homovanillic acid has been researched along with Apnea in 3 studies
Homovanillic Acid: A 3-O-methyl ETHER of (3,4-dihydroxyphenyl)acetic acid.
homovanillate : A hydroxy monocarboxylic acid anion which is obtained by deprotonation of the carboxy group of homovanillic acid.
homovanillic acid : A monocarboxylic acid that is the 3-O-methyl ether of (3,4-dihydroxyphenyl)acetic acid. It is a catecholamine metabolite.
Apnea: A transient absence of spontaneous respiration.
