Unformatted text preview: ATP . The amino group makes the molecule a base whereas the _ carboxyl group makes the molecule an acid. The _ carbonyl group formula C=O is called an aldehyde if on the end of the molecule. The _ sulfhydryl group on the amino acid cysteine is often used to form cross-links within or between proteins. There are many examples of proteins having their function change by_ phosphorylation or dephosphorylation . Make a chart of the seven main functional groups, giving the name, chemical formula, and the name of a molecule in which the group is found. 1. Hydroxyl-OH alcohols 2. Carbonyl C=O aldehydes and ketones, sugars 3. Carboxyl-COOH organic acids, amino acids 4. Amino-NH 2 amines, amino acids, 5. Sulfhydryl-SH thiols, cysteine 6. Phosphate-PO 4 ATP, organic phosphates 7. Methyl-CH 3 cytidine, testosterone...
