  2. Salivary gland - Wikipedia

    en.wikipedia.org/wiki/Salivary_gland

    The two parotid glands are major salivary glands wrapped around the mandibular ramus in humans. [6] These are largest of the salivary glands, secreting saliva to facilitate mastication and swallowing, and amylase to begin the digestion of starches. [7] It is the serous type of gland which secretes alpha-amylase (also known as ptyalin). [8]

  3. Parotid gland - Wikipedia

    en.wikipedia.org/wiki/Parotid_gland

    Though the parotid gland is the largest, it provides only 25% of the total salivary volume. The serous cell predominates in the parotid, making the gland secrete a mainly serous secretory product. [10] The parotid gland also secretes salivary alpha-amylase (sAA), which is the first step in the decomposition of starches during mastication. It is ...

  4. Saliva - Wikipedia

    en.wikipedia.org/wiki/Saliva

    Saliva on a baby's lips. Saliva (commonly referred to as spit or drool) is an extracellular fluid produced and secreted by salivary glands in the mouth.In humans, saliva is around 99% water, plus electrolytes, mucus, white blood cells, epithelial cells (from which DNA can be extracted), enzymes (such as lipase and amylase), and antimicrobial agents (such as secretory IgA, and lysozymes).

  5. Amylase - Wikipedia

    en.wikipedia.org/wiki/Amylase

    The pancreas and salivary gland make amylase (alpha amylase) to hydrolyse dietary starch into disaccharides and trisaccharides which are converted by other enzymes to glucose to supply the body with energy. Plants and some bacteria also produce amylase. Specific amylase proteins are designated by different Greek

  6. AMY2A - Wikipedia

    en.wikipedia.org/wiki/AMY2A

    Amylases are secreted proteins that hydrolyze 1,4-alpha-glucoside bonds in oligosaccharides and polysaccharides, and thus catalyze the first step in digestion of dietary starch and glycogen. The human genome has a cluster of several amylase genes that are expressed at high levels in either salivary gland or pancreas.

  7. α-Amylase - Wikipedia

    en.wikipedia.org/wiki/Α-Amylase

    The test for amylase is easier to perform than that for lipase, making it the primary test used to detect and monitor pancreatitis. Medical laboratories will usually measure either pancreatic amylase or total amylase. If only pancreatic amylase is measured, an increase will not be noted with mumps or other salivary gland trauma.

  8. Digestive enzyme - Wikipedia

    en.wikipedia.org/wiki/Digestive_enzyme

    Amylase, produced by the salivary glands, breaks complex carbohydrates, mainly cooked starch, to smaller chains, or even simple sugars. It is sometimes referred to as ptyalin . Lysozyme : Considering that food contains more than just essential nutrients, e.g. bacteria or viruses, the lysozyme offers a limited and non-specific, yet beneficial ...

  9. Digestion - Wikipedia

    en.wikipedia.org/wiki/Digestion

    Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food. [1] The saliva also contains mucus, which lubricates the food; the electrolyte hydrogencarbonate (HCO − 3), which provides the ideal conditions of pH for amylase to work; and other electrolytes (Na +, K ...
