An Acid is an organic compound with acidic properties, mostly produced in the plants. Some organic acids are with carboxyl group -COOH, group -SO2OH. Other groups can also confer acidity, usually weakly: the thiol group -SH, the enol group, and the phenol group. Organice acids are commonly used for acidulant, antioxidant, flavoring agent, and some possess antibacterial activities. An aldehyde is an organic compound containing a functional group with the structure -CHO, consisting of a carbonyl center (a carbon double-bonded to oxygen) with the carbon atom also bonded to hydrogen and to an R group, which is any generic alkyl or side chain. Many aldehydes are found in essential oils and often contribute to their favorable odors, e.g. cinnamaldehyde, cilantro, and vanillin. Possibly because of the high reactivity of the formyl group, aldehydes are not common in several of the natural building blocks: amino acids, nucleic acids, lipids. Most sugars, however, are derivatives of aldehydes. These aldoses exist as hemiacetals, a sort of masked form of the parent aldehyde. For example, in aqueous solution only a tiny fraction of glucose exists as the aldehyde.

Taurine

Taurine is an organic acid widely distributed in animal tissues.Target: OthersTaurine is a major constituent of bile and can be found in the large intestine and accounts for approximately 0.1% of total human body weight [1]. Taurine is present in high concentration in algae and in the animals including insects and arthropods, but is generally absent or present in traces in the bacterial and plant kingdoms [2]. In cardiac tissue alone, taurine levels of 20 mM or higher may be found. Taurine availability protects against cholestasis induced by monohydroxy bile acids remains confined to guinea pigs [3]. Oral supplementation of taurine results in increased plasma taurine concentrations and is associated with normalization of left ventricular function in both groups of cats. Myocardial concentrations of taurine are directly related to plasma concentrations and low plasma concentrations are found to be associated with myocardial failure in cats, proposing a direct link occurs between decreased taurine concentration in the myocardium and decreased myocardial mechanical function [4].
