Answer:
amino group
Explanation:
There are twenty (20) amino acids in nature. Generally, each amino acid is structurally made up of a central carbon atom called alpha carbon attached to a hydrogen, carboxylic acid group (-COOH) and an amine group (-NH2). However, one particular amino acid called PROLINE posseses an exception to this.
Proline, which is the only cyclic amino acid, is also the only amino acid that forms a secondary amine group i.e. loss of hydrogen atoms in its amine group when in a protein structure. This means that when in a protein, PROLINE does not have an AMINE GROUP.

Answer:</h3>
5.0 × 10^21 atoms of sulfur
<h3>
Explanation:</h3>
We need to know that 1 mole of an element contains atoms equivalent to the Avogadro's number.
Therefore;
1 mole of an element = 6.022 × 10^23 atoms
Thus, 1 mole of sulfur = 6.022 × 10^23 atoms
But, molar mass of sulfur = 32.065 g/mol
This means;
32.065 g contain 6.022 × 10^23 atoms
Therefore, 2.66 g of Sulfur will contain;
= (2.66 g ÷ 32.065 g/mol) × 6.022 × 10^23 atoms
= 5.0 × 10^21 atoms
Ka and Kb values of weak acids and weak bases are small.
This is because weak acids and weak bases do not dissociate completely, favoring the reactants more than dissociating into the product of H+ or OH-.
Answer:
Alpha decay forms new element with two fewer protons and two fewer neutrons; Beta decay forms new element with one more proton and one fewer neutron.
