Negatively charged amino acids are acidic bacause they gave a proton (H+) to the solution. The amino acid was not charged before it went into the solution, but lost a hydrogen when placed in water and became negativley charged. It also donated a proton to the solution so it is considered acidic. Similar logic applies with the basic amino acids.

How do you know if an amino is acidic?
If they are negatively charged above pH 3. These amino acids are aspartic acid and glutamic acid. In their ionized state, they are often referred to as aspartate and glutamate.
What is a small protein with a high proportion of positively charged amino acids that binds to the negatively charged DNA and plays a key role in it chromatin structure?
histone
Why the pH does affect the separation of amino acids by electrophoresis?
The separation of amino acids by electrophoresis is influenced by the pH because it affects the ionization state of the amino acids. At different pH levels, amino acids can exist in different forms (protonated or deprotonated), which affects their charge. Amino acids with different charges will migrate at different speeds during electrophoresis, leading to their separation.
Why amino acids exists as zwiter ion?
It is an ion with overall neutral charge.But in its chain , there exists two parts where one part has a negative charge and another side has an equal positive charge to nullify the negative charge. This ion becomes positively charged in acidic medium and negatively chargedin alkaline medium. Eg amino acids etc.
Amino acid as acids and bases?
Amino acids are organic molecules which proteins are build from. There are twenty. However there is two amino acids which are acidic: Aspartic acid and glutamic acid.
Why are acidic amino acids negatively charged and vice versa i thought adding H plus ions to make it acidic would make it positive?
Not when you donate those ions in solution as acids do.

Is glutamine acidic?
No. Glutamic acid and Aspartic acid are acidic amino acids while Histidine, Arginine and Lysine are basic amino acids.

Why do proteins denature?
A protein consists of amino acids. Some of these amino acids are polar, having positively charged sides and negatively charged sides. A change in PH simply means a change in the amount of (H+) atoms. As you can see these hydrogen atoms are positively charged, and attract the negative side of the polar amino acids. so a change in the PH changes the stability of a protein structure and can cause its denaturation.
Are amino acids true acids?
Nope. There are however two acidic amino acids: Aspartic acid and glutamic acid.

What kind of charge does protein have?
Proteins do have charges based on its amino acid content. there are polar uncharged and acidic, basic amino acids exist in the cells(Lysine, Arginine, asparic acid are a few charged groups). Based on the codes of mRNA proteins are formed by these amino acids in a sequence.
Are proteins acids?
hi dear.....! we cant say that proteins are always acidic. it depends on the kind of amino acids they are made up of. if it contains more acidic aminoacids , then it is acidic.
Which ion is part of every amino acid?
There are two ions present in every amino acid. There is a positively charged amino group and a negatively charged carboxyl group.
