The backbone of a polypeptide could be represented by?
The backbone of a polypeptide could be represented by a chain of nitrogen and hydrogen atoms. The polypeptide backbone is the key contributor to protein secondary structure, which involves backbone-to-backbone hydrogen bonding.
What is distinctive about primary vs secondary protein structure?
The primary structure of a protein is just an amino acid string; a polypeptide. The secondary structure of a protein is the hydrogen bonding of the side chains that form the polypeptide chain into alpha helices and beta sheets.
The primary structure of a folded protein is?
The simple polypeptide chain.
What chain is a sequence of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
What structure describes the alpha-helices and beta-sheets that are formed by hydrogen bonding vetween backbone atoms located near each other in the polypeptide chain?
This bonding is done in the secondary structure of the protein.
Hydrogen bonds between different parts of the polypeptide chain result in which level of protein structure?
Tertiary structure
The coiling of the protein chain backbone into an alpha helix is referred to as?
The coiling of the protein chain backbone into an alpha helix is referred to as the secondary structure. It is composed of several polypeptide chains.
What structure of a protein is the coiling or folding of a polypeptide chain?
Secondary structure. The coiling is the formation of the alpha helix. The folding is the formation of the beta sheets.
Secondary protein structure?
The secondary structure of protein:the ordered 3-d arrangements in localized area of a polypeptide chaininteractions of the peptide backbone (s-trans and planar)example of secondary structure : alpha-helix and beta-pleated sheet
The backbone of a polypeptide could be represented by?
The backbone of a polypeptide could be represented by a chain of nitrogen and hydrogen atoms. The polypeptide backbone is the key contributor to protein secondary structure, which involves backbone-to-backbone hydrogen bonding.
What is the teritary structure of a protein?
The tertiary structure of a protein is just how a polypeptide folds up into a "glob" or a "pretzel-like" shape. Primary structure determines secondary and tertiary structure of a protein. Usually a tertiary protein is held together Disulfide bonds like those found in a Cysteine residue.
What is the level of protein structure that describes all aspects of the three-dimensional folding of a polypeptide?
Primary: Simple string of amino acids called a polypeptide. Secondary: The varied hydrogen bonding of the side chains resulting in alpha helixes and beta sheets. Tertirary: The R group bondingd; hydophobic, hydrophilic, hydrogen bonding and disulfide bonding, which results in the globular, actual protein. Quarternary: The construction of multi protein subunits from tertiary structure. Such as hemeglobin.
What is distinctive about primary vs secondary protein structure?
The primary structure of a protein is just an amino acid string; a polypeptide. The secondary structure of a protein is the hydrogen bonding of the side chains that form the polypeptide chain into alpha helices and beta sheets.
What chain is sequences of amino acids that is the foundation for the basic structure of a protein?
polypeptide chain
Globular or fibrous polypeptide chains are what type of protein structure?
Tertiary structure.
Proteins differ from one another because?
Because the number of amino acids and their exact sequence in the polypeptide chain is different for each protein; this is called the primary structure, and it determines the secondary structure of the protein - the unique three-dimensional shape that the protein can fold into.
What can form a structure such as a helix or a sheet?
A polypeptide chain, which is the primary structure of a protein, can fold into secondary structures such as an alpha-helix or a beta-sheet.
