BIOL 2020 Lecture Notes - Carboxylic Acid, Amine, Chief Operating Officer
Document Summary
Amino acids-definately memorize each amino acid, the abbrev, the letter, And how it looks, what makes it different as well! 3. 1 proteins are built from a repertoire of 20 amino acids. -amino acid consists of an -carbon, linked to an amino group, a carboxylic acid group, a hydrogen atom and a side chain (r group) Amino acids are chiral meaning they exist in 2 mirror image forms called l isomer and d isomer. Only l amino acids are made of proteins. Free amino acids exist as dipolar ions/zwitterions, the amino group is protonated, and the carboxyl group is deprotonated (coo-) In acidic: amino group is protonated, and carboxyl group is not dissociated. Ph rises, carboxylic acid gives up a proton, and its dipolar until ph of 9, where amino acid loses a proton. 3. 2 amino acids contain a wide array of functional groups.
