Phenylalanine.
Phenylalanine is an essential amino acid that is converted into tyrosine through the enzyme phenylalanine hydroxylase. Tyrosine is an important precursor for several important molecules in the body, including epinephrine, dopamine, and thyroid hormones.
Melanin. It is found in most organisms. In animals melanin is made of the amino acid tyrosine.
By having more codons to code a particular amino acids, it makes it easier to produce in the cell and need to be supplemented from food(essential amino acids are normally not synthesized in our cell).

Essential amino acids are those the body cannot produce. There are 20 basic amino acids. There are eight essential amino acids unless the individual is a phenylketonuric. There are nine essential amino acids for phenylketonurics as they cannot convert phenylalanine to tyrosine. Essential amino acids have to be taken into the body by eating. This answer is for informational purposes only. All individuals should ask advice of their physician.
Yes, tyrosine is polar. It contains a hydroxyl group (-OH) which makes it polar due to unequal sharing of electrons in the molecule. This allows tyrosine to form interactions with other polar molecules or groups.

Vegetables are not the best source for essential amino acids because they do not contain all the essential amino acids in sufficient amounts. Animal sources like meat, fish, eggs, and dairy products are considered complete proteins because they contain all the essential amino acids in the right proportions.
From what I understand is that your body can make protein from the amino acids it makes in your cells. Well, there is 8 essential Amino Acids that your body can not make. That is why we eat animal proteins( such as eggs, milk, meat, and fish) because they contain those 8 essential amino acids. There is Essential Amino Acids in plants, just there is very rarely all 8 of the essential amino acids.So one of the main reasons we eat proteins is to get the essentail amino acids. With these Amino acids, your body can make the protein it needs.
Non-essential amino acids can be synthesized by the body through various metabolic pathways utilizing precursor molecules such as glucose, fatty acids, and other amino acids. They do not need to be obtained through the diet because the body can produce them internally.
