The interaction between monostearin and amylose in an aqueous environment has been studied by Raman spectroscopy. A perdeuterated lipid was used to follow the C‐D stretching vibrations. The hydrocarbon chain conformation inside the amylose helix seems to be ordered as in the crystalline state, and the geometry of the amylose V‐form of this complex corresponds to nearly three turns of the helix per hydrocarbon chain. The maximal amount of monoglyceride in the complex (1: 5 monoglyceride: amylose) obtained experimentally, indicates that not the whole chain is in the average involved in complex formation.
