The C-terminal amino acid of peptides can be reduced with lithium borohydride to the corresponding [alpha]-amino alcohol. If the peptide chain is then completely hydrolyzed, the hydrolyzate will contain one molecule of an [alpha]-amino alcohol corresponding to the original C-terminal amino acid. This can be easily identified by chromatographic methods; all the other residues will be found as free amino acids. Another important procedure is hydrazinolysis, which cleaves all the peptide bonds by converting all except the C-terminal amino acid residues into hydrazides. The C-terminal residue appears as a free amino acid, which can be readily identified chromatographically. 1, record 3, English, - free%20amino%20acid

Pour identifier l'aminoacide N-terminal d'un peptide, on dispose de trois méthodes : l'une d'elles utilise la réaction de Sanger. Les fonctions non protonisées [alpha]-aminées des amino-acides et peptides réagissent avec le 2,4-dinitrofluorobenzène pour former des dérivés jaunes, les 2,4-DNP-peptides. Lorsque ces 2,4-DNP-peptides sont soumis à une hydrolyse acide, on obtient l'hydrolysat contenant tous les résidus de la chaîne peptidique sous forme d'amino-acides libres, à l'exception de l'aminoacide N-terminal qui sera présent sous forme d'un 2,4-dinitrophényl-dérivé. 2, record 3, French, - acide%20amin%C3%A9%20libre

La structure des acides aminés conditionne le repliement des protéines. Dans un acide aminé isolé, quatre groupes chimiques sont liés à un atome de carbone central, le carbone alpha; ces groupes sont un groupe amine NH2, un groupe carboxyle (COOH), un atome d'hydrogène et une chaîne latérale (notée R). Les 20 acides aminés ne diffèrent que par leur chaîne latérale. Dans une protéine, le groupe aminé d'un acide aminé est lié au groupe carboxyle de l'acide aminé suivant (avec élimination d'une molécule d'eau), formant ainsi une liaison peptidique. La mise en commun des électrons (leur délocalisation) entre les atomes d'azote, de carbone et d'oxygène empêche les protéines de tourner librement autour des liaisons peptidiques; chaque unité peptidique définit un plan rigide et les protéines ne peuvent se replier que par rotation autour des liaisons avec le carbone alpha. 4, record 4, French, - carboxyle

Bile acids are steroids, having a hydroxyl group, and a five-carbon-atom side chain terminating in a carboxyl group. Cholic acid is the most abundant bile acid in human bile. Others are deoxycholic and lithocholic acids. The bile acids do not occur free in bile but are linked to the amino acids, glycine and taurine. These conjugated acids are water-soluble; their salts are powerful detergents and as such, aid in the absorption of fats from the intestine. 4, record 12, English, - bile%20acid

("Unusual" means a base other than A, G, C, or U.) Many of the unusual bases differ from normal bases by the presence of one or more methyl(-CH3) groups. Most, if not all, of the methyl groups are enzymatically added after the nucleotides are linked together by 3’-5’ phosphodiester linkages. Very probably, the other unusual bases also arise by the enzymatic modification of a preexisting polynucleotide. The function of the unusual bases is not yet clear. They are not limited to alanine tRNA but occur in varying proportions in all tRNA molecules. Our only hint of their role is the fact that several unusual bases cannot form conventional base pairs. Some of the unusual bases may thus have the function of disruption double-helical hairpin regions, thereby exposing free keto and amino groups which can then form secondary bonds. Depending upon the specific bases, the free groups may form secondary bonds to template RNA, to a ribosome, or to the enzyme needed to attach a specific amino acid to its specific tRNA molecule. [Examples of those rare nucleotides are : Inosine, 1-methylinosine, N2-dimethylguanosine, 1-methylguanosine, Ribothymidine, Dihydrouridine and Pseudouridine]. 1, record 15, English, - unusual%20base

Les deux classes de bases trouvées dans tous les mononucléotides sont dérivées de corps aromatiques hétérocycliques appelés purine et pyrimidine. La purine dérive elle-même de la pyrimidine par la fusion d'un cycle pyrimidine et imidazole. Les trois bases pyrimidiques les plus communes sont : l'uracile, la thymine et la cytosine, désignées couramment par U, T et C respectivement. Les bases puriques intervenant le plus souvent comme composantes des mononucléotides sont l'adénine et la guanine, respectivement désignées par A et G. Il existe [aussi] de nombreuses bases rares, telles que la 5-méthylcytosine, ou la 5-hydroxyméthyl-cytosine, [l'ionosine, la pseudouridine, etc...] Le rôle de ces bases rares n'est pas clair pour l'instant. Elles (...) existent en proportions variables dans toutes les molécules de tARN. Seul indice connu sur leur rôle possible, ces bases rares ne peuvent pas s'apparier de la manière habituelle. Certaines de ces bases rares pourraient donc avoir pour fonction de provoquer l'ouverture de quelques régions en épingle à cheveux de la double hélice, exposant ainsi des groupements cétones et aminés libres susceptibles de former des liaisons secondaires. Selon la nature des bases exposées, ces groupements libres pourraient former des liaisons secondaires avec la matrice d'ARN, avec le ribosome ou avec l'enzyme qui attache l'acide aminé à son tARN spécifique. 1, record 15, French, - base%20rare
