polar
Yes.
Yes it is. It is composed of a non-polar carbon chain with a polar COOH head.
COOH-
They are soluble in water as the functional group (-OH for alkanols and -COOH for alkanoic acids) make each of the molecules polar and can therefore form a bond with water.
An organic acid with a COOH group is called a carboxylic acid.
because
Yes it is. It is composed of a non-polar carbon chain with a polar COOH head.
No because all amino acids are polar. RCH(NH2)COOH as the COOH part disassociates and polar compounds can not passively pass through a cell membrane. There are carrier proteins that negotiate that passage.
H2CO is a polar molecule. It contains a carbonyl group, which is a C=O bond. O is an extremely electronegative atom, compared to carbon.
COOH-
Because fatty avid has 'COOH' at one terminal which is polar part and attracted by water.
"cooh" is not an element and therefore does not have an atomic number.
COOH, or CO2H, is a 'carboxyl'.
The carboxyl group is writed -COOH.
They are soluble in water as the functional group (-OH for alkanols and -COOH for alkanoic acids) make each of the molecules polar and can therefore form a bond with water.
To be soluble a solution must be capable of being dissolved in a solvent, usually water. The HCL cannot ionize into H+ with the COOH ring in the Benzoic acid. Benzoic is hydrophobic in this solution.
Alanine is an amphoteric substance: both acidic and basic at the same time. However, it is neutral in a pH = 6.1 solution: CH3CH(NH3+)COO- It is positvely charged ( by excess of H+) at lower pH sol'n CH3CH(NH3+)COOH and negatively in pure water or more basic solution CH3CH(NH2)COO-.
An organic acid with a COOH group is called a carboxylic acid.
