The presence of mineral surface for the amino acid to adhere to may have aided the polymerization of amino acids into peptides in the oceans of early prebiotic earth.

Amino acids are the building bocks of protein. The structure of an amino acid comprises of a carboxylic group, an amino group, a hydrogen atom and a variable R-group attached to the same alpha-carbon atom. There are 22 types of amino acids involved in the formation of proteins.

Prebiotic earth refers to the Earth that existed before the origin of life. The environment of earth was completely different from now. The temperature was extremely hot with no oxygen, abundant of water bodies and ionizing radiations from the space.
