Which Best Describes the Tertiary Structure of a Protein

There are several types of bonds and forces that hold a protein in its tertiary structure. Secondary structure indicates regions of ordered structure and tertiary structure is.

Levels Of Protein Organization

Amino acids linked by peptide bonds.

. After the amino acids form bonds secondary structure and shapes like helices and sheets the structure can coil or fold at random. According to this question the tertiary structure of the protein is formed as a result of the interaction of different R groups with one another and their environment. This is what we call the tertiary structure of proteins.

Alpha helix and beta pleated sheet. B Primary- hydrogen bonds Secondary- covalent bonds. The tertiary structure of a protein is dependent on ligand binding A given protein may have separate binding sites for several different ligands Ligands catalyse biological reactions The binding of the ligand results in the inactivation of the protein.

Hydrophobic interactions greatly contribute to the folding and shaping of a protein. Which of the following best describes the tertiary structure of a protein. Which of these best describes the types of bonds that stabilize each level of protein structure.

Tertiary Structure refers to the comprehensive 3-D structure of the polypeptide chain of a protein. Which of the following statements best describes the tertiary structure of a protein. The secondary structure is a helix or pleated sheet mad eof hydrogen bonds between the carboxyl and amino groups.

You are already familiar with this hierarchy because the most useful starting point for teaching basic protein structure is this structural grouping. Biology questions and answers. The R group is one of the four parts of the amino acid structure which is different for all amino acids.

Protein structure is stabilized by different types of bonds. Linderstrom-Lang 1952 in particular first suggested a hierarchy of protein structure with four levels. A Primary- peptide bonds Secondary- hydrogen bonds Tertiary- disulfide bridges Van der Waals interaction and ionic bonds.

The tertiary structure is a single polypeptide chain that forms a globular shape bonded by hydrogen ionic disulfide and van der Waals bonds or hydrophobic interactions and the interaction between R-groups. The structure formed from interactions between the amino acid side groups. Click card to see definition.

Tertiary structure of a protein describes A The order of amino acids B Location of disulphide bonds C Loop regions of proteins D The ways of protein folding. Specific biological activities such as enzyme activity are associated with the tertiary structure. Primary structure refers to the order of the amino acids in a protein.

Which of the following best describes the tertiary structure of proteins. The polypeptide chain may undergo coiling and folding to produce the tertiary structure. 09 Which of the following descriptions best describes the tertiary structure of proteins.

3D globular structures stabilized by covalent disulfide bridges. For instance in globular proteins the polypeptide chains are held together in a definite way forming a compact structure. Hemoglobin is a globular protein composed of a single polypeptide chain that has one O 2 binding site.

The tertiary structure consists of eight beta-strands connected by α-helices known as the globin fold Hemoglobin is a tetramer composed of two different types of globin subunits each of which has an O 2 binding site. The structure formed from interactions between the amino acid side groups is the best statement that describes the tertiary structure of a protein. This is the structure that gives protein the 3-D shape and formation.

To some extent the tertiary structure is determined by the amino acid sequence of the primary structure. Tap card to see definition. Which of the following describes the tertiary structure of proteins.

Orders of protein structure. Summary of Protein Structure. The tertiary structure of a protein is the set of angles contacts and conformations of all the atoms of a polypeptide chain that give rise to the folding of said polypeptide.

Linear protein folded into alpha helices and beta- pleated sheets. A-Characteristic patterns such as helices and sheets that arise when hydrogen bonds form between the amino acids of polypeptides b-The association of multiple polypeptides c-The linear sequence of amino acids making up the polypeptide d-Interactions between different. Primary secondary tertiary and quaternary.

The R group of the amino acid is either hydrophobic or hydrophilic. Central secondary tertiary and quaternary. Two or more polypeptide chains interacting to form a higher-order structure.

A linear chain of amino acids held together by covalent bonds. The tertiary structure is maintained by many. Several polypeptides held together by ionic polar or covalent bonds.

Which of the following best describes a feature of proteinligand interactions. These structures are stabilised by the several types of bonds namely hydrogen bond ionic bond van der waals interaction covalent bond disulphide bridges and. A single polypeptide chain folded into a three-dimensional shape by ionic polar or covalent bonds.
