The Two Types of Fiber Fiber is classified by its affinity for water 1. Soluble fiber: dissolves in water and is fermented by intestinal bacteria Many are viscous, have thickening properties Move more slowly through GI tract Examples: Pectin in fruits and vegetables, beta-glucan in oats and barley, gums in legumes, psyllium 2.
Oleic acid is a fatty acid that occurs naturally in various animal and vegetable fats and oils. It is an odorless, colorless oil, although commercial samples may be yellowish. Oleic acid as its sodium salt is a major component of soap as an emulsifying agent.
Using your estimate of the volume of an oleic acid molecule, determine the number of. oleic acid molecules in 1 ml (cm3) of the acid. 5. The density of oleic acid is 0.9 g/ml. Using your value for the volume of a single oleic acid. molecule determine the mass of one molecule of the acid. 6. Now calculate the molecular weight of a mole of oleic acid molecules. 7. One mole (the molecular weight in grams) of oleic acid has a mass of 282 g.
