Secondary structure

Task 2a - Explain the tertiary structure in detail ;consider protein shape, bonds involved, how these bonds are made (groups involved, location) give an example of protein having this structure. The primary and secondary structures are both present in a tertiary structure, the whole chain may then be folded further to give the protein molecule a complex globular shape that is known ate the tertiary structure. Similarly to the secondary structure the tertiary structure of protein is determined by a sequence of amino acids in the polypeptide chain. (Inge B et al, 2001 page 45) This means that the tertiary structure refers to the overall three dimensional shape of a polypeptide chain. As seen in the image below. Proteins are classified into…

In addition, both proteins have one large interface between subunits and one smaller interface between them. The subunits of both proteins are in fact made of domains, however, the types of domain differ. Furthermore, the secondary structure of hemoglobin consists of only alpha helices, while that of phosphofructokinase consists of both alpha helices and beta sheets. Furthermore, these two proteins also share their ability for allosteric binding and cooperativity in the protein caused by the…

1. Most aquaporins have a similar structural arrangement, consisting of a similar fold. This fold contains helices encasing a small water-conducting channel where water is able to arrange in a singular line. There are cytoplasmic and extracellular loops immersing into the membrane through opposing sides, and form two smaller helices creating a psedo transmembrane segment. Within the membrane, there are four aquaporin molecules forming a homo-tetramer, creating a fifth channel; the channel is…

A protein has a precisely defined amino acid sequence which gives rise to its three dimensional structure which is essential to the protein’s function. These amino acids interact with one another to produce a specific folding pattern that produces the conformation of the protein. When one looks at the progression a protein makes in its folding complexity, it is clear that the folding is driven by the amino acid sequence alone. To understand this concept it is best to start with the primary…

Compare and Contrast Macromolecule Structures- How Structure Pays for Function Macromolecules provide essential functions to life, including structural support, a source for stored fuel, an ability to store and retrieve genetic information, among many others. The similarities and differences between the primary, secondary, tertiary, and quaternary structures of proteins, membranes, and nucleic acids are critical in understanding biological processes. Nucleic acids and proteins have analogous…

My type of molecule, Proteins should be the MVP because they protect the body, help to create new molecules, give structure to many parts of the body, send messages, and they transport and store molecules and cells. The first characteristic of my molecule is its solubility. Keratin is insoluble to water this is why keratin waterproofs the skin. The second property of Keratin is it’s luster, keratin is shiny. The third characteristic of keratin is it’s texture, the texture of keratin is hard…

part of a society founded and maintain by a scheme of docile bodies. Mainly focused in the control of the human body, the structure emphasizes in turning the body into an obedient machine that will serve the necessities of a given civilization. Philosopher Michael Foucault describes this scheme, composed by three main techniques: “the scale of the control, the object of the control and the modality”(Foucault, pp. 331-332). Although the explanation of this scheme is presented in terms of military…

fatty acid is a long carbon chain and it capped by carboxyl group.fatty acids are like acetic acid but fatty acid does not have long carbo with glycerol lto form triglyceride.fatty acids gives a major role in metabolic fuel and it important to a n chain like acetic acid.if wewant to make normal fat we have to combine 3 fatty acids with glycerol lto form triglyceride.fatty acids gives a major role in metabolic fuel and it important to all the membrane and gene regulator. it used in industrial…

4.3. The third dsRBD of Xlrbpa (xl3) is a protein/protein dimerization domain The strongest interacting partner from a two-hybrid screen with Xlrbpa turned out to be Xlrbpa itself. Two-hybrid assays with deletion constructs together with coimmunoprecipitation experiments identified xl3 but neither xl1 nor xl2 as a dimerization domain (Fig. 18, 19 and 20). Xl3 enhances the PKR antagonistic ability of Xlrbpa as previously indicated and discussed. The third domains of PACT and RAX, the human and…

etc. Protein-protein interaction plays an important role in functioning of body’s significant mechanism such as replication, transcription, translation, signal transduction, cell cycle, etc. Thus, proteins clusters together in a network map linking together various amino acids by peptide bond forming a three-dimensional structure. The entire map showing events of protein interactions that can occur in a living organism is called the interactome…
