amino acid molecules are water soluble meaning they cannot enter the cell. Fatty acid molecules CAN enter the cell.

Which compound contains both carboxyl and amino functional groups in the same molecules?

amino acid


Which part of the amino acid molecule changes and which are the same in all amino acid?

In an amino acid molecule, the part that changes is the side chain, or R group, which varies among different amino acids and determines their unique properties. The parts that remain the same in all amino acids are the central carbon atom (alpha carbon), the amino group (–NH2), the carboxyl group (–COOH), and a hydrogen atom. These consistent components are what classify the molecules as amino acids.


How does a mutation change a codon for one amino acid into a different codon for the same amino acid?

A mutation can change a codon for one amino acid into a different codon for the same amino acid through a process called silent mutation. This type of mutation occurs when a change in the DNA sequence does not alter the amino acid that is coded for, resulting in the same protein being produced.


How does a mutation that alters a codon for a specific amino acid to a different codon for the same amino acid affect protein synthesis?

When a mutation changes a codon for a specific amino acid to a different codon for the same amino acid, it usually does not affect protein synthesis. This is because multiple codons can code for the same amino acid, so the change may not alter the final protein product.


Each amino acid differs from others in the?

Each amino acid differs from others in the side chain, also known as the R-group, which gives each amino acid its unique properties and characteristics. The side chain contributes to the amino acid's ability to interact with other molecules and determines its role in protein structure and function.


Are glycine and carboxylic acid th same?

No, glycine is one of many different carboxylic acids. Carboxylic acids come in a wide variety ranging from formic acid to amino acids (which include glycine) and fatty acids.


Explain why proteins are considered polymers but lipids are not?

Proteins are made of amino acid chains. The repitition closely resembles the repeating unit, the monomer, from polymers. Lipids are made of trigyclerides and fatty acids, much smaller molecules than the protein, which is a macromolecule.


There can be more than one what for the same amino acid?

There can be more than one codon that codes for the same amino acid. This is due to the redundancy of the genetic code, where multiple codons can specify the same amino acid.


Is a sodium fatty acid salt the same as a carboxylic acid salt?

Yes, a sodium fatty acid salt is a type of carboxylic acid salt. Fatty acids are carboxylic acids with long hydrocarbon chains, and when they react with a base like sodium hydroxide, they form carboxylic acid salts such as sodium fatty acid salts.


There can be more than one for the same amino acid?

Yes, multiple codons can code for the same amino acid in the genetic code. This redundancy in the genetic code is known as degeneracy. For example, the amino acid leucine is specified by six different codons: UUA, UUG, CUU, CUC, CUA, and CUG.


Can more than one codon code for the same amino acid in the genetic code?

Yes, multiple codons can code for the same amino acid in the genetic code.


Organic molecules containing carboxyl groups are?

Organic molecules containing carboxyl groups are known as carboxylic acids. Carboxylic acids are characterized by the presence of a carboxyl group (-COOH), which consists of a carbonyl group (C=O) and a hydroxyl group (–OH) attached to the same carbon atom. They are widely found in nature and are important in biological processes.
