BIOLCHEM 415 1st Edition Lecture 1Outline of Current Lecture I. Four Major Classes of BiomoleculesA. Proteins, Lipids, Carbohydrates, Nucleic AcidII. Central Dogma describes transfer of information in the bodyCurrent LectureProteins- amino acid polymers- linked by peptide bonds- fold into 3D shapes- shape affects function- functions include:- signals- receptors- catalysts- building blocks- molecular motorsCarbohydrates- fuel source- e.g. glucose- energy storage- e.g. glycogen- signaling molecules These notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- when linked with proteinsNucleic Acids- formed from nucleotides- store and transmit genetic info- composed of:- base- sugar- phosphate- functions include- enzyme, structural, signaling- energy currency (power cell)- DNA- double stranded with antiparallel strands- helix- composed of four bases- adenine, guanine, cytosine, thymine- sugar = 2’ deoxyribose- RNA- single stranded- can be double- sugar: ribose- composed of four bases:- adenine, guanine, cytosine, uracil- the sequence of the nucleotides is extremely importantCentral DogmaReplication- catalyzed by DNA polymerase- new polymers of DNA createdTranscription- catalyzed by RNA polymerase- a complimentary RNA created based on the existing DNA strand- each cell expresses only a certain type of RNATranslation- RNA transformed to protein- powered by
