Why does milk and vinegar curdle when mixed?
Vinegar is a dilute acetic acid.ACID CURDLINGIn normal conditions milk has a pH of about 6.5-6.7 and at this pH value the casein is without protons, it has a negative charge and therefore the casein micelles are relatively soluble, because they repel each others. In an acid ambient milk coagulates, because casein has its isoelectric point at 4.6 pH, that is at this pH value it has a quantity of positive charges equal to the quantity of negative charges and the positive part of each "micelle" is attracted by the negative part of the others, causing the formation of ionic bonds among the "micelle" working against the dipole-dipole bonds with water, so that the protein precipitates in the form of demineralized casein and in the solution remain soluble calcium salts.
Is insulin water soluble?
yes, its a protein.
What are water soluble minerals?
water is a polar solvent.it contain slightly charges in either sides.specially in hydrogen side,it takes negative(-) charge and in oxygen side,it takes a positive (+)charge.so it is a polar solvent.ionic compounds disolve well in water than others.other polar solutes too disolve in polar solvents.
Which RNA was soluble rna?
The RNA molecules that attach the amino acid to the protein chain are usually soluble.
Why salt don't dissolve in water?
To understand why some salts don't dissolve in water, it's important to understand why those salts which are soluble do dissolve in water. Many types of salt are soluble in water, not just table salt (NaCl). Salts that dissolve in water are polar compounds. This means that one of the ends of the atom has a positive charge and the other side has a negative charge. These charges are normally strong enough to form an ionic bond and hold the molecule together. These charges are also what hold the molecules together into a crystalline structure. When the salt is put into water, the positive and negative charges of the water molecule pull the salt molecule apart into it's ions. In the case of NaCl, this would be the Na+ ion and the Cl- ion. The reason some salts don't dissolve in water is that they are not polar compounds. Since they aren't polar, the polar water molecules can't pull them apart into ions.
Why are many sulphate compounds soluble but some are not?
If you mean why are they soluble in water, it is because the hydrogen in water has a slight positive charge and the oxygen in water has a slight negative charge, making an ionic compound (such as one containing sulphate) which has charges itself, readily soluble to adjoin these charges.
Why does albumin and pepsin test positive for protein?
Albumin and pepsin are both proteins, the test for proteins was positive.
Are protein soluble in diluted Hydrochloric acid?
protein will have a net positive charge due to the protonation of all basic side chains (NH3+) in its structure therefore it will be soluble. If there is a charge at the protein surface, the protein prefers to interact with water, rather than with other protein molecules so makes it more soluble.
What is albumin in urinalysis?
Albumin refers to the amount of water soluble protein in the urine. A normal result would be negative.

yes, its a protein.
Why are ionic compounds souble in water?
Ionic compounds are made up of a positive cation (the metal) and a negative anion (the nonmetal). They are soluble in water because they can dissociate. The positive cations are attracted to the negative oxygen side of water molecules while the negative anions are attracted to the positive hydrogen side of water molecules. Water is a polar molecule and pulls the ions that make up the compound away from each other, thus causing the compound to be soluble.
Is protein soluble in acetone?
yes it is.
What is the medical term for simple soluble protein?
Albumin and globulin are simple soluble proteins.
When a soluble metallic salt is added to water its electrical conductivity decreases?
No. Its electrical conductivity increases because the positive and negative ions of the salt dissociate in the water.

What is the medical term meaning elastic soluble protein?
It is a protein that is stretchable during dissolutions.
