  2. 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 ...

  3. AP Biology - Wikipedia

    en.wikipedia.org/wiki/AP_Biology

    Advanced Placement (AP) Biology (also known as AP Bio) is an Advanced Placement biology course and exam offered by the College Board in the United States. For the 2012–2013 school year, the College Board unveiled a new curriculum with a greater focus on "scientific practices".

  4. Gene regulatory network - Wikipedia

    en.wikipedia.org/wiki/Gene_regulatory_network

    Structure of a gene regulatory network Control process of a gene regulatory network. A gene (or genetic) regulatory network (GRN) is a collection of molecular regulators that interact with each other and with other substances in the cell to govern the gene expression levels of mRNA and proteins which, in turn, determine the function of the cell.

  5. Human iron metabolism - Wikipedia

    en.wikipedia.org/wiki/Human_iron_metabolism

    A relatively small amount (3–4 mg) circulates through the plasma, bound to transferrin. [9] Because of its toxicity, free soluble iron is kept in low concentration in the body. Iron deficiency first affects the storage of iron in the body, and depletion of these stores is thought to be relatively asymptomatic, although some vague and non ...

  6. Phosphodiester bond - Wikipedia

    en.wikipedia.org/wiki/Phosphodiester_bond

    Diagram of phosphodiester bonds (PO 3− 4) between three nucleotides. The 5' end has a 5' carbon attached to a phosphate, and the other end, the 3' end, has a 3' carbon attached to a hydroxyl group. The 5' end has a 5' carbon attached to a phosphate, and the other end, the 3' end, has a 3' carbon attached to a hydroxyl group.

    en.wikipedia.org/wiki/Molecular_Structure_of...

    The application of physics and chemistry to biological problems led to the development of molecular biology, which is particularly concerned with the flow and consequences of biological information from DNA to proteins. The discovery of the DNA double helix made clear that genes are functionally defined parts of DNA molecules, and that there ...

  8. Matrix-assisted laser desorption/ionization - Wikipedia

    en.wikipedia.org/wiki/Matrix-assisted_laser_de...

    The term matrix-assisted laser desorption ionization (MALDI) was coined in 1985 by Franz Hillenkamp, Michael Karas and their colleagues. [3] These researchers found that the amino acid alanine could be ionized more easily if it was mixed with the amino acid tryptophan and irradiated with a pulsed 266 nm laser.

  9. Lipogenesis - Wikipedia

    en.wikipedia.org/wiki/Lipogenesis

    In biochemistry, lipogenesis is the conversion of fatty acids and glycerol into fats, or a metabolic process through which acetyl-CoA is converted to triglyceride for storage in fat. [1]
