Stamen is the Latin word meaning "thread" (originally thread of the warp, in weaving). [8]Filament derives from classical Latin filum, meaning "thread" [8]; Anther derives from French anthère, [9] from classical Latin anthera, meaning "medicine extracted from the flower" [10] [11] in turn from Ancient Greek ἀνθηρά (anthērá), [9] [11] feminine of ἀνθηρός (anthērós) meaning ...
Birch species are generally small to medium-sized trees or shrubs, mostly of northern temperate and boreal climates. [4] The simple leaves are alternate, singly or doubly serrate, feather-veined, petiolate and stipulate. They often appear in pairs, but these pairs are really borne on spur-like, two-leaved, lateral branchlets. [5]
Actin is a family of globular multi-functional proteins that form microfilaments in the cytoskeleton, and the thin filaments in muscle fibrils.It is found in essentially all eukaryotic cells, where it may be present at a concentration of over 100 μM; its mass is roughly 42 kDa, with a diameter of 4 to 7 nm.
Accessory proteins including motor proteins regulate and link the filaments to other cell compounds and each other and are essential for controlled assembly of cytoskeletal filaments in particular locations. [26] A number of small-molecule cytoskeletal drugs have been discovered that interact with actin and microtubules. These compounds have ...
In biology, a protein filament is a long chain of protein monomers, such as those found in hair, muscle, or in flagella. [1] Protein filaments form together to make the cytoskeleton of the cell. They are often bundled together to provide support, strength, and rigidity to the cell.
The split fibers and the size of the individual filaments make the cloths more effective than other fabrics for cleaning purposes. The structure traps and retains the dirt and also absorbs liquids. Unlike cotton, microfiber leaves no lint , the exception being some micro suede blends, where the surface is mechanically processed to produce a ...
Intermediate filaments (IFs) are cytoskeletal structural components found in the cells of vertebrates, and many invertebrates. [1] [2] [3] Homologues of the IF protein have been noted in an invertebrate, the cephalochordate Branchiostoma. [4] Intermediate filaments are composed of a family of related proteins sharing common structural and ...
Not to be confused with fibers or filaments, fibrils tend to have diameters ranging from 10 to 100 nanometers (whereas fibers are micro to milli-scale structures and filaments have diameters approximately 10–50 nanometers in size). Fibrils are not usually found alone but rather are parts of greater hierarchical structures commonly found in ...
