The crystal lattice of solid americium and its compounds contains intrinsic defects, which are induced by self-irradiation with alpha particles and accumulate with time ; this results in a drift of some material properties.

9 of the 20 standard amino acids are called " essential " amino acids for humans because they cannot be created from other compounds by the human body, and so must be taken in as food.

Of the 22 standard amino acids, 9 are called essential amino acids because the human body cannot synthesize them from other compounds at the level needed for normal growth, so they must be obtained from food.

Some non-benzene-based compounds called heteroarenes, which follow Hückel's rule, are also aromatic compounds.

In organic chemistry, compounds composed of carbon and hydrogen are divided into two classes: aromatic compounds, which contain benzene or similar rings of atoms, and aliphatic compounds (; G. aleiphar, fat, oil ), which do not contain those rings.

They can be divided into three major classes: aromatic nitro musks, polycyclic musk compounds, and macrocyclic musk compounds.

These phytochemicals are divided into ( 1 ) primary metabolites such as sugars and fats, which are found in all plants ; and ( 2 ) secondary metabolites -- compounds which are found in a smaller range of plants, serving a more specific function.

Uzbekistan is divided into 12 provinces ( viloyatlar, singularviloyat, viloyati in compound, e. g. Toshkent viloyati, Samarqand viloyati ), 1 autonomous republic ( respublika, respublikasi in compound, e. g. Qaraqalpaqstan Avtonom Respublikasi, Karakalpakstan Autonomous Republic ), and 1 independent city ( shahar or shahri in compounds, e. g. Toshkent shahri, Tashkent city ).

Compounds used as medicines are most often organic compounds, which are often divided into the broad classes of small organic molecules ( e. g., atorvastatin, fluticasone, clopidogrel ) and " biologics " ( infliximab, erythropoietin, insulin glargine ), the latter of which are most often medicinal preparations of proteins ( natural and recombinant antibodies, hormones, etc .).

Marlag, the Royal Navy camp, was divided into two compounds ; " O " housed officers and their orderlies, while " M " held NCOs and ratings.

This also divided into two separate compounds for officers and men.

The camp was divided into five compounds ( A-E ) separated by barbed wire fences, with the POWs housed in 40 wooden barrack huts, each containing 200 men.

With the discovery of organisms that oxidized inorganic compounds such as hydrogen sulfide and ammonium as energy sources, autotrophs could be divided into two groups: photoautotrophs and chemoautotrophs.

The use of biocatalysis to obtain enantiopure compounds can be divided into two different methods:

As late as the 1840s, and despite Friedrich Wöhler's synthesis of urea in 1828, some chemists still believed in the doctrine of vitalism, according to which a special life-force was necessary to create organic compounds.

Organic compounds are named according to the organic nomenclature system.

Inorganic compounds are named according to the inorganic nomenclature system.

Different compounds in the sample mixture travel different distances according to how strongly they interact with the stationary phase as compared to the mobile phase.

While Proust believed that chemical compounds are composed of a fixed ratio of their constituent elements irrespective of the methods of production, Berthollet believed that this ratio can change according to the ratio of the reactants initially taken.

Organic compounds are classified according to functional groups, alcohols, carboxylic acids, amines, etc.

With better calculation methods and studies of the chemical properties of rutherfordium compounds it could be shown that rutherfordium behaves according to the rest of the group 4 elements.

Other compounds that are sometimes referred to as zwitterions, mistakenly according to the definition above, include nitrones and " dipolar compounds ", such as a 1, 2-dipole and a 1, 3-dipole.

These compounds have been classified into three main types according to the nature of their bonding:

Substances found, according to the reports, are naphthol, naphthalene, Sevin, tarry residues, alpha naphthol, mercury, organochlorines, chromium, copper, nickel, lead, hexachlorethane, Hexachlorobutadiene, pesticide HCH ( BHC ), volatile organic compounds and halo-organics.

Throughout the history of fabric production natural dyes have been used to apply a form of colour, with dyes from plants, including indigo from Woad, having dozens of compounds whose proportions may vary according to soil type and climate ; therefore giving rise to variations in shade.

Plants and algae produce the most preservable compounds, which are listed according to their preservation potential by Tegellaar ( see reference ).

These compounds are responsible for what Metchnikoff called intestinal auto-intoxication, which, according to him, was the cause of the physical changes associated with old age.

At this period the compounds employed in medicine were often heterogeneous mixtures, some of which contained from 20 to 70, or more, ingredients, while a large number of simples were used in consequence of the same substance being supposed to possess different qualities according to the source from which it was derived.

Catechol, resorcinol, pyrogallol, and phloroglucinol, all di-and trihydroxylated benzene ( C6 ) derivatives, are still defined as “ phenols ” according to the IUPAC official nomenclature rules of chemical compounds.

These chemists demonstrated that the chemical compounds are not composed of random clusters of atoms and functional groups, but have structures with a definite order formed according the valency of the composing atoms.

Ion exchange chromatography separates compounds according to the nature and degree of their ionic charge.

Recent epidemiological findings support the process of mitohormesis in humans, and even suggest that the intake of exogenous antioxidants may increase disease prevalence in humans ( according to the theory, because they prevent the stimulation of the organism's natural response to the oxidant compounds which not only neutralizes them but provides other benefits as well ).

The aims of nutrigenomics also includes being able to demonstrate the effect of bioactive food compounds on health and the effect of health foods on health, which should lead to the development of functional foods that will keep people healthy according to their individual needs.
