Singh C, Rai RK, Aussenac F, Sinha N.
PMID: 26276492
J Phys Chem Lett. 2014 Nov 20;5(22):4044-8. doi: 10.1021/jz502081j. Epub 2014 Nov 07.

Aromatic amino acids (AAAs) have rare presence (∼1.4% abundance of Phe) inside of collagen protein, which is the most abundant animal protein playing a functional role in skin, bone, and connective tissues. The role of AAAs is very crucial...
