up more than 95 percent of the mass of biological systems. [1] ".

  9. Protein - Wikipedia

    en.wikipedia.org/wiki/Protein

    A protein is a polyamide. Secondary structure: regularly repeating local structures stabilized by hydrogen bonds. The most common examples are the α-helix, β-sheet and turns. Because secondary structures are local, many regions of different secondary structure can be present in the same protein molecule.
