What type of bond can two cysteine form?
Two cysteine residues can form a covalent bond called a disulfide bond by oxidation of their thiol groups. This bond contributes to protein structure and stability, forming bridges between different regions of a protein or between different protein molecules.
Thiols can be gently oxidized to?
disulfides using oxidizing agents like hydrogen peroxide or iodine. This process is called disulfide bond formation and is important in stabilizing protein structures.
Do all viruses have protein coats?
yes
Which section of DNA that provides information for a protein is called a?
The section of DNA that provides information for a protein is called a gene. Genes contain the specific sequences of nucleotides that encode the amino acid sequences of proteins. When a gene is expressed, it undergoes transcription to produce messenger RNA (mRNA), which is then translated into a protein.
The final three dimentional shape of a protein is?
The final three-dimensional shape of a protein is known as its tertiary structure. This structure is determined by the interactions between amino acid side chains, such as hydrogen bonding, disulfide bonds, hydrophobic interactions, and electrostatic interactions. The tertiary structure is crucial for the protein's function and determines how it interacts with other molecules.
Does proteins contain phosphurous?
No protein do not contain phosphorous but DNA has. Protein may have sulfur containing amino acids that can form disulfide linkage. Proteins can be phosphorylated if it is a phosphoprotein by kinases.
What type of bond can two cysteine form?
Two cysteine residues can form a covalent bond called a disulfide bond by oxidation of their thiol groups. This bond contributes to protein structure and stability, forming bridges between different regions of a protein or between different protein molecules.
Why does cows milk contain protein?
the protein called casein is there to feed their young
Does hair contain protein?
Yes, hair contains a protein called keratin.
What is the term used for a change in a protein's three dimensional shape or confirmation due to disruption oh hydrogen bonds disulfide bridges or ionic bonds?
The term for a change in a protein's three-dimensional shape due to disruption of hydrogen bonds, disulfide bridges, or ionic bonds is called denaturation. This process can be caused by factors such as heat, pH changes, or chemicals, leading to loss of protein function.
The larger of the two filaments forming a cross-bridge is made of a protein called?
Myosin
Does animal fingernails contain protein?
Yes, it's called "Keratin".
What functional groups form disulfide bonds?
The functional group involved in forming disulfide bonds is the sulfhydryl group, which consists of a sulfur atom bonded to a hydrogen atom (-SH). In proteins, two sulfhydryl groups from cysteine amino acids can undergo a redox reaction to form a covalent bond called a disulfide bond (-S-S-), stabilizing the protein's structure.
What kind of molecule is a enzyme?
Many enzymes consist of a protein and a non-protein (called the cofactor). The proteins in enzymes are usually globular. This is the tertiary structure of a protein. These globular proteins include enzymes and immunoglobins. The structures are held in place by hydrogen bonds, disulfide bridges and ionic bonds.
Thiols can be gently oxidized to?
disulfides using oxidizing agents like hydrogen peroxide or iodine. This process is called disulfide bond formation and is important in stabilizing protein structures.
What is the functional three-dimensional form of a protein called?
The functional three-dimensional form of a protein is called its tertiary structure. This structure is formed by the folding and interactions of the protein's amino acid chain, which can involve hydrogen bonds, ionic bonds, hydrophobic interactions, and disulfide bridges. The tertiary structure is crucial for the protein's functionality, as it determines the active sites and overall shape necessary for its biological activity.
Is finger nails a lipid?
Actually, finger nails contain protein (called "keratin").
