Document Summary

Classses of organic molecules: carbohydrates, lipids, protet5ins, nucleic acids. Be able to look at structure and tell what molecule it is. Carbohydrates: name means carbon in water, compounds with a ratio of, 1 carbon, 2 hydrogens and 1 oxygen, 1 carbon molecule and 1 water molecule. This molecule can be: carbohydrate and fatty acids (lipids, you find an organic molecule that contains phosphorus. This molecule can be a: lipid, nucleic acid. Proteins: polymers of amino acids, unbranched chains (linear molecules- beginning and end) Amino acids: building blocks of protein, contain central c to which is attached, an amino group, a carboxyl group, a hydrogen, something else {r} Amino acid polymer: amino acids are joined together to form un-branched chains, the bond joining the amino acids is a peptide bond. Protein structure: primary 1 degree (primary structure, a description of the covalent bonds and the sequence of amino acids in a protein, secondary structure, repeated spatial patterns, two forms.
