Atherosclerosis. Digestion of these compounds begins in the stomach, which contains acid-stable lipases that release some free fatty acids from dietary triacylglycerols. biochemistry and molecular biology department Concept Lipids are substances that are insoluble or immiscible in water, but soluble in organic solvents.. Fats (Triglyceride or triacylglycerole). 02 - Pharmacokinetics. Cholesterol • is a maternal molecule of all steroids in human body • is a starting molecule for synthesis of bile acids and steroid hormones (sex hormones, gluco- and mineralocorticoids) • is a component of plasma membranes.
