Natural organic compounds analysis unit (NOCA)

NOCA Unit situates at Viikki campus at the Faculty of Agriculture and Forestry,  Department of Food and Environmental Sciences in two locations: Biocenter 1 and D-building (see picture and  map).

NOCA Unit co-operates with research groups from Faculty of Agriculture and Forestry, Faculty of Pharmacy and with other domestic and international research groups on the field of analysis and structural characterisation of small biomolecules.

NOCA Unit is specialised to analyze organic compounds from nature. These are microbial peptides and other secondary metabolites, biomolecules in food and in other biomaterials. Special knowledge of biological sample preparation and isolation, purification and characterisation of biomolecucules situates in NOCA Unit.

Services of NOCA Unit

Operation principle of the NOCA Unit:

As a general principle everybody are welcome to use the equipments of NOCA Unit or purchase analyses from the NOCA Unit. First a person have to agree with the operator and/or person in charge about the usage and usage times of the equipments. Operators familiarize the new users (students, researchers) before they can start the independent use of the equipments. Technical staff and operators are responsible of the maintenance of the analytical hardware.  Researchers or other users are primarily responsible of the analysis and interpretation of the obtained results.  In case of academic collaboration and in non-academic contract research all kind of arrangements are possible.

Analysis available

In D-building, available analysis include:

    • Analysis and characterisation of bioactive compounds
      • vitamins
      • lipids (polymers, neutral lipid classes, fatty acids)
      • lipid oxidation
      • plant sterols, sterol oxides
      • plant pigments, phenolics.
