What,re amino acids?

• There are more than 300 amino acid but these 20 amino acids are common in all animals.
• Amino acids are made up of amino group NH3 and carboxyl group COOH.
• Amino acids are the building block of protein and are linked by peptide linkage.
• Two amino acid released water H2O, carboxyl group of first amino acid release hydroxyl ion and amino group of second amino acid release hydrogen ion then hydroxyl ion and hydrogen ion react with each other to form water and when water release from amino acids peptide linkage is form.
• The general formula of amino acid is;

  ──NH2──CH──COOH
  	│
  	R

  here -NH2 is amino group and COOH is carboxyl group.
• Amino acids are divided into four groups;

1. Non-polar amino acid
2. Polar Amino acid
3. Acidic amino acid
4. Basic amino acid
