alfa1

Could you specify the intended context for "alfa1"? It can refer to multiple things across domains (for example, biology as a shorthand for alpha-1 subunits in proteins, technology as a project codename or product version, or other uses). Do you want a general disambiguation-style article covering common uses, or a focused article on a specific domain? If you prefer, I can proceed with a concise, neutral overview that outlines typical uses and notes variations.
