Answer:
there are four types of protein structure;
- primary
- secondary
- tertiary
- quatenary
Explanation:
A protein is a very large biological molecule composed of a chain of smaller molecules called amino acids. Thousands of different proteins are present in a cell, the synthesis of each type of protein being directed by a different gene. 
Determining the process by which proteins fold into particular shapes, characteristic of their amino acid sequence, is commonly called "the protein folding problem", an area of study at the forefront of computational biology. One approach to studying the protein folding process is the application of statistical mechanics techniques and molecular dynamics simulations to the study of protein folding. Protein folding enables them to perform different diverse functions.
Protein have a three-dimensional structure that enables them to perform diverse functions like transsport,structural support as building blocks and metabolic regulators as enzymes and hormones.
