All amino acids that are found in proteins, except for proline, contain a(n); Group of answer choices amino group carbonyl group
Jobisdone [24]

Answer:

amino group

Explanation:

There are twenty (20) amino acids in nature. Generally, each amino acid is structurally made up of a central carbon atom called alpha carbon attached to a hydrogen, carboxylic acid group (-COOH) and an amine group (-NH2). However, one particular amino acid called PROLINE posseses an exception to this.

Proline, which is the only cyclic amino acid, is also the only amino acid that forms a secondary amine group i.e. loss of hydrogen atoms in its amine group when in a protein structure. This means that when in a protein, PROLINE does not have an AMINE GROUP.

A compound with an empirical formula of CH3 has a molar mass of 60.2 g/mol. What is its molecular formula?
disa [49]

Answer:

C₄H₁₂

Explanation:

The empirical formula gives you your smallest whole number ratio for the elements in the compound. Find the molar mass using a periodic table. We have one carbon (12.01 g/mol) and three hydrogens (1.008 g/mol). Therefore our molar mass for the empirical formula is 12.01 + 3(1.008) = 15.034 g/mol. To find the molecular formula divide the given molar mass by the empirical formula's molar mass 60.2/15.034 = 4.004257017 = 4. This number is the amount to multiply the empirical formula by to get the molecular formula, therefore your molecular formula is C₄H₁₂
