They are solid, thinner filament structures (6-8 nm, in diameter) composed of a double-helical polymer of the protein actin. And microfilaments play a key role of in virtually all types of contractility and location of cells as well as motility within cells

Pasta Cooking quality of pasta Pasta is the collective term used to describe Particle size of the semolina is an important products such as macaroni, spaghetti, vermicelli, characteristic: it is recommended that at least 90% noodles etc. which are traditionally made from of the particles should fall between 150 pm and the semolina milled from hard durum wheat (T. 340 pm in size. Particles larger than 340 pm durum) (cf. p. 154 for milling of semo). The impede the activity of enzymes in the dough
