Abstract: A plurality of MRM transitions to be used to monitor a sample are received and divided into two or more contiguous groups. At least one sentinel transition is selected in each group that identifies a next group of the two or more contiguous groups that is to be monitored. A first group of the two or more contiguous groups is placed on a duty cycle list of the tandem mass spectrometer. One or more compounds are separated from the sample and ionized, producing an ion beam. A series of MRM transitions read from the duty cycle list are executed on the ion beam by the tandem mass spectrometer. When at least one sentinel transition of the first group is detected, a next group identified by the sentinel transition is placed on the list.

Abstract: The invention relates to a new isolated polysaccharide originating from Streptococcus thermophilus comprising the following repeat structure, and which may be use for the preparation of a food, cosmetic or pharmaceutical composition intended for inhibiting .beta.-galactoside specific lectins.

Abstract: The invention relates to a new isolated exo-polysaccharide originating from Streptococcus thermophilus consisting of essentially D-galactose, L-rhamnose and D-glucose in a molar ratio of 3:2:1, and optionally consisting of the following repeat structure. This polysaccharide may be used in flavor reactions, and for the preparation of a food, cosmetic or pharmaceutical composition intended for inhibiting .beta.-galactoside specific lectins.

Abstract: The present invention concerns a new branched natural soluble polysaccharide comprising a main chain having repeating side chains which are only made of lactose units, possibly substituted.The present invention also concerns the microorganism by which this branched polysaccharide may be obtained and the food composition, the cosmetical composition and the pharmaceutical composition comprising said branched polysaccharide and/or microorganism.
