Ụlọ ọrụ ALKYL MONOGLUCOSIDES

Alkyl monoglucosides nwere otu D-glucose unit.Ihe owuwu mgbanaka ahụ bụ nke otu D-glucose.Ma mgbanaka ndị otu ise na isii nke gụnyere otu oxygen atom ka heteroatom na-ejikọta na furan ma ọ bụ usoro pyran.Ya mere, a na-akpọ Alkyl D-glucosides nwere mgbanaka mmadụ ise alkyl d-glucofuranosides, na ndị nwere mgbanaka isii, alkyl D-glucopyranosides.

Ngalaba D-glucose niile na-egosi ọrụ acetal nke carbon carbon bụ naanị nke a ga-ejikọta na atọm oxygen abụọ.A na-akpọ nke a anomeric carbon atom ma ọ bụ etiti anomeric.Ihe a na-akpọ njikọ glycosidic na ihe fọdụrụ na alkyl, yana njikọ ya na ikuku oxygen nke mgbanaka saccharide, sitere na atom carbon atom.Maka ntụzịaka na yinye carbon, a na-agụ carbon carbon nke D-glucose nkeji na-aga n'ihu (C-1 ruo C-6) malite na carbon carbon anomeric.A na-agụ mkpụrụ ikuku oxygen dị ka ọnọdụ ha dị na yinye (O-1 ruo O-6).Atọm carbon anomeric na-anọchi anya asymmetrically ma nwee ike were nhazi abụọ dị iche iche.A na-akpọ stereoisomer ndị a na-esi na ya pụta anomers ma bụrụ ndị pụrụ iche site na prefix α ma ọ bụ β.Dị ka nkwekọrịta nomenclature anomers na-egosi na otu n'ime nhazi abụọ nwere ike ime nke njikọ glycosidic na-atụ aka nri na Fischer projection formulas nke glucosides.Kpọmkwem ihe dị iche bụ eziokwu nke anomers.

Na nomenclature nke carbohydrate kemịkalụ, aha nke alkyl monoglucoside bụ nke mejupụtara aha a: Nhazi nke alkyl residue, nhọpụta nke anomeric nhazi, syllable "D-gluc," nhọpụta nke cyclic ụdị, na mgbakwunye na nke njedebe " oside."Ebe mmeghachi omume kemịkalụ na saccharides na-emekarị na anomeric carbon atom ma ọ bụ ikuku oxygen nke ndị isi ma ọ bụ nke abụọ hydroxyl, nhazi nke carbon carbon asymmetrical anaghị agbanwe agbanwe, ma e wezụga na etiti anomeric.N'akụkụ a, nomenclature maka alkyl glucosides dị nnọọ irè, ebe ọ bụ na syllable "D-gluc" nke nne na nna saccharide D-glucose na-edobe n'ọnọdụ nke ọtụtụ ụdị mmeghachi omume na-emekarị na mgbanwe kemịkalụ nwere ike ịkọwa site na suffixes.

Ọ bụ ezie na usoro nke saccharide nomenclature nwere ike ịmepụta nke ọma dị ka usoro amụma Fischer si dị, a na-ahọrọkarị usoro Haworth nwere ihe nnọchianya cyclic nke eriri carbon dị ka usoro nhazi maka saccharides.Atụmatụ Haworth na-enye echiche dị n'ọgbara ka mma maka nhazi molikula nke nkeji Glucose ma bụrụkwa nke a masịrị ya na akwụkwọ akụkọ a.Na usoro Haworth, a naghị ewepụtakarị atom hydrogen jikọtara na mgbanaka saccharide.
