Kervran Preuves en Biologie de Transmutations à Faible Énergie, Paris 1975, Maloine, ISBN 2-224-00178-9 .</ ref > Some strange cases of industrial accidents ( 1955 ) showing CO poisoning when no CO was inhaled led Kervran to postulate the dissociation of a nitrogen molecule into carbon monoxide through the displacement of a proton at low energy.

Some phagocytes kill the ingested pathogen with oxidants and nitric oxide.

Some pathogenic organisms are typically ingested by other routes.

Some people have intentionally ingested large amounts of oil of wintergreen.

Some kind of valve or sphincter is likely present to prevent reflux of ingested blood.

Some tapeworms have fleas as intermediate hosts: the worm egg must be consumed by a flea to hatch, then the infected flea must be ingested ( usually by the dog while grooming itself, but occasionally by a human through various means ) for the adult worm to establish itself in the intestines.

Some nonstandard amino acids are not found in proteins.

Some combinations of amino acids will tend to curl up in a coil called an α-helix or into a sheet called a β-sheet ; some α-helixes can be seen in the hemoglobin schematic above.

Some web-servers and bioinformatics prediction methods have been used for predicting the classification of GPCRs according to their amino acid sequence alone, by means of the pseudo amino acid composition approach.

Some of the amino acids are convertible ( with the expenditure of energy ) to glucose and can be used for energy production, just as ordinary glucose, in a process known as gluconeogenesis.

Some of them can detach the terminal amino acids from the protein chain ( exopeptidases, such as aminopeptidases, carboxypeptidase A ); the others attack internal peptide bonds of a protein ( endopeptidases, such as trypsin, chymotrypsin, pepsin, papain, elastase ).

Some fingerprint reagents are specific, for example ninhydrin or diazafluorenone reacting with amino acids.

Some of the amino acids are convertible ( with the expenditure of energy ) to glucose and can be used for energy production just as ordinary glucose.

Some ligands include the sulfate anion, the collagen's carboxyl groups, amine groups from the side chains of the amino acids, as well as " masking agents.

Some of the amino acid substrates become N-methylated by S-adenosyl methionine.

Some researchers have speculated that the two amino acid differences between chimps and humans led to the evolution of language in humans.

< li > Some amino acids are catabolized into both glucogenic and ketogenic products.

Some categories of essential nutrients include vitamins, dietary minerals, essential fatty acids, and essential amino acids.

Some amino acids, such as lysine, contain a primary amine on their side chains.

Some patients may need to have supplemental amino acids ( arginine, citrulline, valine, leucine, isoleucine ).

Some CADASIL patients have used L-Arginine, a naturally occurring amino acid, to ease symptoms such as headache.

Some examples of successful metabolic engineering are the following: ( i ) Identification of constraints to lysine production in corynebacterium glutamicum and insertion of new genes to relieve these constraints to improve production ( ii ) Engineering of a new fatty acid biosynthesis pathway, called reversed beta oxidation pathway, that is more efficient than the native pathway in producing fatty acids and alcohols which can potentially be catalytically converted to chemicals and fuels ( iii ) Improved production of DAHP ( 3-deoxy-D-arabino-heptulosonate 7-phosphate ), an aromatic metabolite produced by E. coli that is an intermediate in the production of aromatic amino acids.

Some believe it is unlikely that primordial Earth had such a distribution of amino acids available on its surface.

Some of these drawbacks include the installation and preservation of a reactive C-terminal thioester, the requirement of an N-terminal cysteine residue ( which is the second least common amino acid in proteins, and the requirement for a sterically unincumbering C-terminal residue.

Some combinations of proteinogenic amino acid side chains meet the criteria, as do ketones and aldehydes ( which can tag proteins and some metabolites ).

Some of these functional groups include hydrocarbon chains of variable length ( for reversed phase SPE ), quaternary ammonium or amino groups ( for anion exchange ), and sulfonic acid or carboxyl groups ( for cation exchange ).

Some acids like tariric acid contains an alkyne group.

Some fatty acids are essential nutrients, meaning that they can't be produced in the body from other compounds and need to be consumed in small amounts.

Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body.

Some species can metabolize pentose sugars like ribose, alcohols, and organic acids.

Some types of Monounsaturated fatty acids, saturated, and trans fats promote insulin resistance.

Some types of polyunsaturated fatty acids ( omega-3 ) can moderate the progression of insulin resistance into type 2 diabetes.

Some resins also contain a high proportion of resin acids.

Some types of soluble fibers bind to bile acids in the small intestine, making them less likely to enter the body ; this in turn lowers cholesterol levels in the blood.

Some non-absorbed carbohydrates, e. g. pectin, gum arabic, oligosaccharides and resistant starch, are fermented to short-chain fatty acids ( chiefly acetic, propionic and n-butyric ), and carbon dioxide, hydrogen and methane.

Some Silphidae beetles secrete a chemical from a rectal gland that consists of aliphatic acids and terpene alcohols.

Some fatty acids, but not all, are essential in the diet: they cannot be synthesized in the body.

Some of the food sources of ω-3 and ω-6 fatty acids are fish and shellfish, flaxseed ( linseed ), hemp oil, soya oil, canola ( rapeseed ) oil, chia seeds, pumpkin seeds, sunflower seeds, leafy vegetables, and walnuts.

:* Some concentrated weak acids, for example formic acid and acetic acid

Some brands of peanut butter may contain a small amount of added partially hydrogenated vegetable oils, which are high in trans fatty acids, thought to be a cause of atherosclerosis, coronary heart disease, and stroke ; these oils are added to prevent the peanut oil from separating.

Some are alcohols, hydrocarbons, ethers, epoxides, ketones, acids, etc.

Some of these are believed to affect the shape of nucleic acids ( see for example RNA self-splicing ), but this is only sometimes the case.
