Praktikumsbericht / -arbeit aus dem Jahr 2015 im Fachbereich Chemie - Lebensmittelchemie, be aware: 2, , Sprache: Deutsch, summary: Der vorliegende Bericht zum Lebensmittelchemischen Grundpraktikum A widmet sich dem Themenkreis „Wasser und Fette“.

Wasser ist das am häufigsten vorkommende Molekül. Es stellt die Grundlage des Lebens dar. Der menschliche Körper besteht aus 60 bis 70 % aus Wasser. Es übernimmt dabei im Körper regulatorische Aufgaben wie die Steuerung des Wärmehaushalts. Daneben fungiert es als Lösungs- und Transportmittel für polare und ionisierte Verbindungen, ist Strukturbestandteil von Makromolekülen und dient als Substrat enzymatischer Reaktionen.
Wasser besteht aus zwei Wasserstoffatomen und einem Sauerstoffatom und bildet somit die Summenformel H2O. Aufgrund der dipolaren Struktur, bei der das Sauerstoffatom negativ und die Wasserstoffatome positiv geladen sind, bildet Wasser Cluster aus, die durch Wasserstoffbrückenbindungen stabilisiert werden. Aus dieser Eigenschaft resultieren die Anomalien des Wassers. Durch die Wechselwirkung der einzelnen Wassermoleküle durch Wasserstoffbrückenbindungen ergibt sich der hohe Siedepunkt, der enorm von dem Siedepunkt der Hydride der Hauptgruppe abweicht (Bsp. Schwefelwasserstoff: -61 °C).

Aus dem Inhalt:
- Bestimmung der Trockenmasse in Fleisch und Fleischerzeugnisse;
- Wasserbestimmung in Lebensmitteln nach KARL-FISCHER;
- Extraktion nach Säure-Aufschluss (Methode nach WEIBULL-STOLDT);
- Extraktion nach ammoniakalischen Aufschluss (Methode nach RÖSE-GOTTLIEB);
- Chemikalien und Entsorgung

In this thesis, the writer introduces concepts used to build quite a few forms of N-heterocycles, in line with the chemistry of zirconacycles and 2,6-diazasemibullvalenes. within the first half, the writer provides the improvement of multi-component cyclization of a zirconacyclobutene-silacyclobutene fused compound, nitriles and unsaturated compounds. those reactions offer synthetically helpful technique for numerous N-heterocycles similar to 3-acyl pyrrole, pyrrolo[3,2-d]pyridazine and dihydropyrroloazepine, that are all tough to synthesize by way of different capacity. The isolation and characterization of the foremost three-fused-ring Zr/Si-containing intermediates also are defined intimately. those effects express that the zirconacyclobutene-silacyclobutene fused compound behaves as a “chemical transformer” upon remedy with numerous substrates through the “coordination-induced skeleton rearrangement” mechanism. within the moment half, the writer demonstrates the synthesis and isolation of a chain of 2,6-diazasemibullvalenes (NSBVs) from the response of 1,4-dilithio-1,3-dienes and nitriles, highlighting the numerous growth made for the 1st time during this paintings: (1) choice of X-ray crystal constitution of a substituted 2,6-diazasemibullvalene; (2) dimension of the activation barrier of its fast intramolecular aza-Cope rearrangement in answer; (3) exploration of a number of response varieties of NSBV with diversified ring-expansion items and “bowl-shape” or “cage-shape” N-containing polycyclic skeletons; (4) demonstration of the localized constitution because the fundamental shape and the homoaromatic delocalized constitution as a minor part within the equilibrium utilizing theoretical research. in line with well-founded effects, this paintings sheds new mild in this arguable topic.

By F. Serratosa,J. Xicart

ISBN-10: 0444883452

ISBN-13: 9780444883452

the 1st version of this booklet used to be welcomed with nice enthusiasm via lecturers and scholars. It hence appeared opportune to post a moment, revised, up to date and prolonged variation. regrettably, Professor Fèlix Serratosa died prior to he might whole this task.

Some new fabric has been further, the extra major alterations being:

1) The e-book has been restructured into well-differentiated sections: half A, facing conventional natural synthesis, and half B, committed completely to computer-assisted natural synthesis and in accordance with the previous bankruptcy eleven and Appendices 2, three and four of the 1st version. As made up our minds upfront, half B used to be to be the only accountability of Dr. Josep Xicart, who ready the 1st models of the CHAOS (Computerisation and Heuristics utilized to natural Synthesis) software below the course of Professor Serratosa.

2) In bankruptcy 1, emphasis is put on new pursuits and pursuits, in addition to at the function that natural synthesis may still play sooner or later in new parts of supramolecular chemistry and bioorganic chemistry.

3) A extra prolonged dialogue on man made equipment and methods in keeping with radical carbon-carbon bond-forming reactions has been integrated (Chapter 7).

4) a few new examples to demonstrate the heuristic rules were integrated (Chapter 4).

5) The bankruptcy on alicyclic stereoselection has been cut up into chapters (9 and 10). bankruptcy 10, that is solely dedicated to Sharpless's uneven epoxidation and dihyroxylation, has been written de novo. the newest advances in catalytic stereoselective aldol are integrated in bankruptcy 9.

6) In bankruptcy eleven, that is new, the purpose is to to start with, current a breathtaking view of an important equipment for instruction of optically natural compounds in commercial scale (chirotechnology) and secondly, to provide a short perception into the recent organic artificial methodologies, equivalent to using enzymes and catalytic monoclonal antibodies or abzymes, that are turning into a growing number of very important and regularly occurring to the bogus natural chemist.

7) The bankruptcy facing examples of retrosynthetic research and the corresponding overall synthesis has been enlarged and comprises new syntheses of average items (Chapter 13).

8) the previous bankruptcy eleven and Appendices 2, three and four dedicated to laptop assisted natural synthesis were rewritten and represent now half B of the ebook. the subsequent adjustments were brought: i) CHAOS model 3.0 for Macintosh and model 1.0 for computer Windows® replacement CHAOS model 2.0 for IBM computer and compatibles, ii) The corresponding guideline Manuals and Disconnection Tables of those new types are incorporated, iii) three½ inch diskettes with the hot models of CHAOS and CHAOSDBASE change the diskette of model 2.0, iv) a brand new Appendix (Appendix B-1) with a quick creation to Ugi's idea of Constitutional Chemistry and to the courses EROS and IGOR has additionally been added.

9) the most advancements in CHAOS model 3.0 for Macintosh are: i) The unique numbering or canonical matrices, ii) new disconnections, that are extra selective, iii) in addition to earrings and SYNTHETICALLY major jewelry, the recent model provides, if required, the first earrings. different new recommendations are decide upon and RESIZE within the menu EDIT, wherein possible choose a part of a man-made series or resize the molecule drawing, iv) the prospect to introduce new disconnections from contained in the application CHAOS itself and paintings (if wanted) with one's personal chemistry, via CHAOSBASE. the purpose of this software is to create DATABASES of recent DISCONNECTIONS. Such DATABASES will be opened from this system CHAOS in this type of demeanour that it permits to disconnect molecules in response to the DISCONNECTIONS outlined within the DATABASE (instead of disconnecting in keeping with predefined ones applied in CHAOS).

10) error and error detected within the first version were corrected.
