Yes, mannose and galactose diastereoisomers consider only d-sugars because mannose is bundled as the nourishing supplement "d-mannose", is a sugar monomer of the aldohexose series of carbohydrates. Mannose is a C-2 epimer of glucose. Mannose is significant in human absorption, particularly in the glycosylation of certain proteins. Numerous congenital conditions of glycosylation are related with transformations in enzymes involved in mannose absorption.
<span>well there are many health effects you can talk about... vomiting, diarrhea, various other forms of sickness often prokaryotes or bacteria will cause the contamination... this is
normally taken care of in places that have a water treatment facility to
filter out all that nasty stuff they can spread in various ways from one person to the next but one of
the most common is the fecal-oral route, meaning that the disease can be
spread is someone ingests something that has somehow come into contact
with the feces of a person who has the disease </span>
second challenge to life on land was the distribution of water and other materials to each cell. In aquatic forms, transport occurs directly from the surrounding environment. On land, however, plants must get water and other materials from the soil.<span>Body support
</span><span>As plants evolved from aquatic to terrestrial environments, several obstacles stood in the way. One obstacle was structural support. In water, organisms are buoyant and the effects of gravity are minimal. Even among larger forms, like kelps, structures with gas-filled vesicles allow them to float. On land, however, if a plant is to grow tall, it needs to withstand the forces of gravity.
</span><span>A third challenge during the transition to land involved bringing sex cells together. In water, sperm are able to swim directly to eggs. On land, this can only happen in moist environments.
