What is one product of a condensation reaction between two amino acids, such as glycine and alanine?

Ipatiy [6.2K]

Answer:

Gly-Ala

(Dipeptide).

Explanation:

A condensation reaction is a reaction in which two molecules combine to form a single molecule with the loss of a small molecule e.g water.

When two amino acids, such as alanine and glycine react, they yield a mixture of dipeptides (via dipeptide bond) and water. That is, The −OH from the carboxyl group (-COOH) of one amino acid combines with a hydrogen atom from the amine group (-NH2) of the other amino acid to produce water.

Consider the substances below.

ratelena [41]

Answer:

They have the same number of atoms. = YES

They have different masses. = YES

Explanation:

1 mol of beryllium

• 1 mol of salt

beryllium = Be = Atomic mass: 9.012182

salt = NaCl = Molar mass: 58.44 g/mol

1 mol of water

• 1 mol of hydrogen

water = H2O = Molar mass: 18.01528 g/mol

hydrogen = H = 1g/mole

Which statement is true about these substances?

They have exactly the same mass. = NO

They have different numbers of particles = NO

They have the same number of atoms. = YES

They have different masses. = YES

Avogadro constant means the number of units in one mole of any substance (defined as its molecular weight in grams) is equal to 6.02214076 × $10^{23}$ .
