DL-Norleucine (2-aminohexanoic acid). Use 65 g (0.33 mol) of 2-bromo-hexanoic acid (Expt 5.164) and 400 ml of concentrated ammonia. Ensure that the bung is securely wired to the reaction bottle and allow the latter to stand in a warm place (50-55 °C) for 30 hours. Filter the amino acid at the pump and keep the filtrate (A) separately. Wash the amino acid well with methanol to remove the ammonium bromide present. Concentrate the filtrate (A) almost to dryness and add 150 ml of methanol. A second crop of amino acid contaminated with ammonium bromide is thus obtained wash it with methanol and recrystallise from hot water, thus affording a further 6 g of pure dl-norleucine. The total yield is 28 g -(65%) the decomposition point is about 325 °C.

Karahdian et al. (1985a,b) demonstrated the production of l-octen-3-ol, 8-nonen-2-one, 3-octanone, 3-octanol and octanoic acid from linoleic acid and linolenic acid. The use of microbially produced fatty acids for characterization of mold fungi has been suggested (Blomquist et al., 1992). Lipolysis of triglycerides or amino acids may lead to the production of compounds such as 2-methylpropanoic acid, butanoic acid, 2-methylbu-tanoic acid, pentanoic acid, hexanoic acid and octanoic acid (Jolivet and Belin, 1993). The presence of different lipids and lipases in different fungi (Ha and Lindsay, 1993) and under different environmental conditions may explain a great deal of the variation in the volatile compounds produced. 

In contrast to the streptomycin-neomycin group of antibiotics, the members of the streptothricin group are not composed solely of carbohydrate moieties. In addition to the 2-amino-2-deoxy-D-guIose, the molecules contain one or more units of the unusual amino acid 3,6-diamino-hexanoic acid (jS-lysine) (10) together with a heterocyclic guanidine... 

Reflect and t ply Proteins contain methionine but not a-amino-> r hexanoic acid. The only structural difference is the substitution of —CHj— for —S—. Both groups are similar in size and hydrophobic character. Why is methionine more advantageous than a-amino-n-hexanoic acid ... 

In addition to the enzymatic pathway of aroma formation, a thermal route also exists. At high temperatures, interactions of amino acids and sngars resnlt in the formation of various aldehydes. After thermal treatment, the tea becomes more tasty and pleasant, and has a better aroma. An essential source of secondary volatiles, formed during tea leaf processing, is oxidative. o-Quinone resulting from the oxidation of catechins can oxidize, besides amino acids and carotenes, unsaturated fatty acids as well. Linoleic and linolenic acids can be converted into hexenal and trans-hex-2-enal, respectively, and in addition, small amounts of other volatile compounds, especially hexanoic acid and trani-hex-2-enoic acid, can be formed from the same acids, respectively. Also the monoterpene alcohols, linalool and geraniol, play an important role in the formation of the aroma of black tea [38]. 

We have developed a direct and noninvasive method to determine Tg of polymers at the interface with solid substrates [54, 55]. The strategy is to use fluorescence lifetime measurements using evanescent wave excitation. Figure 15a shows PS-NBD, i.e., PS containing the dye 6-[A-(7-nitrobenz-2-oxa-l,3-diazol-4-yl)amino]hexanoic acid (NBD) [55]. The NBD fraction of PS was sufficiently low to avoid self-quenching of the dye. The NBD dye was excited with the second-harmonic generation of a mode-locked titanium sapphire laser equipped with a...
