There are two main things that can alter the secondary structure: α-helix: N-H groups in the backbone form a hydrogen bond with the C=O group of the amino acid 4 residues earlier in the helix.

Proteins have four levels of structure: primary (amino acid sequence), secondary (local folding patterns like alpha helices and beta sheets), tertiary (overall 3D shape), and quaternary (assembly of ...

Amino acids are organic compounds that serve as the fundamental building blocks of proteins. They play a crucial role in the structure, function, and regulation of the body's tissues and organs. Amino ...

The team focused on the mechanical properties of proteins for the analysis and mapping between primary amino acid sequences and secondary protein structures. The models considered conditioning ...

Interestingly, most amino acids come in at least two forms, whose structures represent mirror ... It was found that the abundance of secondary minerals (formed after aqueous alteration), including ...

These elements form the same amino acid structure. In the center is a carbon atom. It’s attached to a hydrogen atom, a basic amino group (a group of elements), a carboxylic acid group (another ...

The question of how life could have emerged is one of the most long-standing mysteries in science. In a new study, the laboratory of LMU Professor Dieter Braun has uncovered an unexpected form of ...

three are considered branched-chain amino acids (BCAAs): leucine, isoleucine, and valine. “Branched-chain” refers to the chemical structure of BCAAs, which are found in protein-rich foods such ...
