How many different primary structures could be formed using the four amino acids alanine, phenylalanine, serine and valine? Write the amino acid sequences (using the three letter code) of all the possible peptides that begin with phenylalanine. You must use each amino acid once and only once in each peptide.

Common proteins are polymers of 20 different amino acids. How many amino acids are necessary for a protein polymer to have at least as many possible different sequences as there are atoms in the Universe? (There are about 2 × 1056 moles of atoms in the Universe.) *Note - The answer is a mathmatical answer. I need an explanation of the math behind this problem.

Turkey (protein) has many essential amino acids such as tryptophan, threonine, isoleucine, lysine and phenylalanine. Threonine is a large amino acid and will broken be down into two products: pyruvate and succinyl CoA which are then fed into the citric acid cycle and electron transport chain. Phenylalalanine is broken down into acetyl CoA and fumarate and fed into the citric acid cycle and electron transport chain. Mayonnaise (fatty acid) has omega 3 alpha linolenic acid (18:3Δ9,12,15) and omega 6 linoleic...
