Collagen classification and structure Evolutionary biology essay
Collagen types I and II, which cluster in the A clade, are the most common collagen types in vertebrates. The hemichordate and lancet collagen sequences in the A clade were found for their transcript abundance in EST studies, Lowe et al. 2003, Panopoulou et al. 2003, so it is likely that these sequences represent the major fibrillar ones. There are no hard and fast rules for structuring a college application essay, but you should plan and outline carefully to ensure that your essay flows smoothly and logically. Typical structural choices include: A series of vignettes with a common theme. one story that shows your positive qualities. Although many structures can function, the rise of multicellular animal diversity meant that cells joined together to form tissues and organs. The 'glue' that allowed the cells to work together is made of rope-like molecules called II. Classification of proteins based on biological functions: Catalytic protein: They catalyze the biochemical reaction in cells. E.g. Enzymes and Coenzymes 2. Structural Protein They make various structural components of living things. E.g. Collagen makes bones, elastin makes ligaments and keratin makes hair and nails. 3. Dietary Protein: Collagen is the natural fibrous protein that usually comes from the skins, bones and connective tissues of cows, pigs or amphibians. However, pork or bovine gelatin is prohibited for Muslim, Jewish and Hindu believers3, with the exception of fish-based products. Fish gelatin is extracted from solid fish waste, including fish bones, scales and skins. Taxonomy is the branch of biology that classifies all living things. It was developed by the Swedish botanist Carolus Linnaeus, who lived in the century, and his classification system is still used today. Linnaeus invented binomial nomenclature, the system for giving each type of organism a genus and species name. The triple helix was co-opted in the form of collagen IV to enable the evolutionary transition from unicellular organisms to multicellular animals, and the triple helix was also adapted to give rise to all other members of the diverse collagen superfamily, allowing the evolution of tissues and organs is made possible (Fig. 5B)..
