Detailed explanation-1: -Answer:-The general formula of an-amino acid is: H2N-CHR-COOH where, R = side chain Hence, the minimum number of carbon atoms in an-amino acid is 2—————-Answer 36):-A…
Detailed explanation-2: -Even though all organisms have differences, they still have one thing in common: the need for basic chemical building blocks. Amino acids have a two-carbon bond. One of the carbons is part of a group called the carboxyl group (COO-). A carboxyl group is made up of one carbon (C) and two oxygen (O) atoms.
Detailed explanation-3: -The minimum number of carbon atoms in a molecule should be 4 inorder to form a branched hydrocarbon.
Detailed explanation-4: -Their non-appearance in Earth life could suggest that amino acids having branched hydro-phobic chains with a maximum number of 4 carbons or single-carbon side chains are the preferred ones.
Detailed explanation-5: -In an alkene chain, at least 4 C atoms are required.
