What is a Primitive Solid? A primitive solid is a âbuilding block' that you can use to work with in 3D. Rather than extruding or revolving an object, AutoCAD has some basic 3D shape commands at your disposal. From these basic primitives, you can start building your 3D models.
Fats typically provide more than half of the body's energy needs. Fat from food is broken down into fatty acids, which can travel in the blood and be captured by hungry cells. Fatty acids that aren't needed right away are packaged in bundles called triglycerides and stored in fat cells, which have unlimited capacity.
Fatty acids have many functions in the body, and play a role in: 1  oxygen transport throughout the body. 2  providing energy (when glucose, a form of sugar, is not available). 3  development of strong tissues and organs. 4  brain functioning. 5  lowering cholesterol and reducing risk of heart disease.
