  2. Diaminopimelic acid - Wikipedia

    en.wikipedia.org/wiki/Diaminopimelic_acid

    Diaminopimelic acid (DAP) is an amino acid, representing an epsilon-carboxy derivative of lysine. meso -α,ε-Diaminopimelic acid is the last intermediate in the biosynthesis of lysine and undergoes decarboxylation by diaminopimelate decarboxylase to give the final product.

  3. Diammonium phosphate - Wikipedia

    en.wikipedia.org/wiki/Diammonium_phosphate

    Diammonium phosphate (DAP; IUPAC name diammonium hydrogen phosphate; chemical formula (NH 4) 2 (HPO 4)) is one of a series of water-soluble ammonium phosphate salts that can be produced when ammonia reacts with phosphoric acid. Solid diammonium phosphate shows a dissociation pressure of ammonia as given by the following expression and equation: [2]

  4. Canalisation (genetics) - Wikipedia

    en.wikipedia.org/wiki/Canalisation_(genetics)

    Waddington used the concept of canalisation to explain his experiments on genetic assimilation. [3] In these experiments, he exposed Drosophila pupae to heat shock. This environmental disturbance caused some flies to develop a crossveinless phenotype.

    [2] in other words, when some factor is sufficient to cause an effect, the presence of the cause guarantees the occurrence of the effect. [3] However, a different cause z may also cause y, meaning that y may occur without x occurring. [2] [3] For a concrete example, consider the conditional statement "if an object is a square, then it has four ...

    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".

  7. Coenzyme A - Wikipedia

    en.wikipedia.org/wiki/Coenzyme_A

    Coenzyme A (CoA, SHCoA, CoASH) is a coenzyme, notable for its role in the synthesis and oxidation of fatty acids, and the oxidation of pyruvate in the citric acid cycle.All genomes sequenced to date encode enzymes that use coenzyme A as a substrate, and around 4% of cellular enzymes use it (or a thioester) as a substrate.

  8. Cotransporter - Wikipedia

    en.wikipedia.org/wiki/Cotransporter

    [2] Cotransporters can be classified as antiporters and symporters. Both use electric potential and/or chemical gradients to move protons and ions against their concentration gradient. In plants the proton is considered a secondary substance, and high proton concentration in the apoplast powers the inward movement of certain ions by symporters.

  9. SMAD (protein) - Wikipedia

    en.wikipedia.org/wiki/SMAD_(protein)

    [4] Smad4 is the only known human Co-Smad, and has the role of partnering with R-Smads to recruit co-regulators to the complex. [5] Finally, Smad6 and Smad7 are I-Smads that work to suppress the activity of R-Smads. [6] [7] While Smad7 is a general TGF-B signal inhibitor, Smad6 associates more specifically with BMP signaling. R/Co-Smads are ...
