在快速脂肪分解过程中，在超离心的人类上肠内容物中发现了一种粘性的凝胶状相。这种“凝胶”相在超离心管中胶束和油相之间分层。凝胶含有胶束的典型脂质，而不是油相。这些脂质的浓度在凝胶阶段比胶束阶段更高，总胆盐与脂质的比例更低。凝胶，不像胶束相，是双折射的交叉偏振。这些数据表明，在脂肪消化过程中，这种凝胶相的脂质可以在肠道中形成液晶。
A viscous, gel-like phase was found in ultracentrifuged human upper intestinal contents collected during rapid fat lipolysis. This “gel” phase was layered in the ultracentrifuge tube between the micellar and oil phase. The gel contained lipids typical of the micellar and not the oil phase. The concentration of these lipids was higher and the ratio of total bile salts to lipids was lower in the gel than in the micellar phase. The gel, unlike the micellar phase, was birefringent between crossed polarizers. These data demonstrate that lipids in this gel phase can form liquid crystals in the gut during fat digestion.
