  • Further remarkable applications of ß-amino acids are the use as protease inhibitors, 11 precursors for antibiotics 12 and building blocks in cryptophycins. (sigmaaldrich.com)
  • Consequently, amino acids are also precursors of glucose , fatty acids, and ketone bodies and are therefore metabolic fuels. (conservapedia.com)
  • Amino acids are also important in many other biological molecules, such as forming parts of coenzymes, as in S-adenosylmethionine, or as precursors for the biosynthesis of molecules such as heme. (medicalxpress.com)
