BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Answer and Explanation: Proteins are made of smaller units called amino acids. Amino acids are compounds containing carbon, oxygen, hydrogen and nitrogen bonded together to make specific molecules. Amino acids are then bonded to each other in varying sequences and numbers to make specific proteins.

Detailed explanation-2: -Subunits are the polypeptide chains that are assembled (usually non-covalently) to make up the protein. For the purposes of BIOML, a subunit is any peptide components of a protein that are the results of the translation of a single mRNA.

Detailed explanation-3: -Protein Structure and Function The most common number of subunits is either 2 (dimer) or 4 (tetramer), but trimers, pentamers, and hexadecamers and higher order structures also occur.

Detailed explanation-4: -Each amino acid is structured from an amino group and a carboxyl group bound to a tetrahedral carbon. This carbon is designated as the -carbon (alpha-carbon). Amino acids differ from each other with respect to their side chains, which are referred to as R groups.
