Gullet Size. The angle of the points, the shape of the panels, and the width of the gullet plate work together to create a specific gullet size, and that size in turn determines how the saddle sits on the horse.
Carbohydrates and proteins dissolve in water, which allows digestive enzymes to go to work on them, but fat does not. Your liver produces a substance called bile, which is secreted into the small intestine. This breaks up fat in a process called emulsification, which effectively make the fats water-soluble. Digestive enzymes in the small intestine can then break them down.
The digestive enzyme, lipase, is water soluble and can only work at the surface of fat globules. Digestion is greatly aided by emulsification, the breaking up of fat globules into much smaller emulsion droplets. Bile salts and phospholipids are amphipathic molecules that are present in the bile.mulsification and digestion. The key issue in the digestion and absorption of fats is one of solubility: lipids are hydrophobic, and thus are poorly soluble in the aqueous environment of the digestive tract.
