Best Answer: Membrane proteins can be divided into several categories: Integral membrane proteins which are permanently bound to the lipid bilayer. Peripheral membrane proteins that are temporarily associated with lipid bilayer or with integral membrane proteins. Lipid-anchored proteins bound to lipid bilayer bound through lipidated amino acid residues.
When one or more of these glands is infected, it is called parotitis. Submandibular glands are located on each side of your jaw below the jawbone. Sublingual glands sit on the bottom of your mouth under your tongue. Additionally, hundreds of small (minor) salivary glands deposit saliva from ducts around your mouth.
Print. The salivary glands produce saliva to moisten the mouth, to help protect teeth from decay and to digest food. The three major salivary glands are the parotid gland, submandibular gland (also called the submaxillary gland), and sublingual glands. Saliva drains into the mouth through small tubes called ducts.1  The parotid gland makes 25% of the saliva and drains into the mouth near the upper teeth.2  The submandibular gland makes 70% of the salvia and drains into the mouth from under the tongue.rint.
