  2. Aliphatic compound - Wikipedia

    en.wikipedia.org/wiki/Aliphatic_compound

    Most aliphatic compounds are flammable, allowing the use of hydrocarbons as fuel, such as methane in natural gas for stoves or heating; butane in torches and lighters; various aliphatic (as well as aromatic) hydrocarbons in liquid transportation fuels like petrol/gasoline, diesel, and jet fuel; and other uses such as ethyne (acetylene) in welding.

  3. Secondary metabolite - Wikipedia

    en.wikipedia.org/wiki/Secondary_metabolite

    Plants are capable of producing and synthesizing diverse groups of organic compounds and are divided into two major groups: primary and secondary metabolites. [9] Secondary metabolites are metabolic intermediates or products which are not essential to growth and life of the producing plants but rather required for interaction of plants with their environment and produced in response to stress.

  4. Aromatic amino acid - Wikipedia

    en.wikipedia.org/wiki/Aromatic_amino_acid

    Aromatic amino acids, excepting histidine, absorb ultraviolet light above and beyond 250 nm and will fluoresce under these conditions. This characteristic is used in quantitative analysis, notably in determining the concentrations of these amino acids in solution. [1] [2] Most proteins absorb at 280 nm due to the presence of tyrosine and ...

  5. Naturally occurring phenols - Wikipedia

    en.wikipedia.org/wiki/Naturally_occurring_phenols

    The hardening of the protein component of insect cuticle has been shown to be due to the tanning action of an agent produced by oxidation of a phenolic substance forming sclerotin. [ citation needed ] In the analogous hardening of the cockroach ootheca , the phenolic substance concerned is 3:4-dihydroxybenzoic acid ( protocatechuic acid ).

  6. Essential amino acids in plant food - Wikipedia

    en.wikipedia.org/wiki/Essential_amino_acids_in...

    EAAs are provided in both animal and plant-based food. The EAAs in plants vary greatly due to the vast variation in the plant world and, in general, plants have much lower content of proteins than animal food. [2] [3] Some plant-based foods contain few or no EAAs, e.g. some sprouts, mango, pineapple, lime and melon. On the other hand, nuts ...

  7. Arabinogalactan protein - Wikipedia

    en.wikipedia.org/wiki/Arabinogalactan_protein

    Arabinogalactan-proteins (AGPs) are highly glycosylated proteins (glycoproteins) found in the cell walls of plants. Each one consists of a protein with sugar molecules attached (which can account for more than 90% of the total mass). They are members of the wider class of hydroxyproline (Hyp)-rich cell wall glycoproteins, a large and diverse ...

  8. Hydrocarbon - Wikipedia

    en.wikipedia.org/wiki/Hydrocarbon

    Aromatic hydrocarbons, also known as arenes, which are hydrocarbons that have at least one aromatic ring. 10% of total nonmethane organic carbon emission are aromatic hydrocarbons from the exhaust of gasoline-powered vehicles. [4] The term 'aliphatic' refers to non-aromatic hydrocarbons.

  9. Asparagine - Wikipedia

    en.wikipedia.org/wiki/Asparagine

    Asparagine (symbol Asn or N [2]) is an α-amino acid that is used in the biosynthesis of proteins.It contains an α-amino group (which is in the protonated −NH + 3 form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO − form under biological conditions), and a side chain carboxamide, classifying it as a polar (at physiological pH), aliphatic ...
