Chemical formula. C 5 H 9 N O 3: Molar mass: ... (2S,4R)-4-Hydroxyproline, or L-hydroxyproline (C 5 H 9 O 3 N), is an amino acid, abbreviated as Hyp or O, e.g., in ...
The formula for this acid is generally written H 3 PO 2, but a more descriptive presentation is HOP(O)H 2, which highlights its monoprotic character. Salts derived from this acid are called hypophosphites. [3] HOP(O)H 2 exists in equilibrium with the minor tautomer HP(OH) 2. Sometimes the minor tautomer is called hypophosphorous acid and the ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
A chemical formula is a way of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus (+) and minus (−) signs.

Aliphatic compounds can be saturated, joined by single bonds (), or unsaturated, with double bonds or triple bonds ().If other elements (heteroatoms) are bound to the carbon chain, the most common being oxygen, nitrogen, sulfur, and chlorine, it is no longer a hydrocarbon, and therefore no longer an aliphatic compound.
Hydroxyapatite is widely used within dentistry and oral and maxillofacial surgery, due to its chemical similarity to hard tissue. [34] In the future, there are possibilities for using nano-hydroxyapatite for tissue engineering and repair. The main and most advantageous feature of nano-hydroxyapatite is its biocompatibility. [35]
