A melting point of over 700 C and a density of less than 2 g/cm3 can be observed for many group 2 elements. In this group, the density increases on moving down the group, whereas the melting point increases upto calcium and then starts decreasing.
Calcium, symbol Ca is the element with melting point around 840 C and density of 1.55 g/cm3 which is closest to the specified data range .
During transpeptidation, nucleophilic attack occurs between the α-amine group in the A site and the esterified carbon in the P site
<h3>What is transpeptidation ?</h3>
A chemical process in which an amino acid residue or peptide residue is transferred from one amino compound to another. This process occurs when a protease reversibly converts one peptide to another.
- a process where one or more amino acids are transferred from one peptide chain to another, as in the case of a transpeptidase activity, or where a peptide chain itself is produced, as in the case of the production of a bacterial cell wall.
- Peptidoglycan glyco-syltransferases create the glycan strands (PGTs). The most popular class of antibiotics' fatal targets are enzymes termed transpeptidases (TPs), which produce the peptide crosslinks: using beta-lactams

Acetic acid is formed when wine is left exposed to oxygen for extended periods.
Answer: Strong bases are good electrolytes because they completely ionize in water.
Explanation:
Weak bases are those substances which dissociate partially to give ions when dissolved in water.
Strong bases are those substances which dissociate completely to give ions when dissolved in water.
Strong bases are good electrolytes as they completely dissociate to give ions which help in the conduction of electrical current.
Answer:
Covalent bonds are much more common in organic chemistry than ionic bonds. In covalent bonds, atoms share electrons, whereas in ionic bonds atoms transfer electrons. The reaction components of covalent bonds are electrically neutral, whereas for ionic bonds they are both charged.
