Mucins (/ ˈ m juː s ɪ n /) are a family of high molecular weight, heavily glycosylated proteins (glycoconjugates) produced by epithelial tissues in most animals. [1] Mucins' key characteristic is their ability to form gels ; therefore they are a key component in most gel-like secretions, serving functions from lubrication to cell signalling ...
The major mucins secreted – MUC5AC and MUC5B - are large polymers that give the mucus its rheologic or viscoelastic properties. [7] [4] MUC5AC is the main gel-forming mucin secreted by goblet cells, in the form of threads and thin sheets. MUC5B is a polymeric protein secreted from submucosal glands and some goblet cells, and this is in the ...
These microorganisms include protists which use it for their locomotion, with the direction of their movement always opposite to that of the secretion of mucilage. [1] It is a polar glycoprotein and an exopolysaccharide. Mucilage in plants plays a role in the storage of water and food, seed germination, and thickening membranes
Although trichomes are used for protection, they can be disadvantageous for plants at times because trichomes may reflect light away from the plant that can be used to photosynthesize. [2] The cuticle is a layered structure of waxes and hydrocarbons located on the outer layer of the epidermis which also helps protect the plant from stress. [2]
The main role of goblet cells is to secrete mucus in order to protect the mucous membranes where they are found. Goblet cells accomplish this by secreting mucins, large glycoproteins formed mostly by carbohydrates. The gel-like properties of mucins are given by its glycans (bound carbohydrates) attracting relatively large quantities of water. [10]

The two main components of the gel are mucins and water, with the mucins forming the backbone of the mucous. [4] Mucin originates from the mucus secretions from submaxillary glands, which are salivary glands that are located under the floor of the mouth. The secreted mucin assists in digestion by coating the bolus such that it travels easily ...
This tissue system is present between the dermal tissue and forms the main bulk of the plant body. Parenchyma cells have thin primary walls and usually remain alive after they become mature. Parenchyma forms the "filler" tissue in the soft parts of plants, and is usually present in cortex, pericycle, pith, and medullary rays in primary stem and ...
