During this time, McKesson hired graphic artist Bill Young to develop a "Harvey Wallbanger" character to market the drink, which tends to negate the attribution of the drink and its name to bartender Donatao "Duke" Antone. Various authors have speculated that Bednar may have commissioned recipe for the drink itself from Antone, or developed it internally. The drink is composed of vodka, orange juice and Galliano liqueur, then a
Orange juice d-galacturonic acid unit along with blocks of L-rhamnose regions that have side chains of arabinose, galactose, and xylose. Pectin methyl-esterase is the enzyme responsible for hydrolyzing carboxymethyl esters and liberating free carboxyl groups and methyl alcohols. The free carboxyl groups interact with cations to form insoluble pectic acid divalent metal ion complexes. These metal ion complexes precipitate in the juice and carry all the colloids in orange juice with it. The enzyme would flocculate the cloud and clarify the orange juice. Thus, in order to keep the orange juice cloud intact, it is vital to inactivate pectinesterase. Pectinesterase is inactivated
