【pharmacology】：rhamnose is a naturally-occurring deoxy sugar. it can be classified either as a methyl-pentose or a 6-deoxy-hexose. rhamnose occurs in nature in its l-form as l-rhamnose (6-deoxy-l-mannose). this is unusual since most of the naturally-occurring sugars are in d-form. exceptions are the methyl pentoses l-fucose and l-rhamnose and the pentose l-arabinose.
l-rhamnose can be isolated from buckthorn (rhamnus) and poison sumac. it is also found as a glycoside in a variety of other plants. rhamnose is a component of the outer cell membrane of acid-fast bacteria in the mycobacterium genus, which includes the organsism that causes tuberculosis
