Me yasa rabon cistrans shine ɗaya daga cikin mahimman bayanai da za a yi bita a kan Takaddun Shaidar Binciken Lactone na Madara?

Wannan yana shiga cikin takamaiman nuances na sinadarai waɗanda ke bayyana inganci da halayen Milk Lactone.

Ga cikakken bayani:

1. Sinadarin Halitta: Dalilin da Ya Sa Isomerism Yake Da Muhimmanci a Lactones

Ga lactones kamar δ-Decalactone, laƙabin "cis" da "trans" ba ya nufin haɗin kai biyu (kamar yadda yake a cikin ƙwayoyin halitta kamar fatty acids) amma ga stereochemistry na dangi a cibiyoyin chiral guda biyu akan zoben. Tsarin zoben yana haifar da yanayi inda yanayin sararin samaniya na atoms na hydrogen da sarkar alkyl dangane da zoben ya bambanta.

· cis-Isomer: Kwayoyin hydrogen da ke kan ƙwayoyin carbon masu dacewa suna gefen zobe ɗaya. Wannan yana haifar da takamaiman siffa, mafi ƙuntatawa.

· trans-Isomer: Kwayoyin hydrogen suna a gefuna daban-daban na filin zobe. Wannan yana haifar da wani siffa daban, wanda ba shi da tsauri, kuma mai sauƙin tarawa.

Waɗannan ƙananan bambance-bambancen siffa suna haifar da manyan bambance-bambance a yadda kwayar halittar ke hulɗa da masu karɓar ƙamshi, don haka, bayanin ƙamshinsa.

2. Kashi a cikin Halitta da Na robaMadara Lactone

Tushe Matsakaicin Rabon Cis Isomer Matsakaicin Rabon Isomer Babban dalili

Na halitta (daga madara) > 99.5% (Aiki 100%) < 0.5% (Bincike ko babu) Hanyar halittar enzymatic a cikin saniya tana da tsari na musamman, tana samar da siffa (R) kawai da ke kaiwa ga cis-lactone.

Na roba ~70% – 95% ~5% – 30% Yawancin hanyoyin haɗa sinadarai (misali, daga petrochemicals ko ricinoleic acid) ba su da cikakken tsari na musamman, wanda ke haifar da cakuda isomers (racemate). Daidaitaccen rabo ya dogara ne akan takamaiman tsari da matakan tsarkakewa.

3. Tasirin Ji: Dalilin da yasa cis Isomer yake da Muhimmanci

Wannan rabon isomer ba wai kawai son sani ne na sinadarai ba; yana da tasiri kai tsaye da ƙarfi akan ingancin azanci:

· cis-δ-Decalactone: Wannan shine isomer mai ƙamshi mai matuƙar daraja, mai ƙarfi, mai kauri, mai kama da peach, da kuma mai kama da madara. Wannan shine mahaɗin tasirin hali gaMadara Lactone.

· trans-δ-Decalactone: Wannan isomer yana da rauni sosai, ba shi da wata siffa ta musamman, wani lokacin ma yana da ƙamshi mai "kore" ko "mai kitse". Ba ya ba da gudummawa sosai ga yanayin kirim ɗin da ake so kuma a zahiri yana iya narke ko ɓata tsarkin ƙamshin.

4. Abubuwan da ke haifar da Masana'antar Ɗanɗano da Ƙamshi

Kason cis zuwa trans isomer alama ce mai mahimmanci ta inganci da farashi:

1. Lactones na Halitta (daga Dairy): Saboda suna da kashi 100% na cis, suna da ƙamshi mafi inganci, ƙarfi, da kuma abin so. Haka kuma su ne mafi tsada saboda tsadar tsarin cirewa daga tushen kiwo.

2. Lactones na Hana ...

3. Lactones na roba na yau da kullun: Ƙarancin abun ciki na cis (misali, 70-85%) yana nuna cewa samfurin ba shi da wari mai kyau. Zai yi ƙamshi mai rauni, kuma ba shi da asali kuma ana amfani da shi a aikace inda farashi shine babban abin da ke haifar da ƙamshi mai inganci ba shi da mahimmanci.

Kammalawa

A taƙaice, rabon ba lamba ce mai ƙayyadadden lamba ba, amma babbar alama ce ta asali da inganci:

A yanayi, rabon ya karkace sosai zuwa >99.5% cis-isomer.

· A cikin hadawa, rabon ya bambanta, amma babban abun ciki na cis-isomer yana da alaƙa kai tsaye da ƙamshi mai kyau, na halitta, kuma mai ƙarfi.

Saboda haka, lokacin da aka kimanta samfurinMadara Lactone, rabon cis/trans yana ɗaya daga cikin mahimman bayanai da za a yi bita a kansu akan Takaddun Shaidar Bincike (COA).
