What in amino acids?

Answer 1

Amino acids are the basic building blocks (monomers) of proteins. Two amino acids joined together by peptide bonds forms a dipeptide. Many amino acids in a chain form a polypeptide. One or many polypeptides folded/folded together form/s a protein.

There are twenty common amino acids (examples are alanine, tryptophan, methionine and valine). They all consist of a central carbon atom linked to an R group (also called a side chain), a hydrogen atom, an amino (NH2) group and a carboxylic acid (COOH) group. The different amino acids (like the 4 examples above) differ in the structure of their R groups.

Glycine's R group is a single H atom. Phenylalanine's R group differs from alanine's R group by a phenyl group. Alanine's R group is simply CH3 (a methyl group).

Answer 2

Non polar amino acids are alanine, cysteine, glycine, isoleucine, leucine, methionine, phenylalanine, proline, tryptophan, tyrosine, and valine. Polar amina acids are arginine, asparagine, aspartic acid, glutamine, glutamic acid, histidine, lysine, serine, and threonine.

Answer 3

Proteins are formed from various amino acids. Essential amino acids are those that are "essential" in the diet. In other words, we cannot create them through our own metabolism.
Non-essential amino acids are those which can be produced from other amino acids and substances in the diet and metabolism. Altogether there are 21 that we use to make proteins.
