The most significant experimental results on the putative synthesis of various carbohydrates and their derivates from simple substrates in plausible prebiotic conditions are summarized and discussed. The synthesis of monosaccharides from formaldehyde and lower carbohydrates (glycolaldehyde, glyceraldehyde, dihydroxyacetone) can be catalyzed by different compounds such as lead, phosphate and borate ions and several natural minerals. Lower carbohydrates can be directly formed in aqueous formaldehyde solutions under the action ofUV-irradiation. The possible role of carbohydrates and their derivates in the chemical evolution and development of presumable abiogenic metabolism is illustrated as well. [ABSTRACT FROM AUTHOR] |
