Hence mammals cannot synthesize linoleate or linolenate (which have double bonds at the C-12 (= Δ 12), or the C-12 and C-15 (= Δ 12 and Δ 15) positions, respectively, as well as at the Δ 9 position), nor the polyunsaturated, 20-carbon arachidonic acid that is derived from linoleate.

For a protein containing n amino acids, the number of high-energy phosphate bonds required to translate it is 4n-1. [9] The rate of translation varies; it is significantly higher in prokaryotic cells (up to 17–21 amino acid residues per second) than in eukaryotic cells (up to 6–9 amino acid residues per second).

Venenivibrio stagnispumantis gains energy by oxidizing hydrogen gas.. In biochemistry, chemosynthesis is the biological conversion of one or more carbon-containing molecules (usually carbon dioxide or methane) and nutrients into organic matter using the oxidation of inorganic compounds (e.g., hydrogen gas, hydrogen sulfide) or ferrous ions as a source of energy, rather than sunlight, as in ...
By spring 1934 Chapter 12 was in its final form. [49] His lectures in autumn of that year bore the title 'the general theory of employment'. [50] In these lectures Keynes presented the marginal efficiency of capital in much the same form as it took in Chapter 11, his 'basic chapter' as Kahn called it. [51]
Many multivitamin formulas contain vitamin C, B 1, B 2, B 3, B 5, B 6, B 7, B 9, B 12, A, E, D 2 (or D 3), K, potassium, iodine, selenium, borate, zinc, calcium, magnesium, manganese, molybdenum, beta carotene, and/or iron. Multivitamins are typically available in a variety of formulas based on age and sex, or (as in prenatal vitamins) based on ...
This article needs attention from an expert in biochemistry.The specific problem is: someone with a solid grasp of the full scope of this subject and of its secondary and advanced teaching literatures needs to address A, the clear structural issues of the article (e.g., general absence of catabolic biosynthetic pathways, insertion of macromolecule anabolic paths before all building blocks ...
