What is the difference between the amino acid content of gelatin and casein?
Gelatin is the product of the denaturation of collagen. Collagen is a triple helical molecule that is composed nearly by one third of its residues with Glycine and a 15 to 30% of its residues by Proline and 4-hydroxyproline. When the collagen loses it's triple helix configuration, occurs gelatinization.On the other hand, Casein, the most abundant protein in milk, contains a fairly high number of Proline residues, which do not interact each other, there are no disulfide bridges in it's structure, and therefore it has relatively little tertiary structure.According to above, the main difference between gelatin (denatured collagen) and casein are the 4-hydroxyproline residues, that allow to collagen to form its characteristic triple helix.
What type of macromolecule is a collagen?
In the most simple sense, collagen is a protein. To be more specific, it is a polypeptide made up of of (3) amino acid based helices arranged in a triple right-handed helix, or coiled coil.
What protein is insoluble in water?
One example of a protein that is insoluble in water is collagen, which is a structural protein found in connective tissues such as skin, tendons, and bones. Collagen's insolubility in water is due to its triple helix structure and the presence of hydrophobic amino acid residues in its composition.
Explain why the quaternary structure of collagen makes it a suitable molecule for a tendon?
In hemoglobin, 4 subunits associate by noncovalent interactions.In collagen, three chains associate in a triple helix by noncovalent interactions and the triplet helices are covalently cross linked by a series of reactions including lysine residues being converted to hydroxylysine by the action of ascorbic acid (vitamin C). The loss of this reaction is the cause of connective tissue breakdown in scurvy.Do you have Mr. Peters?
What kind of bond is represented by three dashes between two atoms in the structural formula of a molecular compound?
A triple bond.

Is collagen a secondary or tertiary structure?
With most proteins, it has a secondary and tertiary structure.

How do find mass of a regular solid?
Use a digital mass scale or a triple-beam-balance scale to find the mass of a regular solid.

How does collagen helix differs from alpha helix?
A collagen helix is less compact (because it goes into triple helices), and it is a left-handed helix. An alpha helix is more compact and hence requires more rotation of bonds to form (hence proline is not very common...has an imidazole ring). It is a right-handed helix, and goes into double helices instead.
What does A2 width mean in a ladies shoe?
A2 width means a double narrow. A is a regular narrow A2 is double narrow and A3 is triple narrow. These are also just referred to as A, double A or triple A.

What is the proper way to tie ice skates?
Just like a regular shoe but don't forget to double or triple not it if you want.
