The only hydrophobic group below is the methyl (CH, One example of a strongly hydrophilic group is the carboxyl group (COOH), which can act as an acid and lose a proton to form a negatively-charged carboxylate ion (COO, In the table above, the letter R is used to represent the rest of the molecule that a functional group is attached to. The carbonyl group is a super function because many common functional groups are based on a carbonyl, including: aldehydes, ketones, carboxylic acids, esters, amides, acyl (acid) chlorides, acid anhydrides : Ester. Among the hydrophilic functional groups is the carboxyl group found in amino acids, some amino acid side chains, and the fatty acid heads that form triglycerides and phospholipids. /r/MCAT is a place for MCAT practice, questions, discussion, advice, social networking, news, study tips and more.

Rank the compounds in order of increasing polarity (1 = least polar, 3 most polar). How do you determine if a group is polar? That first ranking I gave was from URanus and I'm not sure why they have it like that. Because the chemical behavior of many reactive atoms or groups of atoms is well characterized, the presence and position of specific functional groupson an organic molecule can be used to predict the chemical behavior of that biomolecule.
