Proteins: the macromolecule and the monomer: Proteins are about 50% of the dry weight of most cells, and are the most complex of the macromolecules we will talk about, because there are 20 different monomers or building blocks, called amino acids.
Beside this, what is the monomer used to make protein?
Explanation: proteins are made up of 21 different L-amino acids. these amino acids are joined together with peptide bonds. peptide bond is a bond between a caboxylic group of one amino acid with amino group of other amino acid.
What are the monomers of a protein?
Carbohydrates - monosaccharides. Lipids - glycerol and fatty acids. Nucleic acids - nucleotides. Proteins - amino acids.
What are the three parts of a protein monomer?
Amino acids are the monomeric building blocks of proteins. The α carbon atom (Cα) of amino acids, which is adjacent to the carboxyl group, is bonded to four different chemical groups: an amino (NH2) group, a carboxyl (COOH) group, a hydrogen (H) atom, and one variable group, called a side chain or R group (Figure 3-1).
