Type III Collagen is a homotrimer, or a protein composed of three identical peptide chains (), each called an alpha 1 chain of type III collagen.Formally, the monomers are called collagen type III, alpha-1 chain and in humans are encoded by the COL3A1 gene.Type III collagen is one of the fibrillar collagens whose proteins have a long, inflexible, triple-helical domain.
Type II collagen is the basis for hyaline cartilage, including the articular cartilages at joint surfaces. It is formed by homotrimers of collagen, type II, alpha 1 chains. It makes up 50% of all protein in cartilage and 85–90% of collagen of articular cartilage. Type II collagen is organised into fibrils. This fibrillar network of collagen ...
A representation of the 3D structure of the protein myoglobin showing turquoise α-helices. This protein was the first to have its structure solved by X-ray crystallography. Toward the right-center among the coils, a prosthetic group called a heme group (shown in gray) with a bound oxygen molecule (red). Proteins are large biomolecules and ...
Structure of a typical L-alpha-amino acid in the "neutral" form Amino acids are organic compounds that contain both amino and carboxylic acid functional groups.[1] Although over 500 amino acids exist in nature, by far the most important are the 22 α-amino acids incorporated into proteins.[2] Only these 22 appear in the genetic code of life.[3 ...
Vitamin B12, also known as cobalamin, is a water-soluble vitamin involved in metabolism.[2] It is one of eight B vitamins. It is required by animals, which use it as a cofactor in DNA synthesis, and in both fatty acid and amino acid metabolism.[3] It is important in the normal functioning of the nervous system via its role in the synthesis of ...
Platypus anatinusShaw, 1799. The platypus ( Ornithorhynchus anatinus ), [3] sometimes referred to as the duck-billed platypus, [4] is a semiaquatic, egg-laying mammal endemic to eastern Australia, including Tasmania. The platypus is the sole living representative or monotypic taxon of its family Ornithorhynchidae and genus Ornithorhynchus ...
Nattō ( 納豆) is a traditional Japanese food made from whole soybeans that have been fermented with Bacillus subtilis var. natto. [1] . It is often served as a breakfast food with rice. [2] . It is served with karashi mustard, soy or tare sauce, and sometimes Japanese bunching onion.
