Ch. 1 -Biochemistry is the scientific discipline that seeks to explain life at the molecular level. -Only a small subset of the known elements occur in biomolecules. The most abundant of these are C,N, O, and H -The chemical reactivity of biomolecules is limited relative to the reactivity of all organic compounds. Most of the cell’s small molecules can be divided into four groups. Although each group contains many members, they are united under a single structural or functional definition. 1) Amino Acids -Contain an amino group (-NH2) and a carboxylic acid group (-COOH) 2) Carbohydrates (monosaccharides) 3) Nucleotides -Components include a five-carbon sugar, nitrogen containing ring, and one or more phosphate groups 4) Lipids -Poorly soluble in water because of their hydrocarbon-like nature. There are three major kinds of biological polymers -Universal feature of nature: a few kinds of building blocks can be combined in different ways to produce a wide variety of larger structures -Amino acids, monosaccharides, and nucleotides each form polymeric structures with widely varying
