Arginine (Arg, R): Arginine has a guanidinium group as its R group, a complex nitrogen-containing group that is positively charged at physiological pH. Arginine is highly basic and participates in ...

Plants produce all amino acids essential for human life. This commonly occurs in specialised cell organelles, so-called plastids. A research team headed by Heinrich Heine University Düsseldorf (HHU) ...

Although the myriad proteins found in all life are largely built from a set of 20 amino acids, many other amino acids exist in nature, and it remains a curiosity as to why some were ultimately ...

The first four components are constant across all amino acids, while the R-group varies, giving each amino acid its unique properties. The alpha carbon is chiral (except for glycine), meaning it is ...

Leucine and isoleucine are among the 20 amino acids found naturally in the human body. They are very similar in structure but have small differences which change their physiological properties. Both ...

Figure 1: Changes in clinical, MRI and immunological parameters during therapy with CGP77116. None of the MRI parameters changed substantially. Compared with baseline (cumulative 48 patient-months), ...

UCLA researchers have created a code to translate amino acid sequences into music, to inform and entertain non-scientists and children. If you're enjoying this article, consider supporting our ...
