BIOL 2020 Chapter Notes - Chapter 1: Central Dogma Of Molecular Biology, Bond Energy, Deoxyribose
Document Summary
Goal of biochemistry: to know what it means to be alive at the molecular level and to understand how molecular manipulations affect the life the organism leads. Organisms are remarkably uniform at the molecular level. 1. 1 living systems require a limited number of atoms and molecules. O, h, and c make up 98% of atoms in an organism. Matrix of life-refers to o and h-> h2o. C-c bonds (stability and bond energy, also can dissolve in h2o and can exist as a gas) are stronger than si-si bonds. 1. 2 there are four major classes of biomolecules. Proteins: most versatile, 20 amino acids, 3d structure, serve as signal molecules and receptors, are catalysts specifically made of proteins are called: enzymes. Nucleic acid: function: to store and transfer info. Nucleotide is made up of: 5-c sugar, deoxyribose or ribose, attached to a base and one phophoryl group. Dna: parts list, (acgt), mostly double stranded, liked by phosphodiester bonds.
