Витамин C ускорява инвертирането - мисля, че няма нужда да се доказва.
Като започнем от меда и стигнем до задника на пчелата на 1000 места има нужда от него.
Просто изследванията са малко, често са комбинирани или изобщо не се обръща сериозно внимание.
Витамин C много лесно влиза в реакция с други вещества и точно това е причитана да се ползва за антиоксидант, като живота му е много кратък и лесно се разрушава.
Това, че го има в малки количества значи ли, че не е нужен и по тази логика като нямаш пари в портфейла, то значи пари не ти трябват?!?!?!

It is, however, possible to trick bees to take the substitute when necessary by integrating a small amount of Vitamin C into the mixture.

Furthermore, prepupae reared by bees constrained to a vitamin C-free diet contained similar vitamin C levels than did those reared by bees fed vitamin C-enhanced diets. Therefore, honey bees (or their symbiotic microorganisms) are assumed to be able to synthesize vitamin C.

Vitamin C will improve the bee’s blood building processes and their immune system. The added acid is also of value to the digestive system.

Ascorbic acid (vitamin C) also seems essential for brood rearing.

The results indicated that supplementing the level of vitamin C to spring nutrition (1:1suger syrup) to the colonies, increase the brood area, colony population and the workers body weight and protein.

Pollen proved to be a rich but variable source of Vitamin C depending on the date of collection and floral source. There was, however, no relationship between the vitamin C level in the pollen collected and the rate of brood rearing. There were highly significant differences in the vitamin C levels in pollen depending on the date of collection. In the study using caged bees, significantly more brood was reared by bees fed either the diet supplemented with 500 pg/g or the control than by bees offered diets containing either 1 000 or 2 000 pg/g L-ascorbic acid. This study also demonstrated for the first time that bees are able to produce this vitamin since prepupae from colonies fed the diets without vitamin C had equivalent levels of ascorbic acid to those fed the enriched diets. Previous studies on the levels of vitamin C in pollen may be underestimated since the pollen samples were often not « fresh » and only ascorbic acid was determined not both ascorbic acid and dehydroascorbic acid.
In general, the vitamin C exists in its ascorbic acid from with little dehydroascorbic present.Although fresh pollen possesses high levels of vitamin C, little is retained in the body tissue of prepupae and bees apparently are able to produce this vitamin since prepupae reared by bees fed a vitamin C-free pollen substitute contained levels similar to the levels in prepupae reared on vitamin C supplemented diets.

In addition to these vitamins, ascorbic acid ( vitamin C) also seems essential for brood rearing.

Very little information, however, has been available regarding the effect of vitamin C on micro-organisms, and we undertook this work in 1936, as it seemed to us that the study of the effect of vitamin C on such simple organisms might throw some light on the mechanism of the action of vitamin C.
