Studies were made on low molecular weight components in the short chain triglyceride (SC-TG) fraction separated from crude lipids extracted from soybean seedlings of the fourth day, chiefly on the axis TG fraction.
Fatty acids (FA) in the subfraction of SC-TG were composed chiefly of C16 : 0, followed by C14 : 0, and less amounts of C18 : 0 and C18 : 1 (Table-5). Considerable numbers of oxygenated FA were found in the aldehydogenic fraction obtained by acid methanolysis of TG (Table-8). Aldehydes present in a subfraction of SC-TG were chiefly C14 : 0, followed by C16 : 0, C18 : 8, and C18 : 1 (Table-1). Diols found in TG and SC-TG subfractions were C2C9 (Tables-8 and 9).
The SC-TG fraction may be deviled into two main fractions : (1) A fraction comprising of com pounds such as short chain carbonyl compounds, alkanes, and alcohols with molecular weights less than 156 (Table-12); and (2) a fraction comprising of compounds such as TG having short chain FA and two types of diol derivatives, the diester type and 1-alkenyl ether ester type (Tables-13 and 14) with a molecular weight range of 470<600.
