Biological Molecules -Biological molecules consist primarily of carbon, oxygen, hydrogen, and nitrogen. -These elements share valence electrons to form bonds so that they have electron configurations like those of a noble gas element. -Since there are so combinations of carbon, nitrogen, oxygen, and hydrogen, it is possible to form many compounds from just these few elements.
2
Biological Molecules -Biological molecules, such as proteins, nucleic acids, and starch, are made up of various combinations of a small number of subunits. Examples: carbohydrates (bread, pasta) – sugars proteins – amino acids DNA – nucleotides
3
Biological Molecules -Proteins are long chains (polymer) made up of many small subunits called amino acids. Bonds between amino acids are called peptide bond, is identical for any pair of amino acids. -Different proteins have different amino acids and are ordered in different ways which determines their function.
4
Biological Molecules -DNA determines how protein molecules are made and biotechnology is a career field that studies DNA, amino acid sequences, and the shapes and functions of proteins.
