Abstract Qualitative chromatographic methods for the separation of free amino acids in table sirups are presented to aid in the development of chemical indices of composition which may be useful in establishing the identity of sirups and detecting their adulteration. Free amino acids in 2 table sirups were isolated on ion exchange columns and eluted with dilute ammonia. The concentrated amino acid mixture in the eluate was spotted directly on silica gel G plates for TLC analysis, or the amino acids were converted to their N-trifluoroacetyl n-butyl esters for GLC analysis. As many as 16 amino acids were qualitatively separated and identified and a potential for quantitative analysis was demonstrated.

Embryo Metabolism

Proline-U-14C injected into the endosperm of 3-day-old etiolated seedlings of Montcalm barley and its mutant was readily translocated to the embryo. Of label present in the embryo, over 65% was accounted for by protein and free amino acids and about 25% was present in organic acids. Proline accounted for over 90% of the label in free amino acids of the endosperm but accounted for less than 50% of label in this fraction in the embryo. Proline was readily converted to glutamate in the embryo. Metabolism of proline was similar in both lines.
