Erythritol

1,2,3,4-Butanetetrol,(2R,3R)-rel-

C4H10O4 (122.0579)


Erythritol is a sugar alcohol (or polyol), used as a food additive and sugar substitute. It is naturally occurring and is made from corn using enzymes and fermentation. Its formula is C4H10O4, or HO(CH2)(CHOH)2(CH2)OH; specifically, one particular stereoisomer with that formula. Erythritol is 60–70\\\\\% as sweet as sucrose (table sugar), yet it is almost noncaloric and does not affect blood sugar or cause tooth decay. Erythritol occurs widely in nature and has been found to occur naturally in several foods including wine, sake, beer, watermelon, pear, grape, and soy sauce. Evidence indicates that erythritol also exists endogenously in the tissues and body fluids of humans and animals. Erythritol is absorbed from the proximal intestine by passive diffusion in a manner similar to that of many low molecular weight organic molecules which do not have associated active transport systems. The rate of absorption is related to their molecular size. It passes through the intestinal membranes at a faster rate than larger molecules such as mannitol or glucose. In diabetics, erythritol has also been shown to be rapidly absorbed and excreted unchanged in the urine. Following absorption, ingested erythritol is rapidly distributed throughout the body and has been reported to occur in hepatocytes, pancreatic cells, and vascular smooth muscle cells. Erythritol also has been reported to cross the human placenta and to pass slowly from the plasma into the brain and cerebrospinal fluid (PMID:9862657). Erythritol is found to be associated with ribose-5-phosphate isomerase deficiency, which is an inborn error of metabolism. Bulk sweetener with good taste props. Not metabolised, excreted unchanged in urine. Less sweet than sucrose. Use not yet permitted in most countries (1997). GRAS status for use as a sweetener, thickener, stabiliser, humectant, etc. in food meso-Erythritol is a sugar alcohol that occurs naturally in a variety of foods (e.g., pear, watermelon), is 60-80\\% as sweet as sucrose, and is an approved low-calorie sweetener food additive[1]. meso-Erythritol is a sugar alcohol that occurs naturally in a variety of foods (e.g., pear, watermelon), is 60-80\% as sweet as sucrose, and is an approved low-calorie sweetener food additive[1].

   

L-Erythrulose

(3S)-1,3,4-Trihydroxybutan-2-one

C4H8O4 (120.0423)


L-Erythrulose is an extremely reactive ketose, which rapidly glycates and crosslinks proteins, and therefore may mediate the(L-ascorbate) AsA-dependent modification of protein (ascorbylation) seen in vitro, and also proposed to occur in vivo in human lens during diabetic and age-onset cataract formation.(PMID: 10727845) [HMDB] L-Erythrulose is an extremely reactive ketose, which rapidly glycates and crosslinks proteins, and therefore may mediate the(L-ascorbate) AsA-dependent modification of protein (ascorbylation) seen in vitro, and also proposed to occur in vivo in human lens during diabetic and age-onset cataract formation.(PMID: 10727845).
