Document Summary

Chapter 5: the structure and function of macromolecules. The four major classes of biologically important organic molecules are: carbohydrates, lipids, proteins, or polypeptides (and related compounds), and nucleic acids (and related compounds) Note that they are all isomers of each other (i. e. they have the chemical formula c6h12o6). Glucose and galactose are structural isomers of fructose, while glucose and galactose are diastereomers (a type of stereoisomer). pentose and hexose sugars actually form ring structures in solution this often creates diastereomersexample: -glucose and. Vi. nucleic acids transmit hereditary information by determining what proteins a cell makes two classes of nucleic acids found in cells: deoxyribonucleic acid (dna) A. and ribonucleic acid (rna: dna carries the genetic information cells use to make proteins, rna functions in protein synthesis according to mechanisms we will discuss later in the semester. Dna typically contains the purines adenine(a) and guanine(g), and the pyrimidines cytosine(c) and thymine (t)
