Biochemistry, 4th Edition P1

Biochemistry, 4th Edition P1. Continuing Garrett and Grisham's innovative conceptual and organizing framework, "Essential Questions," BIOCHEMISTRY guides students through course concepts in a way that reveals the beauty and usefulness of biochemistry in the everyday world. Streamlined for increased clarity and readability, this edition also includes new photos and illustrations that show the subject matter consistently throughout the text. New end-of-chapter problems, MCAT practice questions, and the unparalleled text/media integration with the power of CengageNOW round out this exceptional package, giving you the tools you need to both master course concepts and develop critical problem-solving skills you can draw upon. | Physical Constants Name Symbol SI Units cgs Units Avogadro s number N 6.022137 X 1023 mol 6.022137 X 1023 mol Boltzmann constant k 1.38066 X 10 23J K 1.38066 X 10 16 erg K Curie Ci 3.7 X 1010 d s 3.7 X 1010 d s Electron charge e 1.602177 X 10 19 coulombf 4.80321 X 10 10 esu Faraday constant 9 96485 J V mol 9.6485 X 1011 erg V mol Gas constant R 8.31451J K mol 8.31451 X 107 erg K mol Gravity acceleration g 9.80665 m s2 980.665 cm s2 Light speed vacuum c 2.99792 X 108 m s 2.99792 X 1010 cm s Planck s constant h 6.626075 X 10 34 J s 6.626075 X 10 27 erg s Other values of R 1.9872 cal K mol 0.082 liter atm K mol. f1 coulomb 1 J V.
