the side chain for valine is classified as a
Valine Valine (symbol Val or V[3]) is an α-amino acid that is used in the biosynthesis of proteins. It contains an α-amino group (which is in the protonated −NH3+ form under biological conditions), an α-carboxylic acid group (which is in the deprotonated −COO− form under biological conditions), and a side chain isopropyl group, making it a non-polar aliphatic amino acid. It is essential in humans, meaning the body cannot synthesize it: it must be obtained from the diet. Human dietary sources are foods that contain protein, such as meats, dairy products, soy products, beans and legumes. In the genetic code it is encoded by all codons starting with GU, namely GUU, GUC, GUA, and GUG.
Valinor Valinor (Land of the Valar) is a fictional location in J. R. R. Tolkien's legendarium, the realm of the Valar in Aman. It was also known as the Undying Lands, along with Tol Eressëa and the outliers of Aman. This latter name is somewhat misleading; the land itself, while blessed, did not cause mortals to live forever.[1] However, only immortal beings were generally allowed to reside there. Exceptionally, the surviving bearers of the One Ring were allowed to dwell there for a time--Bilbo and Frodo Baggins and Sam Gamgee--and perhaps[dubious – discuss] Gimli son of Glóin who, it is said, accompanied his friend Legolas to Valinor.[2][3]
