Chemistry Stack Exchange is a question and answer site for scientists, academics, teachers, and students in the field of chemistry. It only takes a minute to sign up. I have the settings in ACS Document style. Is there anyway to make the format render my "backwards" type? ChemDraw is a piece of software that attempts to be as intelligent as possible. In many cases, that is truly helpful, in others it can be annoying. When labelling an atom in text mode, ChemDraw will automagically assume a label from left to right i.
If you then manually rotate the entire molecule within ChemDraw, you will notice the OH flipping into an HO as soon as it graphically makes sense to do so.
Note that if you just hover over the atom in lasso mode or bond adding mode and then hit o lowercase! Hitting o again will remove the additional hydrogen this holds true for all chemical elements that are attached to single letters regardless whether the atom is attached to a lowercase letter i.
The preferred way would be to add an abbreviation to ChemDraw. Sign up to join this community. The best answers are voted up and rise to the top. Home Questions Tags Users Unanswered.

However, as it is working with my version and you have a newer one, I suppose it should work with yours, too.
You can find me in Chemistry Chat to talk about it. Have you tried entering "OH" instead?

The CDX file format offers several properties of brackets that allow users to specify the context of those repeating units, as well as their orientation.
There are two main representations for polymers, structure-based and source-based. There is little benefit of one form over the other, and both have been widely used. Structure-based representations enclose only a portion of a structure within brackets. One or more bonds will cross each of the brackets that enclose the structure.
With such a representation, those crossing bonds "match up", making the polymer structure more explicit. Poly vinyl chloridestructure-based representation. For more information about these types, please consult the references at bottom.
In a source-based representation, an entire discrete chemical substance is enclosed within the brackets. The mode of polymerization might be obvious from context for example, the breaking of a double bond to form a diradicalor it might be unknown. Source-based representations are particularly useful when describing processes where the starting materials are known, but the exact structure of the reaction product is not.
Poly vinyl chloridesource-based representation. Copolymers, as above, represent substances with more than one repeating unit. It could be used, for example, to indicate the products of a reaction. Multiple Group brackets may enclose entire structures, or may enclose a portion of the structures only. Although this property is written to both Graphic objects and to Bracketed Groupsas of ChemDraw 7.
This is an enumerated property. Brackets enclose a source-based monomeric unit that is known not to self-polymerize. Brackets enclose one of several repeating units that co-polymerize in an alternating fashion. Brackets enclose one of several repeating units that co-polymerize in a random fashion. Brackets enclose one of several repeating units that co-polymerize in a block fashion. Brackets enclose a collection of substances that comprise an ordered mixture also called a formulation.Vitamin B 12a complex water-soluble organic compound that is essential to a number of microorganisms and animals, including humans.
Vitamin B 12 aids in the development of red blood cells in higher animals. The vitamin, which is unique in that it contains a metallic ion, cobalthas a complex chemical structure as shown:. Vitamin B 12 occurs in several forms, called cobalamins; cyanocobalamin is the principal one used in vitamin supplements and pharmaceuticals. Vitamin B 12 is involved in cellular metabolism in two active coenzyme forms—methylcobalamin and 5-deoxyadenosylcobalamin. Vitamin B 12 cooperates with folic acid folate in the synthesis of deoxyribonucleic acid DNA.
A deficiency of either compound leads to disordered production of DNA and, hence, to the impaired production of red blood cells. Vitamin B 12 also has a separate biochemical role, unrelated to folic acid, in the synthesis of fatty acid s in the myelin sheath that surrounds nerve cells. See table of the vitamins. Vitamin B 12 is synthesized by microorganisms that occur in the rumen the first stomach chamber of cows and sheep.
From the rumen it is transferred to the muscle and other tissues, which other animals and humans eat. Good dietary sources of vitamin B 12 are eggs, meat, and dairy products.
Several kinds of bacteria unable to make the substance require minute amounts for growth. In humans a lack of the vitamin results in defective formation of the papillae small projections of the tongue, giving an appearance of abnormal smoothness. A deficiency of vitamin B 12 often causes defective function of the intestine, resulting in indigestion and sometimes constipation or diarrhea.
A very serious effect is degeneration of certain motor and sensory tracts of the spinal cord; if the degeneration continues for some time, treatment with vitamin B 12 may not correct it. Initial numbness and tingling of fingers or toes may, without treatment, progress to instability of gait or paralysis. Because vitamin B 12 is found in animal but not vegetable foods, strict vegetarians vegans who do not eat dairy products, meats, fish, eggs, or vitamin B 12 -fortified foods may develop a deficiency if they do not receive supplements of the vitamin.
Deficiency may also result from competition for vitamin B 12 by the broad tapeworm or by intestinal bacteria growing in cul-de-sacs or above partial obstructions in the digestive tract.
Additional nutritional deficiencies, such as those of folic acid or ironare likely to develop in such cases, as in primary intestinal diseases such as celiac diseasetropical sprueor regional enteritisall of which affect the absorptive capacity of the small bowel. Pernicious anemiaa disease characterized by the impaired production of red blood cells, is caused by the lack of intrinsic factora substance that is normally produced by the stomach and binds with vitamin B 12allowing it to be absorbed and used by the body; treatment involves the administration of intramuscular injections of the vitamin.
