Diaminoácido

Diaminoácido is a term that refers to amino acids containing two amino groups. In organic chemistry, amino acids are typically characterized by a central carbon atom, an amino group, a carboxyl group, and a side chain. However, diaminoácidos possess an additional amino group, which can be located in the side chain or, in some less common cases, as a second functional group attached to the main carbon backbone.

The presence of an extra amino group significantly alters the chemical properties of these molecules compared to standard amino acids. The additional basic amino group increases their overall basicity and can influence their solubility and reactivity. In biological contexts, diaminoácidos play crucial roles. Some are essential building blocks of proteins, contributing unique properties to their structure and function. Others serve as precursors for important biomolecules, such as neurotransmitters or pigments. For example, lysine and arginine are common diaminoácidos found in proteins, and their positive charge at physiological pH is vital for various cellular processes. Diaminoácidos are important in biochemistry and organic synthesis.
