A crystalline tetrahydroxy alcohol, HOCH2(CHOH)2CH2OH, formed by the reduction of threose.
1935Jrnl. Amer. Chem. Soc. LVII. 2262/2 Consistency also strongly urges limiting the term ‘erythritol’ to the natural inactive alcohol.., and using the terms ‘d-threitol’ (rotating + 4·33° in water) and ‘l-threitol’ (rotating - 4·4° in water) for the active tetritols derived, respectively, from the two threoses. 1948Biochem. Jrnl. XLII. 330/1 The new product is apparently identical with the substance synthesized by Maquenne from natural xylose and described under the name of ‘l-erythritol’. The name was later changed to ‘d-erythritol’ in accordance with the Rosanoff convention for sugars, but recently it has been thought advisable to change the name to d-threitol to relate it more closely to the tetrose threose. 1960Ibid. LXXVII. 272/1 Preparations are given for l-threitol and mesoerythritol. 1975Nature 11 Dec. 519/1 In adult tenebrionid beetles..an unusual combination of two polyhydric alcohols, sorbitol and threitol, is associated with the ability to tolerate prolonged freezing to at least - 50°C. The occurrence of threitol is of particular interest, since this compound has not previously been found in nature. |
