  2. Sterol - Wikipedia

    en.wikipedia.org/wiki/Sterol

    Molar mass. 248.410 g·mol −1. Except where otherwise noted, data are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Infobox references. Sterol is an organic compound [1] with formula C. 17H. 28O, whose molecule is derived from that of gonane by replacement of a hydrogen atom on C3 position by a hydroxyl group.

  3. Ergosterol - Wikipedia

    en.wikipedia.org/wiki/Ergosterol

    Ergosterol (ergosta-5,7,22-trien-3β-ol) is a mycosterol found in cell membranes of fungi and protozoa, serving many of the same functions that cholesterol serves in animal cells. Because many fungi and protozoa cannot survive without ergosterol, the enzymes that synthesize it have become important targets for drug discovery.

  4. Methylisothiazolinone - Wikipedia

    en.wikipedia.org/wiki/Methylisothiazolinone

    Methylisothiazolinone (/ ˌmɛθəlˌaɪsoʊˌθaɪ.əˈzoʊlɪnoʊn /), MIT, or MI, is the organic compound with the formula S (CH) 2 C (O)NCH 3. It is a white solid. Isothiazolinones, a class of heterocycles, are used as biocides in numerous personal care products and other industrial applications. MIT and related compounds have attracted ...

  5. Beaker (laboratory equipment) - Wikipedia

    en.wikipedia.org/wiki/Beaker_(laboratory_equipment)

    In laboratory equipment, a beaker is generally a cylindrical container with a flat bottom. [1] Most also have a small spout (or "beak") to aid pouring, as shown in the picture. Beakers are available in a wide range of sizes, from one milliliter up to several liters. A beaker is distinguished from a flask by having straight rather than sloping ...

  6. Aquaporin - Wikipedia

    en.wikipedia.org/wiki/Aquaporin

    Aquaporin. Aquaporins, also called water channels, are channel proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. [1] The cell membranes of a variety of different bacteria, fungi, animal and plant cells contain aquaporins through ...

  7. Total dissolved solids - Wikipedia

    en.wikipedia.org/wiki/Total_dissolved_solids

    Bottled mineral water usually contains higher TDS levels than tap water. Total dissolved solids (TDS) is a measure of the dissolved combined content of all inorganic and organic substances present in a liquid in molecular, ionized, or micro-granular (colloidal sol) suspended form. TDS are often measured in parts per million (ppm).

  8. Functional group - Wikipedia

    en.wikipedia.org/wiki/Functional_group

    In organic chemistry, a functional group is a substituent or moiety in a molecule that causes the molecule's characteristic chemical reactions. The same functional group will undergo the same or similar chemical reactions regardless of the rest of the molecule's composition. [1][2] This enables systematic prediction of chemical reactions and ...

  9. Micelle - Wikipedia

    en.wikipedia.org/wiki/Micelle

    A micelle (/ maɪˈsɛl /) or micella (/ maɪˈsɛlə /) (pl. micelles or micellae, respectively) is an aggregate (or supramolecular assembly) of surfactant amphipathic lipid molecules dispersed in a liquid, forming a colloidal suspension (also known as associated colloidal system). [4] A typical micelle in water forms an aggregate with the ...
