WebAboutTranscript. Amino acids are the building blocks of proteins. They contain an amino group, carboxylic acid group, alpha carbon, and side chain. Most amino acids have a chiral carbon, which allows them to rotate polarized light. Amino acids can have either an L- or D- configuration, but only the L- form is found in the human body. WebThe name of the first molecule is (R)-4-methylcyclohexene. The double bond gets priority in the naming, and the numbers must include both alkene carbon atoms. So C-1 is at the bottom, C-2 is at the 4-o'clock position, and the methyl group is on C-4. The name of the second molecule is (S)-3-bromo-3-chloro-2-methylpentane. shrouds gaming chair https://shift-ltd.com
