An L isomer of monosaccharide formed in the human body is

Monosaccharides are those sugars that cannot be hydrolyzed into simpler carbohydrates. They may be classified as trioses, tetroses, pentoses, hexoses, or heptoses, depending upon the number of carbon atoms (3-7), and as aldoses or ketoses, depending on whether they have an aldehyde or ketone group. d and l isomerism: The designation of a sugar isomer as the d form or its mirror image as the l form is determined by its spatial relationship to the parent compound of the carbohydrates, the three-carbon sugar glycerose (glyceraldehyde).Pentoses of Physiological ImpoanceSugarBiochemical and ClinicalImpoanced-RiboseStructural component ofnucleic acids andcoenzymes, includingATP, NAD(P), and flavincoenzymesd-RibuloseIntermediate in the pentosephosphate pathwayd-ArabinoseConstituent of glycoproteinsd-XyloseConstituent ofglycoproteinsl-XyluloseExcreted in the urine inessential pentosuriaRef: Harper&;s Biochemistry; 30th edition; Chapter 15; Carbohydrates of Physiological Significance
