Why is X-ray radiation required in protein structure determination?
Protein structure determination is basically crystallography i.e. finding out the arrangements of atoms. This technique uses Diffraction maxima and minima to determine 3D structures. For diffraction to occur, the size of the obstacle must be close to the wavelength of light used. Since the obstacles in this case are molecules, we use X rays, whose wavelength is comparable to radius of molecules.
Is photoelectric effect an inelastic collision?
Yes definitely it is elastic since initial photon does not return with the same frequency or wavelength.
What is the effect of balanced pressures acting on an object?
Nothing... It doesn't move since the net force is equal to zero. I learned this in Science class today!
What is gravity if it is not a force?
Gravity really is one of the four main forces of the Universe. gravity is an effect and not the cause of anything, no gravitation's, no gravity waves, none of it. gravity is a dynamic effect. the acceleration of the underlying for of energy focused to the center of a mass. there is no separate force called gravity, just a dynamic effect we call 'gravity'
Who discover photo electric effect and what date?
The photo electric effect was explained by Einstein in 1905 when he theorized that light could transfer its energy like a particle and knock electrons out of metals. But the actual effect had been observed by a number of scientists since 1887, they just couldn't come up with a satisfactory theory that explained everything they observed. I believe he got the Nobel Prize for his photo electric effect theory, although he is more famous for his Relativity theories.
What is a tertiary protein structure exemplified by?
Hemoglobin - formed with alpha helices and/or beta sheets, but as one, contiguous polypeptide. Superoxide dismutase would be a good example of a quaternary structure protein, since it is made of more than one polypeptide chain.
How does the effect of freezing differ from the effect of boiling the enzyme?
Freezing doesn't effect the enzymes since freezing does not permanently affect enzyme structure. Boiling permanently changes the structure and can change the enzymes.
How is Protein Structure related to its function?
The structure of its active site relates to its function, since they have a certain degree of especificity towards substrates.
Which methods you can use to determine the primary structure of an enzyme?
Off the top of my head: techniques such as chemical and enzymatic degredation (particularly if they are targeted) coupled with various analytical techniques particularly mass spectrometry and NMR. X-ray crystallography could also be used if the enzyme can be crystallised.
How does protein denatured?
It breaks the hydrogen bonds and hydrophobic interactions between different parts of the protein molecule. Proteins are composed of amino acid subunits linked together by peptide bonds—this is called a polypeptide and is also known as the primary structure of a protein. The primary structure interacts with itself (also known as folding) forming hydrogen bonds and hydrophobic interactions with different parts of the same molecule. Heat disrupts the hydrogen bonds and hydrophobic interactions leaving the protein to unfold when it is heated. Since heat is not strong enough to break the peptide bonds between the amino acid subunits, the primary structure remains intact. Once the protein is cooled again, the hydrogen bonds and hydrophobic interactions can reform since they are based on the makeup of the primary structure and it hasn't changed. :) Hope this helps.
Are foods more filling if they are high in fiber or high in protein?
Fiber has the bulk to physically fill the stomach giving a full feeling. Protein provides a longer-lasting effect of satiation since it is used more slowly.

What does a protein have to have in order to work?
Since there are many different types of proteins, there are many different requirements for them to work in any system including the human body. A protein is made up of amino acid monomers, each of which must contain an amino group and an "R" group. Each protein has primary structure and secondary structure, and some haveQuaternaryand tertiary structures as well. Each specific protein must be at a specific temperature and pH to function properly, or they can become denatured.
Chemical denaturation of protein?
Denaturation of proteins involves the disruption and possible destruction of both the secondary and tertiary structures. Since denaturation reactions are not strong enough to break the peptide bonds, the primary structure (sequence of amino acids) remains the same after a denaturation process. Denaturation disrupts the normal alpha-helix and beta sheets in a protein and uncoils it into a random shape.Denaturation occurs because the bonding interactions responsible for the secondary structure (hydrogen bonds to amides) and tertiary structure are disrupted. In tertiary structure there are four types of bonding interactions between "side chains" including: hydrogen bonding, salt bridges, disulfide bonds, and non-polar hydrophobic interactions. which may be disrupted. Therefore, a variety of reagents and conditions can cause denaturation. The most common observation in the denaturation process is the precipitation or coagulation of the protein.
Why is Vishnu the Hindu god of preserving blue?
Hindu god vishnu is believed to be staying in the deepest parts of the ocean. Since ocean is blue Lord vishnu is associated with preserving blue.
Hemoglobin represents which level of protein organization?
Haemoglobin has a protein structure upto quarternary structure since it is a dimer made up of two monomeric units, each of which are two in number. Thus the overall structure has 4 monomeric units.
