Answer: A membrane protein is defined as a protein that has an attachment to or is associated with a cell membrane or a cell organelle.
If one has a protein,the following will indicate that the protein is a membrane protein.
- They compose of the same
20 amino acids as contained in soluble protein.
- Sometimes, membrane protein attach itself to lipid moieties in a covalent manner.
- Unless they are anchored,they always diffuse liberally in the membrane.
- They sometimes attached to carbohydrates moieties covalently.
Inside of the cell is HYPERTONIC as compared to the outside
The correct answers are:
2) Peptide bonds form from nucleophilic attack by an electron pair on an alpha - amino nitrogen atom on an alpha - carboxyl carbon atom of another amino acid and
4) Peptides are polymers of amino acids.
A peptide bond is an amide type of covalent chemical bond. It is formed between two amino acids: C1 (carbon end) of one alpha-amino acid and N2 (nitrogen end) of another. Peptide bonds are the basis for the formation of a peptide chain and consequently protein. Formation of peptide bond is a condensation process, meaning that when two amino acids combine and link, water molecule is released and dipeptide is a product of that reaction.
The answer is identify and define
