alfaamyoláz

Alfa-amiláz is an enzyme that plays a crucial role in the digestion of carbohydrates. It is primarily found in saliva and pancreatic juice. The enzyme's main function is to hydrolyze alpha bonds of the polysaccharide starch, breaking it down into smaller sugar molecules like dextrins, maltose, and glucose. This process begins the breakdown of complex carbohydrates into simpler sugars that can be absorbed by the body.

There are different types of amylase, but alfa-amiláz is the most common form found in humans. Salivary amylase, also known as ptyalin, starts the digestion of starch in the mouth. Pancreatic amylase is produced by the pancreas and continues the digestion of starch in the small intestine. The activity of alfa-amiláz is pH-dependent, with optimal activity occurring in neutral to slightly alkaline conditions.

Elevated levels of alfa-amiláz in the blood can be an indicator of various medical conditions, particularly pancreatic disorders such as pancreatitis. It can also be elevated in other conditions affecting the salivary glands or in certain types of cancer. However, interpreting amylase levels requires careful consideration of other clinical factors and laboratory results. Diagnostic tests measuring alfa-amiláz levels are commonly used in clinical settings.
