Abstract:
The evaluation of changes in the fatty acid composition in Lupinus species after the debittering process is crucial to determine their nutritional implications. The aim of this study was to evaluate changes in the fatty acid composition in Lupinus albus and L. mutabilis after the debittering process. Lupinus species showed different fatty acid compositions which changed depending on the debittering process applied. The debittering process changed the monounsaturated and polyunsaturated fatty acids in L. albus, whereas in L. mutabilis it changed the w-6/w-3 ratio. However, the total saturated fatty acid content remained stable in both species after the debittering process. The changes in L. albus were associated with the fatty acid desaturation and a conversion into unsaturated fatty acids, whereas in L. mutabilis with the lipid peroxidation by decreasing the linoleic acid content. Nutritional implications of these changes in the fatty acid composition are discussed.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Classifying Matter by Composition
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.
A mixture is composed of two or...
