The alpha 1 chain in type V collagen has a molecular weight of approximately 140 kDa.
The boiling points of alkenes depend on their molecular weight and structure. Generally, as the molecular weight of the alkene increases, so does its boiling point. Additionally, branching in the alkene structure tends to lower the boiling point compared to straight-chain alkenes of similar molecular weight.
To reduce the melt flow index of HDPE granules, you can increase the molecular weight of the polymer by using a higher molecular weight grade of HDPE, incorporating chain extenders or cross-linking agents, or blending with a lower molecular weight polymer. These methods can help decrease the flowability of the material, resulting in a lower melt flow index.
NMR isn't really used to determine molecular weight in general. It can be done for certain oligomers by, for instance, determining the ratio of end-group protons to protons that only occur in the "middle" of the chain.
Without the salt step, if you compounds do not react in stoichiometric proportions, chain termination can occur too quickly and limit molecular weight.
Haha wait are you in Amherst College biochemistry? What are the odds that 682 showed up on another college's problem set? Use 110 g/mol per amino acid (already corrected for the loss of water in amino acid condensation during formation of the protein) and multiply.
The alpha 1 chain in type V collagen has a molecular weight of approximately 140 kDa.
The weight average molecular weight of the polymer is the average of the molecular weights of all the polymer chains in the sample, taking into account the weight of each chain.
the basic structure of the immunoglobulin gene natural immunoglobulin molecule containing four heterologous polypeptide chain, in which the molecular weight known as the heavy chain and lower molecular weight light chain. Two H chains and two L-chain amino acids in the same natural Ig molecules are composed of exactly the same.
Molecular weight of a polymer depends rather on it's degree of polymerization (chain length) than on it's composition. Typical polymer molecular weights are in the range of 1000 to 1000 000 and beyond.
The amino acid side chain residues in an helix orient themselves outward from the center of the helix.
Simply looking at the expressions that derive weight average and number average one can see that the weight average is a second order expression where number average is a first order. To put it more simply: weight averaged molecular weight emphasizes heavy molecules more than light ones; number averaged molecular weight says a molecule is a molecule and counts them both equally.
The boiling points of alkenes depend on their molecular weight and structure. Generally, as the molecular weight of the alkene increases, so does its boiling point. Additionally, branching in the alkene structure tends to lower the boiling point compared to straight-chain alkenes of similar molecular weight.
Large organic molecules (macromolecules) are generally formed by condensation reactions between smaller molecules.Condensation means that a small molecule is formed from the atoms removed during the reaction. In cells, the small molecule is water, so the type of condensation reaction is dehydration.Examples:glucose + (chain of n glucose residues) forms chain of n + 1 residues + wateramino acid + (chain of n amino acid residues) forms chain of n + 1 residues + water
A polypeptide is a chain of amino acids linked by peptide bonds, with a molecular weight of up to about 10,000. It is composed of amino acids.
