Answer: The secondary structure of protein is creates by hydrogen bonds between the hydrogen atoms on the amine group and the oxygen atom on the carboxyl group.
Explanation:
Secondary structure of protein is a three dimensional type of protein that is formed by hydrogen bonds between the hydrogen atoms on the amino group and oxygen atom on the carboxyl group. The secondary structure of protein chains are organised into two regular structures which are alpha helixes and beta pleated sheets. In alpha helix the chain is like a loosely coiled spring and beta pleated sheets, the chains are folded. Meanwhile, protein have three types of structures which are primary, secondary and Tertiary.
