AlphaFold is the most advanced system to date that can accurately predict a protein's 3D structure from its amino acid sequence. [30] The protein folding problem first began to emerge around the 1960s and ever since, scientists have struggled in determining methods to precisely predict the way a protein will fold solely based on the amino acid ...
The hydrophobic-polar protein folding model is a highly simplified model for examining protein folds in space. First proposed by Ken Dill in 1985, it is the most known type of lattice protein: it stems from the observation that hydrophobic interactions between amino acid residues are the driving force for proteins folding into their native state.

Predicting three-dimensional structure model of protein molecules from amino acid sequences. MOE: Molecular Operating Environment (MOE) is an extensive platform including structural modeling for proteins, protein families and antibodies [35] SBL: The Structural Bioinformatics Library: end-user applications and advanced algorithms BALLView
An alpha-helix with hydrogen bonds (yellow dots) The α-helix is the most abundant type of secondary structure in proteins. The α-helix has 3.6 amino acids per turn with an H-bond formed between every fourth residue; the average length is 10 amino acids (3 turns) or 10 Å but varies from 5 to 40 (1.5 to 11 turns).
The primary structure of a protein, its linear amino-acid sequence, determines its native conformation. [11] The specific amino acid residues and their position in the polypeptide chain are the determining factors for which portions of the protein fold closely together and form its three-dimensional conformation.

An example of distributed computing (Rosetta) in predicting the 3D structure of a protein from its amino-acid sequence. The predicted structure (magenta) of a protein is overlaid with the experimentally determined crystal structure (blue) of that protein. The agreement between the two is very good.
