What structural level of a protein most affected by a disruption in hydrogen bonding?
The structural level of a protein is most affected by disruption would be the secondary structure. It is within the secondary structure where the folding and coiling of the protein is stabilized by hydrogen bonds.
What is the most common fixative used in haematology?
The most common fixative used in hematology is formalin. It helps to preserve cellular structures and prevent degradation of cells for further analysis under the microscope.
How is tertiary protein structure dependent on primary protein structure?
The relationship between the primary and tertiary structure of a protein is the both have a sequence of amino acids in a polypeptide chain.orThe sequence of amino acids in a primary structure determines its three-dimensional shape ( secondary and tertiary structure)
Is collagen a secondary or tertiary structure?
Collagen is a primary protein structure, composed of three polypeptide chains that form a unique triple helical structure. This triple helical structure is considered the primary structure of collagen.
What is an alpha helix?
Hi, The DNA Helix is simply another name for DNA, and such name is used because DNA is in a double helix shape. The DNA is what determines who you are and therefore is found in every cell in our body. It is the genetic information of a human being and it contains genes, which are what determines our traits. For example, there are genes that control eye color, hair color, size of body...etc.
What structural level of a protein most affected by a disruption in hydrogen bonding?
The structural level of a protein is most affected by disruption would be the secondary structure. It is within the secondary structure where the folding and coiling of the protein is stabilized by hydrogen bonds.
The shape of most protein molecules may be described as?
The shape of most protein molecules may be described as a specific three-dimensional structure, typically categorized into primary, secondary, tertiary, and quaternary structures. These structures are formed by the folding and interactions of the protein's amino acid sequence, creating a functional and unique shape that determines the protein's biological function.
What are proteins secondary structures?
Unlike the primary structure, the secondary structure is defined as the local conformation of the protein's backbone. Protein secondary structures are grouped in three major types: helices (being the most common the alpha helices), pleated sheets (also called beta structures), and turns.The combination of these three kind of secondary structures give a wide variety of forms of the protein molecules. These combinations are named supersecondary structures or motifs and occur in many unrelated globular proteins. As examples of motifs found in protein structures are: a) the beta-alpha-beta motif, the most common supersecondary structure (consists in a right-handed cross-over connection between two consecutive parallel strands of a beta sheet by an alpha helix); b) the beta hairpin motif, that consists of an antiparallel beta sheet formed by sequential segments of polypeptide chain that are connected by relatively tight reverse turns; c) the alpha-alpha motif, two successive antiparallel alpha helices pack each other with their axes inclined (one common protein with this structure is the alpha keratin); and d) the beta barrels, that are extended beta sheets that often roll up.
What are 4 levels of protein?
Primary_structure: the Peptide_sequence.Secondary_structure: regularly repeating local structures stabilized by Hydrogen_bond. The most common examples are the Alpha_helix, Beta_sheetand Turn_(biochemistry). Because secondary structures are local, many regions of different secondary structure can be present in the same protein molecule.Tertiary_structure: the overall shape of a single protein molecule; the spatial relationship of the secondary structures to one another. Tertiary structure is generally stabilized by nonlocal interactions, most commonly the formation of a Hydrophobic_core, but also through Salt_bridge_(protein), hydrogen bonds, Disulfide_bond, and even Post-translational_modification. The term "tertiary structure" is often used as synonymous with the term fold. The Tertiary structure is what controls the basic function of the protein.Quaternary_structure: the structure formed by several protein molecules (polypeptide chains), usually called Protein_subunitin this context, which function as a single Protein_complex.
What level of protein structure does a a-helix?
Some parts of a protein can have a helical structure - one of the most common secondary structures in proteins is the alpha helix.However, helix - especially double helix - will probably be more often used in the description of DNA, so be careful not to mistake the two.

Perhaps the most common enzyme on earth is?
RuBisCO is the most common protein on Earth. This protein is an enzyme.
Most abundant protein dead epidermal structures?
keratin
What is the most common protein produced by transgenic organisms?
The most common protein produced by transgenic organisms is insulin.
What is the protein coat that surrounds a virus called?
The protein coat surrounding the nucleic acid of a virus is called the capsid. These are broadly classified according to their structures. Helical (cylindrical) and icosahedral (spherical) are the most common types.
What is the most abundant protein in dead epidermal structures such as hair and nail called?
The most abundant protein in dead epidermal structures is called keratin. It is a fibrous protein that forms the main structural constituent of hair, feathers, hoofs, claws and horns.
What is the most common source of protein for an animal?
Depends, but a carnivore will get most of their protein from its prey.
