ANCIENT MARINER. "We need sugars in our diet, but if we were to eat the mirror image of these sugars, molecules that contain the same atoms but only arranged in the left-handed form, then we would starve, as our bodies can only metabolize the right-handed form." This is the basis for some calorie-free artificial sweeteners. https://lnkd.in/eqzkdcz View in LinkedIn

"ARTHUR C. CLARKE writes about a molecular mirror-image human being starving to death because his body cannot process normal sugars." Would they also be immune to microbial infections, plagues and diseases for the same reason? The Reversed Man or The Technical Error). https://lnkd.in/e2N3umX View in LinkedIn

WONDERLAND. "Perhaps Looking-glass milk isn't good to drink," Alice said to her cat" after being inverted by the mirror in the wardrobe. A prescient allusion despite the fact relatively little was known about the chemistry of enantiomeric drugs or foods at that time. (Through the Looking Glass, Lewis Caroll). https://lnkd.in/eYuN5mG View in LinkedIn

UNTREATED MILK consists mostly of L-amino acids, including L-aspartic acid, L-glutamic acid and L-alanine, with the L-form 5-10X higher than the D-form. Microbial infection causes an Alice in Wonderland racemisation to a relatively higher percentage of the D-form, or Looking-Glass Mirror milk. The same occurs on pasteurization or fermentation. https://lnkd.in/eJHCuGP View in LinkedIn

RACEMIZED MILK. "Payan studied the changes brought about during milk treatment by measuring the concentration of D-aspartic acid. Raw milk contained the smallest amount of D-aspartic acid (1.48%)." https://lnkd.in/epgx4-P View in LinkedIn

RACEMIZED MILK. "D-aspartic acid...increased in direct proportion to the number of treatments (acidophilus milk: 2.05%; low fat milk powder: 2.15%; kefir: 2.44%; evaporated milk: 2.49%; yoghurt: 3.12%; milk-based baby formula: 4.95%)." https://lnkd.in/epgx4-P View in LinkedIn

FOODS WITH D AMINO ACIDS. Yoghurt, cheese, roasted coffee, milk powder all contain substantial amounts of D-amino acids. https://lnkd.in/eNSAN8h View in LinkedIn

BACTERIAL ORIGIN. "The study verifies that the D-amino acid content of commercially available milk might be attributable to the first jets of milk produced or to milk originating from cows with subclinical mastitis." https://lnkd.in/eNSAN8h View in LinkedIn

CONVERTIBILITY. "Before an animal can utilize an ingested D-amino acid it must convert it to the L form." https://lnkd.in/ejQc5Sk View in LinkedIn

CONVERTIBILITY. D-Methionine, D-isoleucine, D-phenylalanine, are readily converted and is completely bioavailable in animals, while D-lysine, D-cysteine, D-histidine, D-leucine, D-isoleucine, D-threonine, and D-valine do not convert and is not used by animals. Others vary considerably by species. https://lnkd.in/ejQc5Sk View in LinkedIn
